摘要

在微型反应管中

以神华煤液化残渣为原料，四氢萘为溶剂，在氢初压6 MPa、反应温度425～485℃、反应时间为0～30 min条件下，进行了煤液化残渣加氢实验，研究了煤液化残渣的加氢动力学特性。将氢化产物分为油气、沥青质和四氢呋喃不溶有机质，根据集总概念建立了煤液化残渣的加氢动力学模型，所建模型与实验值吻合程度高。在实验条件下，四氢呋喃不溶有机质向沥青质转化的活化能为147.41 kJ·mol-1

沥青质向油气转化的活化能为34.81 kJ·mol-1，沥青质缩合为四氢呋喃不溶有机质的活化能为173.48 kJ·mol-1。

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.
