摘要： The invention discloses that hydrocarbon lubricants containing olefinic unsaturation participate in an olefin metathesis reaction with alkenes containing polar functional groups to provide an equilibrium mixture containing hydrocarbon lubricants containing the polar groups of the alkenes. The discovery is particularly applicable to the functionalization of near linear lubricants prepared from the oligomerization of propylene using surface deactivated zeolite or lubricants prepared by the oligomerization of C.sub.6 -C.sub.20 alpha olefins using coordination catalyst. Functionalized groups can be incorporated that impart a wide range of properties to the lubricant such as anti-wear or anti-corrosion resistance, or improve the compatibility of the lubricant with other additives.

摘要： Olefin upgrading in plural reactors can achieve conversion of lower olefinic feedstock, such as propene, butene, etc., to valuable heavy hydrocarbons containing a lubricant fraction of high viscosity index. Other fuel products, such as (C.sub.10 -C.sub.20) distillate, gasoline and LPG may also be recovered as products. In a preferred process for converting lower olefinic feed to heavier hydrocarbons by contacting the feed with a shape selective medium pore acidic zeolite catalyst at elevated temperature and pressure the catalyst surface is rendered relatively inactive by adding to the olefinic feed an inactivating amount of a sterically-hindered organic base, whereby the catalyst is selectively surface-deactivated, to produce substantially linear heavier hydrocarbons rich in C.sub.10.sup.+ olefins. In the preferred multi-stage process the olefinic feed comprises C.sub.2 -C.sub.8 olefins and the catalyst employed in each stage comprises aluminosilicate having a silica-to-alumina mole ratio of at least 12 and a constraint index of about 1 to 12.
摘要翻译： 在多个反应器中的烯烃升级可以实现将低级烯烃原料如丙烯，丁烯等转化成含有高粘度指数的润滑剂部分的有价值的重烃。 其他燃料产品，如（C10-C20）馏出物，汽油和LPG也可作为产品回收。 在优选的方法中，通过使进料与形状选择性中孔孔酸性沸石催化剂在升高的温度和压力下接触来将低级烯烃进料转化成较重的烃，通过向烯烃进料中加入灭活量的空间位阻，使催化剂表面相对无活性， 受阻的有机碱，其中催化剂被选择性地表面失活，以产生富含C10 +烯烃的基本上线性的较重的烃。 在优选的多级方法中，烯烃进料包含C 2 -C 8烯烃，并且在每个阶段中使用的催化剂包含二氧化硅与氧化铝的摩尔比至少为12，约束指数为约1至12的硅铝酸盐。
