摘要: 在微型高压釜中研究了克拉玛依常压渣油（KLAR）和辽河减压渣油（LHVR）的饱和分、芳香分在分散型催化剂作用下的临氢热反应行为并计算其动力学参数。结果表明，饱和分与芳香分主要发生裂化反应，生成石脑油与柴油馏分，不会生成甲苯不溶物，极少量的芳香分缩合生成沥青质。在相同的反应苛刻度下，KLAR与LHVR饱和分裂化和缩合产物产率没有明显的差别，而KLAR芳香分的裂化产物产率略高于LHVR芳香分，而其缩合产物产率略低于LHVR饱和分。Abstract: This study focused on the thermal reaction of saturate and aromatics components of Karamay atmospheric residue (KLAR) and Liaohe vacuum residue (LHVR). The reactions were carried out in a micro autoclave with dispersed-phase catalyst under hydrogen atmosphere, and then the thermal reaction kinetic parameters were calculated. Saturate and aromatics were mainly cracked into naphtha and diesel oil fraction without toluene insoluble(TI) during thermal reaction, and a considerable part of aromatics condensed into resin, and further asphaltene. At same reaction conditions, the yields of cracking products and condensation products between KLAR-saturate and LHVR-saturate were not different, but the yields of the cracking products of aromatics in KLVR was slightly higher than that of LHVR, and the yields of the condensation products of aromatics in KLVR was a little lower than that of LHAR.
