ABSTRACT:
In a hydrocarbon fluid catalytic cracking process, high concentrations of sodium in the hydrocarbon entering the reactor will poison the reaction sites on the FCC catalysts, thereby reducing the efficiency of the cracking process. The addition of an aluminum compound to the hydrocarbon significantly reduces the poisoning effect of the sodium on the catalyst. The aluminum compound may be selected from the group consisting of aluminum nitrate, aluminum isopropoxide, aluminum oxide and sulfate salts of aluminum.
