摘要: |
The hydrogenation of coal under mild conditions is an important step for the stepwise coal liquefaction process. Clear understanding of the characteristics of the coal liquefaction under the mild condition and the structure properties of the corresponding heavy products is desired for development of the methods that may predict and control the extent of the process. The characteristics of hydro-liquefaction of three lower rank coals (one sub-bituminous coal and two lignite samples) under mild conditions (1-5MPa pressure and 250-450oC) were studied. The structure properties of the corresponding heavy products were investigated by means of GPC, FTIR, CWSFS and TPD/FID&FPD. The reaction temperature and the properties of solvent were found to be two crucial important factors. If these two factors are properly selected, it is possible to run the reaction under lower H2 pressure or even inert gas pressure without use of expensive catalyst and to meet the requirements for the next step. It may be achieved that obtaining coal liquids and upgrading the gasification reactivity of the lower rank coal in the same time. |
