EURECAT has extensive experience testing the HDS activity of regenerated hydrotreating catalysts using pilot plant reactors. Newer generations of catalysts require post-treatment after regeneration and their activity is less predictable based only on surface area and contaminant levels. True performance is best measured through pilot plant testing of regenerated catalyst activity rather than just estimating it. EURECAT can measure both the HDS and HDN activity of regenerated CoMo or NiMo catalysts to provide an activity value for customers to make informed decisions about catalyst reuse.

- 1. Will Your Regenerated Catalyst be a Thoroughbred Again? The EURECAT R&D Group has a vast YOU CAN’T JUDGE A HORSE BY ITS amount of experience with activity testing on hydrotreating catalysts. Our first pilot COLOR ANYMORE plant MDSU was installed in 1996 and was Introduction of the latest generation Type II and balanced Type I/Type II catalysts used extensively to determine the HDS has shaken up the catalyst regeneration universe. Many of these catalysts require activity of regenerated catalysts as part of post-treatment after regeneration, and unfortunately the post-regen activity is our pool management services. much less predictable using only the data traditionally gathered in a regeneration The introduction of low and ultra-low sulfur study such as surface area and contaminant levels. specifications for diesel required testing with With today’s advanced rejuvenation techniques, a critical determining factor for increasingly deep HDS regimes. Two new MIF units were purchased in 2003 to carry catalytic activity is re-dispersion of the active metals. True catalyst performance is out testing at these new conditions.

Expressed as RVA or RWA versus the fresh response was the installation of a Multi- reference catalyst, the activity value provides you with a sound decision basis. Tube test Unit (MTU) which allows testing of 10 samples in 10 parallel reactors of 10 ml each. The MTU runs a three condition protocol and has proven to be extremely reliable. Based on this success, a second MTU was installed in 2010, increasing EURECAT’s total number of test reactors to 22.

- 2. ACTIVITY TESTING APPLICATIONS ULTRA LOW SULFUR DIESEL HYDROTREATING (HDS) The majority of the catalysts we test belong to the ULSD category, where the investment and operational risks associated with regeneration and rejuvenation of the catalyst justify an HDS activity test before the catalyst is reused. Activity testing is an essential and dependable quality control tool, allowing the transfer and reuse of your catalyst batch within the corporate catalyst pool. Eurecat tracks the activity values for various lots in catalyst pools we manage for several refining majors, allowing the customer to carefully manage when and where each lot is applied with minimum risk exposure. Our standard MTU test protocol measures catalyst performance at 3 different levels of severity utilizing straight-run gasoil (1.2 wt% S) at the following conditions: WABT: 640 / 650 / 660 °F LHSV: 2 h-1 pressure: 580 psi H2/oil: 300 EURECAT’s extensive database on activity testing contains a wealth of process and catalyst knowledge. Shown below is an example of a study carried out by EURECAT to assess the effects of different contaminants on the activity of REACT™ treated KF-757. HORSE TRADING If you don’t have a requirement to reuse your catalyst within your own refinery, having it activity tested by EURECAT will open the door to selling it to an affiliated refinery or to a third party. EURECAT’s catalyst purchase and resale network is shared between our affiliates in the USA, France, Italy, Saudi-Arabia and India. Our worldwide sourcing efforts assure a steady supply and demand for regenerated catalysts. In addition, the catalyst pools we manage for several customers are often in undersupply or oversupply of exactly HYDROCRACKER / FCC PRETREATMENT (HDN) the catalyst that you may wish to sell or HDN performance of NiMo catalyst in HC-PT or FCC-PT conditions is tested in a dedicated purchase. format on LCO feed at an operating pressure of 1450 psi (100 bar). Contact EURECAT today for a qualified NON-STANDARD HYDROTREATING TEST FORMATS regenerated catalyst and buy a race- horse for a workhorse price. EURECAT will gladly develop a customized testing protocol for your specific process or R&D application. Our MIF testing unit is extremely flexible in terms of operating temperature, pressure, LHSV, and H2/oil ratio. Various feed types can also be utilized. HYDROGENATION ACTIVITY / SELECTIVITY TEST In addition to CoMo and NiMo catalysts, EURECAT can also test your Palladium selective hydrogenation catalysts for activity and selectivity, comparing it to the performance of fresh Leading the Race catalyst.
