PRODUCTION OF AROMATIC HYDROCARBONS FROM METHANE

摘要

IN A PROCESS FOR CONVERTING METHANE TO HIGHER HYDROCARBONS INCLUDING AROMATIC HYDROCARBONS, A FEED (25) CONTAINING METHANE IS CONTACTED WITH A DEHYDROCYCLIZATION CATALYST IN A REACTION ZONE UNDER CONDITIONS EFFECTIVE TO CONVERT SAID METHANE TO AROMATIC HYDROCARBONS. A FIRST PORTION OF THE CATALYST IS TRANSFERRED FROM THE REACTION ZONE TO A HEATING ZONE, WHERE THE FIRST CATALYST PORTION IS HEATED BY CONTACTING THE CATALYST WITH HOT COMBUSTION GASES GENERATED BY BURNING A SUPPLEMENTAL SOURCE OF FUEL. THE HEATED FIRST CATALYST PORTION IS THEN RETURNED TO THE REACTION ZONE.
