Methanol produced from coal. Methanol syngas production from coal is mainly based on the intermittent gasification process in the fixedbed reactor. (Tatarczuk et al., 2010, Wei et al., 2009). The primary syngas from the fixedbed reactor has a lower ratio of hydrogen to carbon, which hardly be employed to produce methanol.

Novel coaltomethanol process with nearzero carbon emission ...

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.

Methanol fuel Wikipedia

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 ...
