Abstract
Process and catalyst for upgrading gasoline comprising durene (1,2,4,5-tetramethylbenzene) and pseudodocumene, the process comprises hydroisomerization of durene (1,2,4,5-tetramethylbenzene) and pseudocumene (1,2,4-trimethylbenzene) contained in the gasoline in presence of a catalyst comprising a sulfided base metal supported on an acidic carrier, thereby converting durene (1,2,4,5-tetramethylbenzene) to isodurene (1,2,4,5-tetramethylbenzene) and prehnitene (1,2,3,4-tetramethylbenzene) and converting pseudocumene (1,2,4-trimethylbenzene) to mesitylene (1,3,5-trimethylbenzene).
