methanol (CH 3 OH), the simplest of a long series of organic compounds called alcohols, consisting of a methyl group (CH 3) linked with a hydroxy group (OH). Methanol was formerly produced by the destructive distillation of wood. The modern method of preparing methanol is based on the direct combination of carbon monoxide gas and hydrogen in the presence of a catalyst.

The current global capacity of methanol production is 164 Mton·a º1 (year 2021), with an annual increase of 10% projected for the next decade [10]. Traditionally, methanol synthesis is fed by fossilbased syngas, which comes either from steam reforming of natural gas or from coal gasifi cation [11]. However, sustainable syngas

How is Methanol Produced? While today we produce methanol from natural gas, methanol can also be made from renewable sources, such as renewable natural gas, biomass and green hydrogen combined with recycled carbon dioxide. Methanex is studying the feasibility of converting our existing assets to produce lowercarbon intensity methanol. We are committed to pursuing opportunities [.]

Methanol can be used to make a gasoline product. The process uses a special zeolite catalyst with pore size such that molecules up to C10 can get out of the catalyst. Larger molecules cannot be made with this process; therefore, a product is made with no carbon molecules greater than C10, which boils in the gasoline range.
