Abstract
Disclosed is a process and apparatus for alkylating light olefin with benzene at near but less than full conversion of the olefin. We have found that stopping below full conversion of the olefin maximizes yield of monoalkylbenzene.
Claims13
A process for reacting an olefinic stream comprising ethylene with an aromatic stream comprising benzene to obtain an alkylaromatic product stream comprising ethylbenzene, the process comprising:
- delivering the olefinic stream to a reactor vessel containing an alkylation catalyst comprising at least one of beta zeolite and UZM-8 zeolite;
- delivering the aromatic stream to said reactor vessel;
- contacting ethylene in said olefinic stream and benzene in said aromatic stream with said alkylation catalyst to obtain alkylaromatics comprising ethylbenzene under alkylation conditions including a conversion of ethylene in said olefinic stream ranging from at least 97% to no more than 99.5%;
- and
- recovering the alkylaromatic product stream comprising ethylbenzene.
