Patent

CA 2194902

This invention discloses an integrated process of alkylation of olefins and regeneration of spent sulfuric acid. The alkylation of olefins may be replaced by nitration of toluene or by chlor-alkali process. The sulfuric acid is used as a catalyst or a absorbent, and the spent sulfuric acid is regenerated in situ and is recycled in the alkylation of olefins, nitration of toluene or chlor-alkali processes.

Il s'agit d'un procédé intégré d'alkylation des oléfines et de régénération de l'acide sulfurique épuisé. L'alkylation des oléfines peut être remplacée par la nitration du toluène ou par des procédés au chloralkali. L'acide sulfurique est utilisé comme catalyseur ou comme absorbant, et l'acide sulfurique épuisé est régénéré in situ et recyclé avec l'alkylation des oléfines, la nitration du toluène ou les procédés au chloralkali.
