PASSIVATION OF METAL CONTAMINANTS IN THE CATALYTIC CRACKING OF HYDROCARBONS |
摘要 |
An improved composition and method for passivating vanadium on or in a catalytic cracking catalyst during the process of catalytic cracking of hydrocarbons is described. The improved method comprises mixing discrete particles of lanthanum oxide and, optionally, other rare earth oxides along with the catalyst and the hydrocarbon during the catalytic cracking process. |
