摘要
采用微型反应釜研究了胜利减压渣油、渣油－溶剂（渣油－１－甲基萘）、渣油－供氢剂（渣油－四氢萘）三种体系的热裂化特性，结果表明，供氢剂和溶济对裂化、缩合反应都有抑制作用，延迟生焦诱导期，提高结焦前最大裂化转化率，其中供氢剂对缩合反应的抑制作用大于溶剂作用。反应动力学考察表明，供氢剂可提高反应表观活化能。
By employing micro autoclave, three thermal cracking processes, vacuum residue, vacuum residue 1 methylnaphthalene, vacuum residue tetralin had been studied. The results indicated that hydrogen donor and solvent had suppressing action to both cracked and condensed reaction, enhanced the maximum conversion before coke formation,delayed induction period of coke formation. In addition, hydrogen donor changed the reaction pathways and increased reaction apparent activation energy.
