    摘要: A process for manufacturing a lubricating base oil by: a) performing Fischer-Tropsch synthesis on syngas to provide a product stream; b) isolating from said product stream a substantially paraffinic wax feed having less than about 30 ppm total nitrogen and sulfur, and less than about 1 wt % oxygen; c) dewaxing said feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve comprising a noble metal hydrogenation component, wherein the hydroisomerization temperature is between about 600° F. (315° C.) and about 750° F. (399° C.), to produce an is dimerized oil; and d) hydrofinishing said isomerized oil to produce a lubricating base oil having specific desired properties.

    摘要: A method for producing lubricant base oils is provided comprising the steps of: (a) hydroisomerizing a feedstock over a medium pore size molecular sieve catalyst under hydroisomerization conditions to produce an isomerized product having a pour point of greater than a target pour point of the lubricant base oils; (b) separating the isomerized product into at least a light lubricant base oil having a pour point less than or equal to the target pour point of the lubricant base oils and a heavy fraction having a pour point of equal to or greater than the target pour point of the lubricant base oils and a cloud point greater than the target cloud point of the lubricant base oils; and (c) dehazing the heavy fraction to provide a heavy lubricant base oil having a pour point less than or equal to the target pour point of the lubricant base oils and a cloud point less than or equal to the target cloud point of the lubricant base oils.

    摘要: An improved solid-liquid separation step for use in connection with the Stretford process introduces a small amount of an additive which is then emulsified and mechanically treated in a colloid mill or processed through an air dissolver before introduction into a flotation cell. The process uses dissolved air and/or dispersed air to float the elemental sulfur while simultaneously regenerating the Stretford solution for recirculation.
