SO{HD 2 {B Stripping in fluorosulfuric acid catalyst regeneration

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.
