    摘要： The present invention provides a method for separating conjunct polymers which are formed as byproducts of acid catalyzed isoparaffin-olefin alkylation and sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid comprising the sequential steps of:(a) separating hydrofluoric acid from said mixture to provide an intermediate stream containing less than about 30 percent hydrofluoric acid by weight;(b) gravitationally separating said intermediate stream into a more dense sulfolane-enriched stream and a less dense conjunct polymer-enriched stream;(c) distilling said more dense sulfolane-enriched stream of step (b) to provide an overhead stream containing a higher sulfolane concentration than said more dense sulfolane-enriched stream of step (b) and a bottom stream enriched in conjunct polymers.

    摘要： A single path process for alkylating a hydrocarbon feedstock containing an olefin and an isoparaffin is disclosed. The process includes dispersing an acid-based liquid alkylation catalyst into a reaction zone for contact with a continuous hydrocarbon phase. The process further includes separating the hydrocarbon phase from the acid catalyst upon completion of the alkylation reaction and providing a continuous on-line regeneration of the entire volume of catalyst once it has been separated from the hydrocarbon phase.

    摘要： The present invention provides an acid catalyzed isoparaffin-olefin alkylation process which improves process stability and safety by storing the acid in an excess of an additive which reduces the fuming tendency of the mixture, for example, a sulfone. Acid is stripped from the additive and concentrated prior to charging the acid to the alkylation reaction zone. Specifically, because the stored solution of acid in the additive is more dilute than can be effectively used for isoparaffin-olefin alkylation, the acid is concentrated prior to charging the catalyst mixture to the reaction zone. The invention solves the problem of conjunct polymer accumulation by diluting the conjunct polymer with a relatively large volume of the additive and continuously regenerating a slipstream of the dilute acid/additive mixture.

    摘要翻译： 本发明提供了一种酸催化的异链烷烃烯烃烷基化方法，其通过将酸储存在过量的添加剂中来提高工艺稳定性和安全性，这降低了混合物例如砜的发烟趋势。 在将酸加入到烷基化反应区之前，从添加剂中除去酸并浓缩。 具体地说，由于储存在添加剂中的酸溶液比可以有效地用于异链烷烃 - 烷基化烷基化更为稀释，所以在将催化剂混合物装入反应区之前将酸浓缩。 本发明通过用相对大量的添加剂稀释结合聚合物并连续再生稀酸/添加剂混合物的滑流来解决聚合物聚合物积聚的问题。
