Description:
Vanadium, present to varying degrees in FCC feed, deposits on the catalyst virtually quantitatively in the cracking process. In resid operations, vanadium levels on catalyst can reach 10,000 ppm at typical catalyst make-up rates. Once on the catalyst, vanadium destroys the zeolite and restricts access to active sites. This reduces catalyst activity. Although not as much of a problem as nickel, vanadium is also a dehydrogenation catalyst, producing modest increases in hydrogen and coke.
