摘要： Prior to upgrading a viscous feed by visbreaking, at least a portion of the feed is treated to remove a heavy phase in specified amounts, whereby the severity of the visbreaking may be increased. The Shell Hot Filtration number of the visbreaking product is reduced by at least 75%, compared to visbreaking of untreated feed at some severity.

摘要： A process for the production of gasoline from a light hydrocarbon feed. The feed is catalytically aromatized to produce an effluent containing aromatics and olefins with the aromatics and olefins being subjected to alkylation to produce a gasoline product with a higher octane rating.

摘要： An improved process for the alkylation of benzene in the presence of an alkylation catalyst. The catalyst bed may be caused to move in a direction countercurrent to the movement of the benzene and olefin, or a portion of the catalyst bed is periodically removed and replaced. A regeneration step, whereby the catalyst is heated in a controlled oxygen atmosphere in order to reactivate the catalyst, is also described.
摘要翻译： 在烷基化催化剂存在下烷基化苯的改进方法。 可以使催化剂床沿与苯和烯烃的运动逆流的方向移动，或者催化剂床的一部分被周期性地去除和更换。 还描述了再生步骤，其中催化剂在受控氧气氛中加热以使催化剂再活化。

摘要： In the solvent refining of a residual oil, a mixture of refined oil and refining solvent, and a mixture of pitch impurities and refining solvent are introduced into separate zones of a combination tower operated at a pressure of no greater than 100 psig to recover refining solvent from each of the mixtures. The combination tower is preferably A modified crude distillation tower from a preexisting crude unit, whereby idle crude units may be converted to solvent refining.
