Описание:
The article presents the results of the work on lanthanum excretion from spent petroleum hydrocar- bon cracking catalyst by mineral acids processing. Methods of receiving lanthanum compounds in the form of insoluble compounds (carbonates and hydroxides) from acid extracts have been validated. The experimental data characterizing the structure and properties of the received sediments, and allowing to prove the possibility of using spent cracking catalyst as raw material for obtaining rare-earth elements are given.
