    摘要: Disclosed is an alkylation process which utilizes a catalyst containing hydrogen fluoride, and, optionally, a volatility reducing additive, as an alkylation catalyst. The process provides for the regeneration of an alkylation catalyst having ASO, and, optionally, a volatility reducing additive, therein by separating HF from the ASO and the optional volatility reducing additive components using an upwardly flowing gas containing an isoparaffin and/or an olefin. Where a volatility reducing additive is used, the ASO and volatility reducing additive are thereafter separated to provide a volatility reducing additive which is substantially free of ASO.

    摘要: C.sub.4 -C.sub.15 alkanes (preferably C.sub.4 -C.sub.8 alkanes) are disproportionated in the presence of at least one alkylaluminum chloride (preferably isobutylaluminum dichloride), at least one chloroalkane (preferably carbon tetrachloride), and at least one solid material (selected from a group comprising alumina, silica, aluminosilicates, various other aluminum compounds, various boron compounds, and sulfonated styrene polymers).
