ALKYLATION OF TOLUENE BY METHANOL FOR PRODUCING STYRENE USING LOW SODIUM CONTENT POTASSIUM/CESIUM MODIFIED ZEOLITE CATALYST COMPOSITION

摘要

A process for alkylating toluene (or derivative thereof) with methanol to form e.g. styrene and ethylbenzene (or derivatives thereof) using a modified low sodium content zeolite catalyst composition is disclosed. The zeolite catalyst composition is exemplified by a type X- or Y-zeolite modified with potassium and cesium through a sequential exchange.
