Synthetic gas from hard coal is a gaseous mixture obtained by coal gasification, primarily composed of carbon monoxide (CO), hydrogen (H2), and other components such as methane (CH4). The production process of synthetic gas involves various gasification technologies, including fixed-bed, fluidized-bed, and entrained-flow gasification. These technologies have different requirements for the quality of the feedstock coal and vary in technological maturity and advancement. This product can be used for the production of various chemicals and fuels.
