Abstract
The present invention, therefore, is directed to a novel method for improving conversion in a fluidized catalytic cracking unit feed stream containing vanadium. According to the method, an effective amount of a composition comprising at least one overbase complex of a magnesium or aluminum salt or a mixture thereof and an organic acid complexing agent is incorporated into the feed stream.
Claims21
A method for improving conversion in a fluidized catalytic cracking unit feed stream containing vanadium, comprising incorporation into the feed stream an effective conversion improving amount of a liquid composition comprising at least one overbase complex of a salt and an organic acid complexing agent, the salt being selected from the group consisting of magnesium salts, aluminum salts and mixtures thereof.
A method for scavenging vanadium in a fluidized catalytic cracking unit feed stream containing vanadium, comprising incorporation into the feed stream an effective conversion improving amount of a liquid composition comprising at least one overbase complex of a salt and an organic acid complexing agent, thereby to scavenge vanadium in the feed stream, the salt being selected from the group consisting of magnesium salts, aluminum salts and mixtures thereof.
A method for prolonging the life of a catalyst in a fluidized catalytic cracking unit feed stream containing vanadium, comprising incorporation into the feed stream an effective conversion improving amount of a liquid composition comprising at least one overbase complex of a salt and an organic acid complexing agent, thereby to prolong the life of the catalyst, the salt being selected from the group consisting of magnesium salts, aluminum salts and mixtures thereof.
