Abstract

Application of oxidative regeneration of zeolite-containing catalysts to alkylation of isobutane by olefins was investigated during long-term catalyst tests at a pilot plant. This approach to regeneration was found to shorten the catalyst service life between regenerations. Local overheating of the catalyst is presumed to cause irreversible sintering and, as a result, a decrease of alkylate yield
