Development of coal gasification and gas cleanup technologies in ICC, CAS[Institute of Coal Chemistry, Chinese Academy of Sciences]
Coal is major energy resource in China. In 1997, about 75% of industrial and steam fuel, 65% of chemical feedstock raw material and 65% of the domestic fuel requirements came from coal. And according to the predictions, coal will continue to be the major energy source for the next 30{approximately}50 years. However, coal utilization has caused serious environmental problems, especially where the coal is directly burned. It was indicated from national statistics that in 1998, 70% of the total dust suspension, 80% of the SOx and 75% of the NOx in the air were originated from coal combustion. Today there is a need for China to consider how to meet its needs for increased coal utilization in the way that is cost effective, highly efficient and environmentally friendly. Coal gasification is one of the most efficient and clean coal technologies; it provides syngas for China's chemicals production, industrial fuel gas and town gas. However, the technologies used in China are rather out-of-date, although several units of modern entrained gasifiers are in operation for ammonia synthesis. Based on this situation and the process analysis, the Institute of Coal Chemistry, Chinese Academy of Sciences conducted the research and development of fluidized bed coal gasification technologies. And in order to meet the requirement of advanced power generation system, hot gas cleaning is also studied. This paper presents the status and further studies the planning.
