【摘要】：以國內(nèi)某煉油廠減壓渣油為焦化原料,選用該廠焦化蠟油作為供氫劑,并將焦化蠟油切割成小于400℃餾分(A)、400~430℃餾分(B)和430~460℃餾分(C)3個窄餾分,測定了3個窄餾分的結(jié)構(gòu)參數(shù)和供氫指數(shù),并在相同的反應(yīng)條件下,在減壓渣油中分別摻煉質(zhì)量分?jǐn)?shù)10%的3個窄餾分,考察了各焦化產(chǎn)物的收率,并與純減壓渣油焦化反應(yīng)進(jìn)行了對比。結(jié)果表明:3個窄餾分供氫指數(shù)由大到小的順序為ABC;摻煉窄餾分A的焦化反應(yīng)液體收率明顯高于純減壓渣油焦化反應(yīng);在3個窄餾分中,摻煉A時的液體收率最高,摻煉B時次之,摻煉C時最低,這與3個窄餾分供氫指數(shù)的測定結(jié)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，
