The biomasstomethanol process may play an important role in introducing renewables in the industry chain for chemical and fuel production. Gasification is a thermochemical process to produce syngas from biomass, but additional steps are requested to obtain a syngas composition suitable for methanol synthesis.

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 ...

They proposed to capture CO2 from a coal fired power plant and produce H2 from the water electrolysis. Their results showed that ton of CO2 can be abated per ton of methanol production.

Abstract Methanol production has gained a lot of attention due to its wide application in both the process and product industries. This study aims to investigate the coal/methane based process for simultaneous methanol and power generation. Two process models were developed in Aspen Plus and technoeconomically compared.
Methanol is an important primary chemical product, used as a chemical feedstock for production of a range of important industrial chemicals, primarily acetic acid, formaldehyde, methyl methacrylate and methyl tertiarybutyl ether (MTBE).
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.
Furthermore, flue gas process recycling and treatments, carbon capture and storage (CCS) and other emission and waste purifiers could reduce the burden from coal to methanol production. In [ 19 ], a technoeconomic and environmental assessment was carried out on several current and future methanol production pathways, including steam methane ...
A process for methanol production from natural gas containing 3080% CO 2 was analyzed. For this design a partial feed hydrogenation process is followed by a combined reforming operation and H 2 injection in order to obtain syngas of appropriate quality. A methanol plant of 400,000 t/y that uses a Lurgi reactor for the synthesis reaction, was ...
Although some is still produced from old and inefficient coal gasification plants, Methanol is mainly produced in areas of the world where a large supply of Natural Gas is available at an economical supply cost.
The coaltomethanol (CTM) is an important technical route for methanol production. The process suffers from high CO2 emission and low energy efficiency due to the mismatch of H/C (hydrogentocarbon) ratio between raw coal and products. Hydrogen production from renewable energy can be introduced into the system to meet the H/C ratio.

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.
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.
