1. An acid catalyst effective for a conversion of a hydrocarbon, comprising: a molar ratio of a compound containing Al to a compound containing a heteroatom of 5 or greater, greater than 20 wt % halide-containing conjunct polymer, and a Lewis acid; wherein less than 0.1 wt % solid precipitates from the catalyst when it is held for three hours or longer at 25° C. or below; wherein the conversion is an alkylation, an isomerization, a hydrocracking, a polymerization, a dimerization, an oligomerization, an acylation, an acetylation, a metathesis, a copolymerization, a dehalogenation, a dehydration, an olefin hydrogenation, or combinations thereof; wherein at least 33 wt % of the hydrocarbon is converted; wherein the heteroatom is selected from the group of N, P, O, S, and combinations thereof; and wherein the acid catalyst comprises an ionic liquid catalyst made of two components, a first component being a Lewis acid compound of Group 13 metals and a second component being an organic salt characterized by a general formula Q+A−, wherein Q+ is an ammonium, phosphonium, oxonium, or sulfonium cation and A− is a negatively charged ion. |
