Conversion of coal from its solid form to a gaseous fuel (or, gaseous chemical) is widely practiced today. During earlier years (), coal gasification was being employed to produce manufactured gas in hundreds of plants worldwide, and such plants were called manufactured gas plants (MGPs). This technology became obsolete

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coaltomethanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO2 from the gasification plant by implying process intensification. The base case and ...

In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
