神华煤液化残渣的加氢反应动力学
Hydrogenation kinetics of Shenhua coal liquefaction residue
摘要
Abstract
The hydrogenation kinetics of Shenhua coal liquefaction residue was studied in a microreactor. The experiment was carried out at reaction temperatures from 425℃ to 485℃ and reaction time from 0 min to 30 min with 6 MPa hydrogen pressure. The product was divided into three types, oil and gas (Oil+G), preasphaltene and asphaltene (PAA) as well as tetrahydrofuran-insolubles (THFIS). A model to describe the hydrogenation of Shenhua coal liquefaction residue was proposed. Results indicated that the proposed model can predict well the conversions to the three types of products. The activation energies of THFIS to PAA, PAA to Oil + G and PAA to THFIS were calculated as 147. 41, 34. 81 and 173. 48 kJ ·mol~(-1), respectively.关键词
