Benzene reduction in gasoline by alkylation with higher olefins
A benzene-rich gasoline stream is alkylated with higher olefins in contact with a fluid bed of shape selective zeolite catalyst to produce a gasoline product stream reduced in benzene content wherein the high octane value alkylaromatics formed by benzene alkylation are of low carbon number, essentia...

| description | A benzene-rich gasoline stream is alkylated with higher olefins in contact with a fluid bed of shape selective zeolite catalyst to produce a gasoline product stream reduced in benzene content wherein the high octane value alkylaromatics formed by benzene alkylation are of low carbon number, essentially C10-. Concurrently, a portion of olefins in the gasoline stream are converted to gasoline boiling range hydrocarbons and the sulfur content of the gasoline feedstream is lowered. Besides enhancing the octane value of the feedstream, the process results in a lower Reid vapor pressure and lower sulfur content. |
