MODIFIED ZEOLITE CATALYST COMPOSITION AND PROCESS FOR ALKYLATING TOLUENE WITH METHANOL TO FORM STYRENE

摘要

A modified zeolite catalyst composition and process for using the catalyst composition to alkylate toluene for derivative thereof) with methanol to form e.g. styrene and ethylbenzene for derivatives thereof) is disclosed. The catalyst composition is exemplified by a type X- or Y-zeolite modified with (1) at least one alkali metal selected from Cs, K, and Rb; (2) at least one metal selected from Mn, Fe, Cu, and 2n; and (3) boron and/or phosphorus.
