中文摘要：

通过含大量沥青质的煤液化残渣在微型反应釜的加氢实验,考察了温度、气氛、H2初压以及反应时间对煤液化残渣中油（Oil）、沥青质（PAA）和四氢呋喃不溶有机质（THFIS）加氢性能的影响。结果表明,煤液化残渣中的PAA和THFIS可进一步加氢转化成Oil,煤催化液化残渣与煤非催化液化残渣中的PAA最高转化率分别为77.43%和80.54%;N2压的存在能促进煤液化残渣中THFIS转化成PAA,高压H2有利于THFIS和PAA加氢转化成Oil。煤催化液化残渣和煤非催化液化残渣的最佳的加氢温度均为450℃,最佳的H2初压均为6 MPa,最优的反应时间分别为60 min和30 min。

英文摘要：

In order to study the effects of temperature, atmosphere, initial hydrogen pressure, as well as reaction time on the hydrogenation of the oil fraction（Oil）, asphaltene fraction（PAA） and tetrahydrofuran insoluble organic matter fraction （THFIS） in coal liquefaction residue, the hydrogenation of asphaltene-rich coal liquefaction residue was investigated by a micro-reactor. Results indicated that PAA and THFIS could be further hydrogenated into Oil. The maximum conversion rates of PAA in coal catalytic liquefaction residue and coal non-catalytic liquefaction residue were 77. 43% and 80. 54%, respectively. N2 pressure could promote the conversion of THFIS to PAA, but it could not promote the conversion of the PAA to Oil; and higher H2 pressure could help the hydrogenolysis of PAA and THFIS to produce Oil. The optimal temperature and initial pressure H2 for hydrogenolysis of coal catalytic liquefaction residue and coal non-catalytic liquefaction residue were 450℃ and 6 MPa, the optimal reaction time were 60 min and 30 min, respectively.
