Coal Gasifiion. As early as 1800, coal gas was made by heating coal in the absence of air. Coal gas is rich in CH 4 and gives off up to kJ per liter of gas burned. Coal gas or town gas, as it was also known became so popular that most major cities and many small towns had a local gas house in which it was generated, and gas burners were adjusted to burn a fuel that produced kJ/L ...
This paper generalizes the achievements of coal processing and comprehensive utilization in China. However, some of the phenomenous at present are also pointed out, such as low coal washing rate, coking is mainly technology in coal conversion and lay stress on coking and look down on chemical products processing et al. Obviously, the deep processing of coal use is very weak.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Feb 12, 2015 · The hydrogen to carbon (H/C) ratio of coal gasified gas in the range –, far less than the desired value for the coal to methanol process. Therefore, a water gas shift unit is needed to raise the H/C ratio, which results in a great deal of CO2 emission and carbon resource waste. At the same time, there is 7 × 1010 m3 cokeoven gas (COG) produced in coke plants .
