摘要： Improved additives for motor fuels and lubricants are provided comprising low molecular weight hydrogenated liquid polymers containing low levels of combined nitrogen. More specifically, hydrogenated adducts formed from normally liquid low molecular weight polydiolefins and acrylonitrile are excellent additives for motor fuels and lubricants. Motor fuels and lubricating oil compositions containing said additives are also provided.

摘要： Organically polluted waters are purified by contacting such waters with a water soluble copper salt catalyst in the liquid phase under oxidizing conditions. In one embodiment, an aqueous stream obtained from the effluent of an oxidative dehydrogenation process containing contaminating oxygen-containing organic materials is subjected to liquid phase oxidizing conditions in the presence of cupric nitrate under conditions providing sufficient cupric ion concentration to convert the water to a potable aqueous product.

摘要： A lube-oil range hydrocarbon mixture is produced by the oligomerization of a branched olefin mixture which contains olefins of 6 to 16 carbon atoms and has a degree of branching of about 10 to 50 mole percent of branched olefins; the lube-oil range hydrocarbon is obtained by separating and hydrogenating the oligomerized olefins.

摘要： Internal olefins such as those obtained from a disproportionation of 1-olefins like 1-decene are dimerized over a promoted boron trifluoride catalyst to yield oils useful as lubricant basestock.

摘要： A heavy gasoline fraction having a relatively low research octane number as for instance a fraction obtained from a cat cracker gasoline is passed over a chlorided alumina catalyst modified by the addition of 0.01 to 5 weight percent lead calculated as PbO. The presence of lead decreases the cracking activity of the catalyst so that it can be operated at a higher temperature which favors increased formation of aromatic hydrocarbons.
摘要翻译： 具有相对低的研究辛烷值的重汽油馏分，例如从猫裂解汽油获得的馏分，通过加入以PbO计算的0.01至5重量百分比的铅改性的氯化氧化铝催化剂上。 铅的存在降低了催化剂的裂解活性，使得其可以在有利于增加芳族烃形成的较高温度下操作。

摘要： A mixed olefin feedstock obtained from disproportionating C.sub.8 -C.sub.10 1-olefins can be used as such, i.e. without removal of 1-olefins in a boron trifluoride catalyzed dimerization step to produce synthetic lubricating oils. The results achieved are as good as those achieved using a feedstock from which the undisproportionated 1-olefins have been removed so that this feedstock contains only internal olefins for the dimerization.
摘要翻译： 可以使用从歧化C8-C101-烯烃得到的混合烯烃原料，即在三氟化硼催化的二聚步骤中不除去1-烯烃，以生产合成润滑油。 所获得的结果与使用未分配的1-烯烃已经除去的原料所达到的结果一样好，使得该原料仅含有用于二聚化的内烯烃。
