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.

Conventionally, methanol is produced on industrial scale from synthesis gas "syngas," which is a combination of varying amounts of H 2, CO, and CO 2 frequently derived from gasified coal or natural gas ( Ott et al., 2012; Sheldon, 2017 ).

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 ...

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.

Methanol is an important feedstock of chemical engineering and energy source, and it is mainly produced by coal route in China. The coaltomethanol suffers from serious CO 2 emissions and carbon resource waste since water gas shift is involved in this process to increase hydrogen content of syngas for meeting methanol novel coaltomethanol process integrated with cokeoven gas ...
