Episode 3 : Production of Synthesis Gas by Steam Methane Reforming
History of Synthesis Gas
In 1780, Felice Fontana discovered that combustible gas develops if water vapor is passed over carbon at temperatures over 500 属C. This CO and H2 containing gas was called water gas and mainly used for lighting purposes in the19th century.
As of the beginning of the 20th century, H2/CO-mixtures were used for syntheses of hydrocarbons and then, as a consequence, also called synthesis gas.
Haber and Bosch discovered the synthesis of ammonia from H2 and N2 in 1910 and the first industrial ammonia synthesis plant was commissioned in 1913.
The production of liquid hydrocarbons and oxygenates from syngas conversion over iron catalysts was discovered in 1923 by Fischer and Tropsch.
Much of the syngas conversion processes were being developed in Germany during the first and second world wars at a time when natural resources were becoming scare and alternative routes for hydrogen production, ammonia synthesis, and transportation fuels were a necessity.
In 1943/44, this was applied for large-scale production of artificial fuels from synthesis gas in Germany.

THE IMPACT OF Na2SO4 and MgSO4 AS ELECTROLYTE ADDITIVES ON THE EFFICIENCY AND...IRJET Journal
油
This document analyzes the impact of adding Na2SO4 and MgSO4 electrolyte additives to lead-acid batteries. Charge and discharge cycling tests were conducted on batteries with the original electrolyte and electrolytes mixed with the additives. The key findings were:
1. Batteries with Na2SO4 additive showed improved charge voltages, longer discharge times, and higher efficiencies compared to the original electrolyte.
2. Batteries with MgSO4 additive showed some improvements in charge voltages but less enhancement of discharge performance and efficiency compared to Na2SO4.
3. The addition of Na2SO4 was found to most effectively improve the cycle life and performance of the lead-
Lead acid batteries have a limited lifespan that depends on factors like temperature, depth of discharge, charging/discharging rates, electrolyte levels, and age. Higher temperatures significantly reduce battery life - for every 8.3属C above 25属C, battery life is halved. Frequent deep discharges and overcharging also decrease battery lifespan by accelerating corrosion. Maintaining proper electrolyte levels and charging methods helps maximize the battery life cycle.
Charging sealed lead acid (SLA) batteries requires an intelligent charger to maximize battery life. Simple constant current or constant voltage chargers can reduce battery life expectancy. Maximizing battery life involves understanding the battery's chemistry and using a multi-stage charging technique that includes a bulk constant current charge, absorption constant voltage charge, and float intermittent charge while monitoring voltage and temperature. An intelligent charger that implements temperature compensation can optimize charging to extend battery life.

Authors confirm that they were able to split chemical and electrical parts inside chemical battery thanks to matching parameters of digit currents and voltages
The main output of this split is full reduction of polarization part in internal resistance due to shift in electric neutrality. We would like to share some test results we have been doing for 5 years.
This document summarizes the Hydro-Electric Pulse Power (HEPP) wastewater treatment technology. HEPP uses an underwater, high-voltage spark to break down organic compounds, precipitate dissolved solids, and disinfect pathogens. Test results showed HEPP reduced contaminants like BOD and coliform to a fraction of their original levels. While HEPP has lower capital and operating costs than SBR systems, it introduces a radically new technology that could face resistance in the conservative wastewater industry. The document recommends evaluating HEPP further through independent testing at a wastewater treatment plant.
The document discusses how to recondition lead-acid batteries using a desulfator to restore them to near 100% capacity. It explains that over time, sulfates build up on the lead plates in batteries, reducing their charge-holding ability. A desulfator sends pulses through the battery to break up these sulfates, allowing them to dissolve back into the battery acid. The reconditioning process takes 1-3 weeks and involves charging, discharging, and monitoring the voltage until it reaches 13.6-14.8 volts, restoring the battery's capacity and extending its usable life by years. Reconditioning batteries is worthwhile as it can save $90 or more on replacement costs for each battery treated.
1) Acid stratification and low charge levels can cause battery failure by concentrating acid in parts of the battery cells, leading to grid corrosion and quicker sulfation.
2) The Dynapulse248 battery recovery system uses high voltage pulses to break up sulfation on battery plates and allow the battery to accept a charge again.
3) The system has 8 voltage settings to match different battery types and uses the battery's voltage and resistance as feedback to control the pulse process automatically.

Lets discuss Standby Letter of Credit vs Bank Guarantee, which is a common confusion in the minds of many. A standby letter of credit and a bank guarantee are actually very similar products. As a matter of fact, if we go back and look at the origination of the standby letter of credit, we may be able to understand the similarity better.
Under the Glass-Steagall Act, passed by the US Congress in 1933, banks were not allowed to participate in investment banking activities. Consequently, they couldnt issue a bank guarantee as well. As this was a lucrative business, they got around this act by forming their letters of credit as bank guarantees. They called this new product the standby letter of credit. From this, we can infer that the standby letter of credit is actually a hybrid version of a bank guarantee.

A means of declaring affection for the last but some thousand years, the rose is a perennial symbol. The passionate love is represented by red, admiration by pink, and purity by white. Romantic gifts: bouquets, poetic mentions, permanence in keepsakesa rose is the last word in romance! It conveys warmth, devotion, and love everlasting.
How can TWINT be agile in an inert ecosystem?BATbern
油
The Swiss banking Ecosystem works as a trustworthy and reliable basis for personal and business-related financial transactions. A fintech in this field is dealing with large and globally active players who cant (and likely shouldnt) adapt as fast and as agile as the fintech can, and must, to secure its position in the market. In this presentation I will elaborate in which ways TWINT strives for agility and innovation in an otherwise slow-moving and slowly innovating ecosystem.
2. 1) Do you want to save your battery life ?
2) Do you want to save your money ?
3) Do you want to save our earth ?
4) Do you want to save our next generation ?
5) Do you want to go green ?
3. Introduction
As many as 70% to 80% of lead-acid batteries are replaced
prematurely due to the sulphation that occurs on lead plates
regardless of maintenance. Sulphation is an electrochemical
reaction that occurs when a battery is discharged.
During normal use or in storage, a batterys sulfuric acid is active
between the plates. This reaction creates energy in the form of
electric current.
It also transforms the acids chemical composition that is in
contact with the lead plates, forming a solid residue (lead sulfate).
This continual sulfate accumulation accelerates the weakening
process and finally suffocates the battery.
4. EFFECTS OF SULPHATION
Sulphation reduces the electrolyte concentration
Thus the cell voltage is also reduced.
As sulphation increases, the internal resistance
increases Added heat generation produces a
marked rise in temperature.
These higher temperature further accelerates in dry-
out processes culminates in the early failure of a
battery.
Sulphated Plate
Cont.
5. General lack of capacity (deliverable power).
An increase in battery temperature while charging or
discharging.
A strong odor of hydrogen gas while charging or discharging.
An excessive use of water and a rapid rise in battery voltage
while charging (stops the charger).
6. Following recommended battery maintenance procedures may
keep your batteries operational for the typical 5 to 7 years of
standard battery life.
The earlier you treat a battery, the better. The battery will
maintain its health and will have an even longer service life.
The newer the battery, the more likely you can double, triple or
even quadruple its expected service life. Note the battery
must be functional.
Physically damaged batteries or batteries with dead cells cannot
be treated with our process.
Battery regeneration is a procedure that returns a sulfated
battery to its original and normal condition.
REVIVAL Battery Clinic ++ regenerates sulphated batteries
utilizing an electro-chemical sulphation reversion process.
HOW TO REDUCE SULPHATION ?...
7. Sulphation of the internal plates rises resistance in the battery
making it impossible to work to its full potential.
Our REVIVAL Battery Clinic ++ Regenerator successfully reverse
the sulphation process, converting lead sulphate crystals back
into active matters by applying a very high frequency pulse in
several steps. This process restores battery capacity, giving you
the ability to still use old and sulphated batteries and extend the
life of your energy assets.
REVIVAL Battery Clinic ++ cleans and maintains battery plates
and separators by dissolving lead sulfate crystals.
During the de-sulphation treatment, the sulphate residue melts
slowly and progressively returning to the batterys acid.
How REVIVAL Battery Clinic ++ works ?...
8. REVIVAL Battery Clinic ++ restores the battery plate composition
and improves performance allowing the battery to operate at its
optimum capacity, often well beyond its original specifications.
REVIVAL Battery Clinic ++ Regenerator" uses cutting edge
technology to send a specially controlled pulsing DC current into
the battery.
The current pulses convert battery-killing sulphate crystals back
to liquid molecules in the electrolyte. The battery stays in top
condition and its lifespan is dramatically extended.
9. WHY REVIVAL Battery Clinic ++ ?...
Reduces the capital and operational expenditure.
Improves battery performance and efficiency. Reduces charging
time and increases working time between charging.
Increase in the workers productivity.
Reduction of electric consumption.
Increase of Life Expectancy shifts from an average of 4 to 8 years,
ensuring the battery capacity > 70% during the 8 years.
Most professional piece of technology available in today's market
to service batteries: multi voltage, multi chemistry, Discharging,
charging, bad cell detection, software, reports....
Process from finish to start maximum 30-40 hours and a
fully detailed report in pdf, word or excel on the results.
10. REVIVAL Battery Clinic ++ has become the dedicated brand
name of Revival Engineers specialized in
battery regeneration with many happy and returning customers.
Our REVIVAL Battery Clinic ++ is specifically designed to analyze
and regenerate all types of lead acid batteries; we have very nice
references in different industry sectors.
Regeneration is very popular and becomes a real asset
management tool because 80 percent of the batteries breaking
down and losing capacity are sulphated and can be restored with
the right treatment.
Our REVIVAL Battery Clinic ++ can also be used for annual
maintenance which strongly extends the lifespan of the
batteries.
With our Repulse technology we can do what others cannot
provide: to prove the results after regeneration.
11. REVIVAL Battery Clinic ++ equipment is a combo of a regenerator and
discharger . The voltage, current, time and temperature are all
monitored throughout the whole process and the data can be
transferred wireless to your computer. With this data, a full report on
the batterys condition can be made with our software.
The regeneration process should be started with a fully charged
battery.
Our REVIVAL Battery Clinic ++ regenerates the battery in several
steps. Starting with a discharge, followed by regeneration,
equalization, another discharge and ending with another regeneration
mode.
The Process
12. After the whole process the data of Discharge 1 and 4 can be
compared, making it easy to see the difference in capacity and internal
resistance of the battery before and after.
(Please take a look at the added file called Results Regeneration for
more info on how to analyze the results).
We even go one step further. If combined with our
optional Battery Monitoring System, we are capable of detecting
which cell in your battery bank is the one causing the battery to run
down too fast. The BMS system permits to monitor the voltage of each
individual cell every three minutes during charge and discharge. This is
giving you the ability to make a full analysis of the battery up to cell
level. The measurements are stored fully automatic, which means
the regenerator and BMS work autonomously and do not have to be
supervised while regenerating a battery.
