TRATTAMENTO CON SO2 NELLA RIGENERAZIONE DI CATALIZZATORE ABASE DI ACIDO FLUOROSOLFORICO.

摘要

Sulfur dioxide is employed as a stripping agent in the regeneration of a deactivated or partially deactivated alkylation catalyst containing fluorosulfuric acid, thereby eliminating undesirable reactions that occur between the acid component of said catalyst and the hydrocarbon stripping agents normally employed in conventional fluorosulfuric acid regeneration processes.
