There is a process for the production of methanol from gaseous hydrocarbons. The process has the following stages: (a) treating said gaseous hydrocarbons in a desulfurization unit to produce a desulfurized hydrocarbon gas; (b) reacting the desulfurized gas with an oxidizing flow by means of a short contact time partial catalytic oxidation reaction to produce synthesis gas; (c) producing hydrogen by electrolysis of water; (d) mixing and compressing synthesis gas and hydrogen; and (e) sending said compressed mixture to a methanol synthesis unit to produce methanol.

A process for preparing methanol from carbon dioxide and hydrogen in a methanol synthesis unit and working up the reaction mixture obtained stepwise to isolate the methanol, wherein the carbon dioxide, carbon monoxide, dimethyl ether and methane components of value from the streams separated off in the isolation of the methanol from the methanol reaction stream are combusted with an oxygenous gas, and the carbon dioxide in the resultant flue gas is separated off in a carbon dioxide recovery unit and recycled to the methanol synthesis unit.

A system and a method for methanol production is described. The method includes gasifying coal to produce a coal gas comprising hydrogen and carbon monoxide; transferring heat from the coal gas to a natural gas reforming mixture including water and methane; reforming the natural gas reforming mixture to form a reformed natural gas; mixing the coal gas, the reformed natural gas, and a recycled gas including hydrogen and carbon monoxide to form a synthesis gas; reacting the synthesis gas to form methanol and a waste gas; separating the methanol and the waste gas; removing hydrogen from the waste gas to produce a dehydrogenated waste gas; and subjecting the dehydrogenated waste gas to a water-gas shift reaction to produce the recycled gas.

A process for the production of syngas, the process comprising (i) reacting at least a portion of carbon dioxide with hydrogen within an initial reactor to produce an initial product stream including carbon monoxide, water, unreacted carbon dioxide, and unreacted hydrogen; and (ii) reacting at least a portion of the unreacted carbon dioxide and unreacted hydrogen within a reactor downstream of the first reactor to thereby produce a product stream including carbon monoxide, water, unreacted carbon dioxide, and unreacted hydrogen.
