    In a semi-continuous apparatus, Dayan lignite is extracted with water under sub-and supercritical states. The experiments are carried out to investigate effects of the pressure and the final temperature on the extraction yields, and product components. The results indicate that high conversion and extract yield can be obtained by supercritical water extraction of lignite on appropriate conditions. With the increase of the pressure the conversion and the extract yield increase; With the increase of the final temperature the conversion also increases, but the increment is mainly gas and light oil. The main fraction in extract is preasphaltene, and the main gas component is CO2. The extraction residue is a good feedstock for gasification or combustion.

    Investigations are made of heat transfer with supercritical water flowing in inclined tubes. A comprehensive set of data is obtained at pressure from 22. 0 to 28. 0 MPa, mass flow rate from 600 to 1400 kg/(m2· s), he at fluxes from 250 to 410kW/m, and inclinations of 10°and 14°. A new method of calculating two dimensional wall temperature field for non - vertical tubes is presented at the inside wall condition of neither temperature constant nor heat flux constant.

Special heat transfer behavior near the pseudocriti-cal region is analysed. Parameter distribution along the circumference induced by natural convection is also studied.

    In a semi -continuous apparatus, Huangxian lignite was extracted by supercritical water, toluene and their mixture. The effect of different solvents on extraction process was investigated. The results indicated that using toluene as solvent, the conversion and gas yield are lower than using water, but the extract yield is higher. Using water or toluene as solvent, preasphaltene is the dominant fraction in the extract. H/C atom ratio in asphaltene and preasphaltene is higher with water than with toluene, but O/C atom ratio is lower. Results from extraction of Huangxian coal with mixture of water and toluene in different ratio showed that the mixture of 85%~92% water + 15%~8% toluene (w%) is effective for extraction, in which 48.26%~48.71% of extract yield can be obtained.
