Study on Catalytic Thermal Dissolution of lignite and Hydro-liquefaction of Its Thermal Dissolution Soluble Fraction For Potential Jet Fuel
Keyworlds: Xilinguole lignite; Catalytic thermal dissolution; Hydrogenation liquefaction; Catalyst; Jet fuel
The effects of different catalysts on the catalytic thermal dissolution (TD) properties of Xilinguole (XLGL) lignite were studied. The structure of thermal dissolution soluble fractions (TDSFs) was analyzed and characterized. The results suggest that the catalytic activity of the four catalysts used is in order of BF3/SBA-15＞FeS+S＞SO42-/ZrO2=Fe2O3. At 360℃, the TD yield of BF3/SBA-15 was the highest, and the TD yields of CMNO, 1-MN+10%CH3OH and 1-MN were 39.5%, 59.6% and 28.6%, which were higher of 17.1%, 17.4% and 12.7% than those without catalyst respectively. The results suggest that the catalyst can improve TD activity of lignite.
The TDSF obtained with 1-MN+10%CH3OH and BF3/SBA-15 catalytic TD at 360℃ gave the highest yield of liquefied oil (CHS) as 33.1% after catalytic hydrogenation under Ni-Mo-S/Al2O3 with cyclohexane as solvent at 360℃. This is because the aromatic condensation degree of this TDSF is lower and the aliphatic hydrocarbon content is higher, which is beneficial for the hydro-liquefaction of TDSF. CHSs obtained by liquefaction of TDSF from the catalytic TD of lignite in 1-MN were dominated by 1~2 ring aromatic compounds. The content of saturated cycloalkanes in CHS obtained by liquefaction of TDSF at 320℃ was 6.12%, which was slightly higher than that of 5.07% in CHS obtained by liquefaction of TDSF at 360℃.
The hydroliquefaction activity of three catalysts used were in the order Ni-Mo-S/Al2O3>Ni/ZSM-5>Cu-Ni/Al2O3. In the presence of catalyst Ni-Mo-S/Al2O3 and tetrahydronaphthalene as hydrogen donor solvent, the yield of CHS increased gradually with the increase of the liquefaction temperature from 280℃ to 400℃, and the maximum was 60.4% obtained at 400℃. The content of saturated cycloalkanes in CHS decreased with the increase of liquefaction temperature, and the maximal content of saturated cycloalkanes in CHS was 13.5% obtained at 280℃, suggesting that low temperature hydrogenation is favorable to saturate hydrogenation of aromatics. Therefore the hydro-liquefaction of TDSF at low temperature can be used to produce the potential jet fuel.
