Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (C H 3 O H) is less expensive to produce sustainably than ethanol fuel, although it produces more toxic effects than ethanol and has lower energy density than gasoline. Methanol is safer for the environment than gasoline, is an antifreeze agent ...

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).
Manufacture of methanol (a) Production of synthesis gas (i) Traditional methods. Methanol is manufactured from synthesis gas which is a mixture of carbon monoxide and hydrogen. The feedstock, over the last 40 or more years, has been oil or natural gas. Coal, particularly in China, coal, rather than natural gas or oil, is being used as the ...
• Production from coal only takes place in China and has a high carbon footprint, of nearly 300 g CO 2eq/MJ, due to large emissions associated with both the mining of coal and the methanol conversion process. • Production from renewable sources, such as from biomethane, solid biomass, municipal solid waste (or MSW, which contains a considerable

Methanol can be produced from coal via gasification and methanol synthesis technology [5]. Coal is partly gasified with oxidizing agents, and the volatile components are converts to syngas [6].
Since methanol can be produced from biomass, numerous countries could produce and utilize biomethanol. Here, we review methanol production processes, technoeconomy, and environmental viability. Lignocellulosic biomass with a high cellulose and hemicellulose content is highly suitable for gasificationbased biomethanol production.
Gasification of coal, in addition to generating syngas for power production, has the potential to produce a diverse array of highvalue products. It is a challenge to understand the optimal use of this domestic coal resource amidst the potential technology options, product slates (including coproduction of power), and competing feedstocks ...

Methanol is a low carbon, hydrogen carrier fuel produced from high ash coal, agricultural residue, CO2 from thermal power plants and natural gas. It is a colourless liquid that boils at °C and solidifies at − °C . It forms explosive mixtures with air and burns with a nonluminous flame. It is completely miscible in water.

Process Design and Analysis of Aromatics Production from Coal via Methanol with a High Yield. Producing aromatics from coal via methanol is a novel technology, which could mitigate the energy shortage in a petroleumpoor area. However, the selectivity of methanol to aromatics is merely 4070 wt % due to the byproducts of light hydrocarbons.
In fact, methanol synthesis is the second source, after ammonia production, of hydrogen consumption (which has the highest energy content per weight) via several reactions, such as partial oxidation, steam reforming, autothermal reforming, methanol decomposition, or methanolwater solution electrolysis.
Gao et al. (2018) identified that the coaltomethanol production process consumes vast amounts of energy and water with significant emissions of GHGs. Lerner et al.
