METHOD OF REDUCING SULFUR OXIDE CONTENT IN RECOVERY GAS Russian patent published in 1997 - IPC

Abstract RU 2072251 C1

FIELD: catalytic processes in petroleum processing. SUBSTANCE: oxidative recovery of coked catalysts on hydrocarbon cracking plants provided with regenerator and catalyst-circulation system involves simultaneously adding into regenerator a platinum-containing carbon monoxide oxidation catalyst and a catalyst for binding nitrogen oxides. Ratio of the two catalyst is ranged from 1: 2 to 1: 70 and platinum content in circulation system is 0.02-0.10 ppm. EFFECT: enhanced recovery of catalyst and improved environmental condition.
