Status and Progress of Coal Prolysis and Conversion to Valuable Chemicals

The technology of coal pyrolysis and conversion to valuable chemicals is important in utilizing coal resource efficiently and clearly, which is significant from the viewpoints of both theoretical researches and industrial applications. In this paper, the research status and progress of coal pyrolysis and utilization have been reviewed, technologies of coal flash pyrolysis, oriented catalytic conversion and producing valuable chemicals from coal pyrolysate were focused. By analyzing the advantages and disadvantages of existed technologies for utilization of coal, a new approach was proposed to utilize coal not only as energy resource but also as chemical resource. Some novel technologies such as supercritical extraction, reaction and separation in medium of ionic liquid, catalytic conversion of multicomponents mixture to a few key components, simulation and optimization of integrated co-production system of coal were suggested. The new approach proposed in this paper may provide new opportunities to utilize coal efficiently.
