Coal chemical is defined as producing chemical products with coal as main raw material.Based on different production processes and product varieties,coal chemical is classified into three product chains of coal coking,coal gasification and coal liquefaction.With the surging price of oil,the large-scale coal chemical pro-duction using coal gasification technol-ogy has become a global trend.The inte-gration of energy and chemical can reduce a dependence on oil resources and effec-tively cut down pollution and emission in energy-consuming sectors such as com-munication and coal-fired power Coal chemical is defined as producing chemical products with coal as main raw material.
