Present situation analysis and prospect of low rank coal quality-based utilization conversion route

In order to know systematically the products' application status and the trends of technology developmentoflow rank coal quality-based utilization in China,introduces the process route and conversion path of low rank coal quality-based utilization briefly,and expounds the three main products (coal tar,pyrolysis gas,carbocoal) produced by pyrolysis and their industrial application status.Emphatically sumed up how to use coal tar,pyrolysis gas and carbocoal,and analysed the key technology problems of low rank coal quality-based utilization at present,put forward the research directions in future,also on the development prospects were looking forward.Through the analysis,that according to the distribution of coal resources in China,reserves and characteristics of low rank coal,as well as the guidance of the national to the coal energy policy,in conditions of solving the common key problems,low rank coal quality-based utilization should be taken as the upstream process,at the same time,downstream of coal-electricity-chemical industry integration project,this park project group mode forthe clean coal quality-based utilization will be the best way to achieve mutual benefit and win-win use of low rankcoal.
