Main Approaches to Creating Nitrogen-Resistant Cracking Catalysts

Resumo

Data are presented on the modification of cracking catalysts in order to improve their resistance to the poisoning effect of nitrous compounds of various classes. The modification of the catalyst matrix consists in that special additives are introduced into the catalyst formulation to improve its resistance to the poisoning action of nitrous compounds. Acid-activated clays and mixed oxides are considered as these additives.
