Coal Transportation Since the distance between the energy supply point and the energy demand point for coal is often long, many coal utilization projects require that transporta tion technology and costs be considered. For long distances the cost of transpor tation can greatly exceed the mining cost. As the nation uses and exports greater
Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)–from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for municipal lighting, and heating ...

enriched coal (13), so utilization of the magnetic fraction of fly ash in coal processing could provide a substantial market. The heavymedia material used today is either natural magnetite or manufactured fer rosilicon particles. They sell for 100 per metric ton or more. There also may be applications for magnetic fly ash as a seed material
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 annually in China.
This manuscript developed two methodologies of mapping energy flows of coal utilization in the form of Sankey diagrams: one was energy allocation diagram without illustrating any energy losses and the other was energy efficiency diagram illustrating main energy losses. Based on the methodologies, energy flow diagrams of China's coal utilization in the year 2005 and 2010 were presented.

Abstract. Coal is one of the major energy resources in China, accounting for approximately 70 % of primary energy consumption. Many environmental problems and human health risks arise during coal exploitation, utilization, and waste disposal, especially in the remote mountainous areas of western China (, eastern Yunnan, western Guizhou and Hubei, and southern Shaanxi).

Coal Coal Coal types: Coals contain both organic and inorganic phases. The latter consist either of minerals such as quartz and clays that may have been brought in by flowing water (or wind activity) or of minerals such as pyrite and marcasite that formed in place (authigenic). Some formed in living plant tissues, and others formed later during peat formation or coalification.
