Abstract:
A process for the production of linear alkylbenzenes, comprising:contacting benzene and an olefin having about 8 to about 30 carbons in the presence of a mixed catalyst bed to form linear alkylbenzenes, wherein the mixed catalyst bed comprises fluorine-containing mordenite and a second, solid linear alkylbenzene alkylation catalyst, wherein the second alkylation catalyst has a selectivity to the 2-phenyl isomer of the linear alkylbenzenes less than the selectivity of the fluorine-containing mordenite,wherein the mordenite has been treated by contacting the mordenite with an aqueous hydrogen fluoride solution, wherein the hydrogen fluoride in the aqueous solution has a concentration in the range from about 0.1 percent to about 1 percent by weight.
