Alkylation catalyst regeneration utilizing polyvinylpyridine and amine substituted styrene divinylbenzene copolymer contact materials |
| abstract |
Described is a novel process for regenerating an ASO contaminated alkylation catalyst containing a sulfone component and a hydrogen halide component. A sulfone-containing mixture containing ASO and which is derived by the removal of a major portion of the hydrogen halide component of the alkylation catalyst is contacted with a reversable base selected from the group consisting of polyvinyl pyridine, amine-substituted styrene divinyl benzene copolymer and mixtures thereof so as to remove at least a portion of the ASO component from the sulfone-containing mixture to thereby produce a treated sulfone-containing mixture. The treated sulfone-containing mixture can further be processed by contacting it with an absorbent material which can include carbon and alumina. |
