abstract


The influence of leaching agent nature of process on lanthanum leaching ratio from spent petroleum hydrocarbon cracking catalyst has been established. It has been identified that aluminum is extracted in addition to lanthanum by the acid leaching of waste catalyst. The methods of lanthanum precipitation over aluminum from waste cracking catalyst leaching solutions by evaporation of nitrate leaching solution have been proved. Directions to use lanthanum-containing products have been offered.
