A methanol, olefin, and hydrocarbon synthesis process

摘要

An improved method for the production of methanol and hydrocarbons from a methane-containing gas, such as natural gas. The improved method integrates a hydrocarbon synthesis unit with a methanol synthesis unit. The invention combines a syngas stream from a steam reformer, a syngas stream from an oxidation reformer and additional carbon dioxide to form an optimal syngas composition that is directed to a methanol synthesis reactor. The invention also integrates other process parameters and process components of a methanol and hydrocarbon synthesis process plant to effectively convert most of the carbon in the natural gas to commercial-value products. The invention is also directed to a method of making olefin from the methanol produced by the process of the invention.
