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.

1. A method for making methanol comprising:directing a methane containing gas and steam to a steam reformer to form a first syngas stream and directing at least a portion of the first syngas stream to a methanol synthesis reactor; directing a methane containing gas and oxygen to a partial oxidation reformer to form a second syngas stream and directing at least a portion of the second syngas stream to the methanol synthesis reactor; and directing at least a portion of the second syngas stream to a hydrocarbon synthesis reactor; wherein the portions of the first and the second syngas streams directed to the methanol synthesis reactor yield a combined syngas stream having a syngas number of from 1.4 to 2.6.
