METHOD FOR DEMERCAPTANIZATION OF PETROLEUM DISTILLATES Russian patent published in 1998 - IPC

Abstract RU 2106387 C1

FIELD: petroleum processing. SUBSTANCE: distillates are treated by air oxygen in presence of heterogeneous catalyst containing copper sulfate applied on carbon fibrous fabric, while catalyst is periodically replenished with 0.1-1% aqueous sodium hydroxide solution in amount 0.01-0.1% NaOH based on catalyst weight, replenishment being started after 50-100 h of catalyst operation. EFFECT: increased demercaptanization degree and catalyst activity.
