Coal gasification is the process that changes coal into a gas that has the same heating value as natural gas and that is cleaner than burning coal itself.

The process of converting coal into gas. The basic process involves crushing coal to a powder, which is then heated in the presence of steam and oxygen to produce a gas. The gas is then refined to reduce sulfur and other impurities. The gas can be used as a fuel or processed further and concentrated into chemical or liquid fuel.

The chemical conversion of coal to synthetic gaseous fuels.

The heating and partial combustion of coal to release volatile gases, such as methane and carbon monoxide; after pollutants are washed out, these gases become efficient, clean-burning fuel.

A chemical process converting coal to a gas that can then be used in place of natural gas.

The chemical conversion of coal to synthetic gaseous fuel.

The conversion of coal to a gas that can be processed to produce synthetic fuels such as natural gas.

Conversion of coal to a gaseous product by one of several available technologies.

The conversion of coal into a gaseous fuel.

Conversion of solid coal to synthetic natural gas (SNG).
