随着经济的发展，国内对优质液体燃料的需求日趋增加，预计今后供需矛盾将更为突出。中国能源资源的特点是油少煤多，若对较年轻的煤种采用快速热解和快速冷凝的拨头工艺，并与循环流化床锅炉相结合，可望获得较高的油品收率，同时实现煤的洁净燃烧。而研究和开发一种新型的热解反应器是实现新工艺工业化的关键课题。

关键词： 煤拔头;热解急冷;液体产品

The characteristic of energy resources in China is less in oil and more in coal. The demand of high quality liquid fuels is ever increasing in China with its economic development. It is expected that the relation between supply and demand will become a serious problem in the future. By use of a new process of coal topping,which combines quick pyrolysis-quenching with a circulating fluidized bed combustor，a higher oil recovery can be obtained for young coal , and coal clean combastion will be realized. Developing a new type of pyrolysis reactor is a key step for industrialization of the new process.

Key words: coal topping;pyrolysis-quenching;liqulid products
