【摘要】：以国内某炼油厂减压渣油为焦化原料,选用该厂焦化蜡油作为供氢剂,并将焦化蜡油切割成小于400℃馏分(A)、400~430℃馏分(B)和430~460℃馏分(C)3个窄馏分,测定了3个窄馏分的结构参数和供氢指数,并在相同的反应条件下,在减压渣油中分别掺炼质量分数10%的3个窄馏分,考察了各焦化产物的收率,并与纯减压渣油焦化反应进行了对比。结果表明:3个窄馏分供氢指数由大到小的顺序为ABC;掺炼窄馏分A的焦化反应液体收率明显高于纯减压渣油焦化反应;在3个窄馏分中,掺炼A时的液体收率最高,掺炼B时次之,掺炼C时最低,这与3个窄馏分供氢指数的测定结果一致。
[Abstract]:The vacuum residue of a domestic refinery was used as the coking feedstock, the coking wax oil was selected as the hydrogen donor, and the coking wax oil was cut into three narrow fractions, the distillates (B) and the distillate (C) of 430460C, which were less than 400 鈩，
