EFFECT OF COAL-SWELLING AND SYNCHRONOUSLY SUPPORTED CATALYSTS ON COPROCESSING OF BITUMINOUS COAL AND HEAVY OILS
摘要
Abstract
Fe(NO3)3 as catalytic precursor and Na2S as in-situ presulfurizer were impregnated on the Shenhua bituminous coals which were synchronously swollen with H2O, methanol, N-N dimethylformamide (DMF) or dimethyl sulfoxide(DMSO) at 20 'C for 12 h. Then the swollen coals were prepared by vacuum drying. The co-processing of swollen Shenhua coal and two heavy oils(LGAR and Du84) was carried on under the condition of the mass ratio of 2:1 oil to coal, 8 Mpa cold hydrogen pressure,420℃ and 1 h. The coprocessing of the swollen bituminous coal and LGAR or Du84 was significantly improved on the coal liquefaction. Among the three swelling solvents, the improvement of DMF was the highest, that of DMSO was the better and methanol were the lowest. Du84 was favor in the coprocessing than LGAR. By XRD analysis, the iron catalysts on the swollen coal with Fe(NO3)3 synchronously impregnated with the solvents were amorphous and highly dispersed on coal surface and could transform into Fe1-x S in the coprocessing. During the coprocessing, the deactivation of the catalyst synchronously impregnated on swollen coal with DMF was not clear.关键词
