· The hydrogen to carbon (H/C) ratio of coal gasified gas ranges of, far less than the desired value for the coal to methanol process. Therefore, a water gas shift (WGS) unit is needed to raise the H/C ratio, which results in a great deal of CO 2 emission and carbon resource waste. On the other side, in the coking process, massive cokeoven gas (COG) is not been fully used, with a high H ...
· Coking coal is the main ingredient in the steel manufacturing process. Around 770kg of metallurgical coal is required to manufacture nearly one ton of steel. Steel can be produced via two main processes, electric arc furnace (EAF) or through blast furnacebasic oxygen furnace (BFBOF).
Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth's crust. Categories of met coal include hard coking coal, semihard cokingcoal, semisoft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.
