摘要： A storage-stable modified asphalt composition, which comprises: 50-97.7 parts by weight of a base asphalt, 2.0-20.0 parts by weight of a polymer having double bonds, 0.1-20.0 parts by weight of a compatibilizer, 0.1-10.0 parts by weight of a cross-linking reagent, and 0.1-10.0 parts by weight of a organic polar compound, and the softening point difference of its product determined by the stability test is lower than 2.5° C. The process for preparing said modified asphalt composition is mixing 50-97.7 parts by weight of a base asphalt, 2.0-20.0 parts by weight of a polymer having double bonds, 0.1-20.0 parts by weight of a compatibilizer 0.1-10.0 parts by weight of a cross-linking reagent, and 0.1-10.0 parts by weight of a organic polar compound under certain conditions. The modified asphalt provided by the present invention has good storage-stability. The preparation process provided by the present invention is simple, and there is no need for special apparatus.

摘要： A combined process of low degree solvent deasphalting and delayed coking, which comprises feeding a deasphalting stock and a solvent into an extractor and making the yield of the deasphalted oil 70 wt %-95 wt %, and introducing a part or all of the deasphalted oil and optionally a conventional coking stock into a delayed coker. This process increases the yield of liquid products, removes the heavy asphaltene which is prone to coke, extends the run length of the delayed coker, and at the same time, lowers the content of impurities in coke, enlarges the sources of the stocks for producing the needle coke.
