ABSTRACT:
A startup procedure for an alkylation process in which a stream of an olefinic material is mixed with an acid stream and polymerized to cause formation of a polymeric diluent for the high strength acid which is initially charged to the alkylation process. This quickly lowers the strength of the acid, which results in an improved alkylate quality, during the initial period of operation in which the prior art relies on the relatively slow natural buildup of alkylation reaction by-products as a diluent.
