ABSTRACT:
Prevention of detrimental effect of metals such as nickel, vanadium and iron on the activity of a cracking catalyst when used in a cracking process having essentially no hydrogen added thereto is achieved by using in the cracking process novel cracking catalyst having less than 40 weight percent zeolite content and including antimony metal or a compound of antimony prior to subjecting the cracking catalyst to hydrocarbon cracking conditions.
