  • Process for producing an alkylated, non-oxygen-containing aromatic hydrocarbon
    Patent number: 5922922
    Abstract: An alkylated aromatic hydrocarbon is produced having the following properties: (a) less than 40 wt. % of the alkylated aromatic hydrocarbon is 2-aryl; and (b) at least 20 wt. % of the alkylated aromatic hydrocarbon is a monoalkylate. That alkylated aromatic hydrocarbon is produced by isomerizing a normal alpha-olefin having from 20 to 28 carbon atoms in the presence of a first acidic catalyst to produce a partially-branched, isomerized olefin, then either benzene or toluene is alkylated with the partially-branched, isomerized olefin in the presence of a second solid, acidic catalyst. The first acidic catalyst can be a molecular sieve with a one-dimensional pore system. The second acidic catalyst can be a zeolite Y having a silica to alumina ratio of at least 40:1.
