Description:

This paper focuses on seven commercial trials of a new, rare earth based, dual particle trapping technology known as RV4+. RV4+ is one of several trapping technologies offered in our ResidcatB series of cracking catalysts. The importance of vanadium mobility to traps is discussed and both laboratory and commercial data is presented. Vanadium reductions on equilibrium catalyst as high as 23.4% were observed with as little as 4.3% material in inventory. RV4+‘s affinity for vanadium was as high as six times that of fluid cracking catalyst. Improvements in equilibrium catalyst microactivity were observed that were directly related to higher zeolite surface area, a sure sign that the effects of vanadium were being mitigated. One refiner was able to reduce fresh catalyst additions by 20% and still maintain activity. No sulfur interference was observed during the commercial trials.
