COAL DEVELOPMENT TREND WITH THE ADVANCE OF RESEARCHING AROMATIC POLYMERS

Coal is the main fossil resources and energy,but meanwhile it is also a main pollution source in China.Coal,of which document posittion as energy sources will elapse forever,is forcing challenges of petroleum,natural gas and new energy sources.Main chain type aromatic polymers are now invoking more and more interests because of their many advantages,such as good thermal stability,chemical stability,low density but robustness and facility to process,but their wider application is limited by the preparation of aromatics which are rich in coal.This provides a new opportunity and way for the development of coal.Preparation of the special chemicals from coal should be an important subject of coal chemical engineering.
