沙轻减渣与油浆丁脱沥青制备高等级道路沥青的研究

STUDY OF BUTANE-DEASPHALTED MIXTURE OF SAUDI ARABIA LIGHT CRUDE OIL VACUUM RESIDUE AND FCC SLURRY PRODUCING HIGH GRADE PAVING ASPHALTS

溶剂脱沥青是一种有效的渣油深加工工艺。本文对沙轻减渣与催化裂化油浆的混合物的脱油沥青调和重交沥青的可行性进行了研究。结果表明：沙轻减渣与催化裂化油浆混合物溶剂脱沥青得到的脱油沥青与减渣可以调和出各种牌号的高等级道路沥青。

Residue solvent deasphalting is an important technology for residue processingDisclosed in this paper is a study for producing high grade paving asphalts from butane-deasphalted mixture of Saudi Arabia light crude oil vacuum residue and FCC slurryThe results indicate that the deasphalted part blends with Saudi Arabia light crude oil vacuum residue can produce good property high grade paving asphalts
