The production of methanol from coal holds unique potential as a means of using a technology which is commercially available for producing a versatile fuel that can be used in automobiles, electric power plants, gas turbines, and fuel cells, A methanol-from-coal process involvesgasification of coal to produce synthesis gas (carbon monoxide and hydrogen), followed by catalytic conversionto produce methanol.
People also ask
How is methanol made from natural gas?
On an industrial scale, methanol is predominantly produced from natural gas by reforming the gas with steam and then converting and distilling the resulting synthesized gas mixture to create pure methanol.
What is the process of converting coal to methanol?
Block diagram of coal-to-methanol process. First, coal is pre-processed by methods such as crushing, sizing and drying to prepare it for the coal gasification process. A coal source must be selected between Martin Lake Texas Lignite, Montana Sub-Bituminous, and Illinois #6 Bituminous.
What is the difference between methanol and synthesis gas?
This methanol production pathway is a fossil fuel base process and can dramatically result in the emissions of GHGs. On the other hand, synthesis gas is a valuable product and requires an extremely complex process for production. Therefore, an alternative feed for methanol production is necessary.
Is methanol production from CO2 a good idea?
According to Olah (2005), methanol production from CO 2 is favorable not only for the use of nonfossil fuel sources (unlike syngas), but also because it allows the avoidance of CO 2 sequestration, which is a very expensive process, and offers mitigation of the greenhouse effect by means of an efficient recycling of CO 2.
