Abstract: Based on a coal indirect liquefaction (coal to oil) plant with four million ton of coal per year as a model, taking the coal-fired power generation of the mos t wide applied coal utilization accesses as the references, from the coal comprehensive energy efficiency, solid waste treatment and recovery utillzation, water consump tion, waste water treatment and drainage, SO2 treatment and emission, CO2 collection and sealing, and others, the energy efficiency and environment feasibility of the coal indirect liquefaction were analyzed.The analysis showed that the coal indirect liquefaction would be a new access with higher energy efficiency and more clean coal utilization and could provide the references to the CO2 collection, sealing and uillization in the future.
