Now,Chinas energy pattern is rich in coal,less in gas and lack of oil; Therefore,the development of coal chemical industry,especially coal-based feedstock gasification technology has a very high competitive advantage.Compared with the traditional dry gas hydrogen production and naphtha hydrogen production,the hydrogen plant process of entrained flow gasification cost lower,nearly 20% -30%;The higher the price of crude oil,the competitive advantage of coal-based hydrogen production of raw materials is more obvious.
