    摘要: An integrated process for lowering the pour point of Fischer-Tropsch derived wax which comprises (a) collecting separately from a Fischer-Tropsch unit a Fischer-Tropsch wax and a Fischer-Tropsch condensate; (b) pyrolyzing the Fischer-Tropsch wax in a thermal cracking zone under thermal cracking conditions pre-selected to achieve a cracking conversion of the paraffins molecules present in the Fischer-Tropsch wax of at least 10 percent; (c) recovering from the thermal cracking zone a low pour point Fischer-Tropsch derived wax and a Fischer-Tropsch derived overhead product; and (d) mixing at least a portion of the Fischer-Tropsch derived overhead product recovered in step (c) and at least a portion of the Fischer-Tropsch condensate collected in step (a) with at least a portion of the low pour point Fischer-Tropsch derived wax in the proper proportion to produce a Fischer-Tropsch derived waxy product having a pour point equal to or below about 40 degrees C.

    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 process for producing a lubricant bright stock from a very heavy feed obtained from a petroleum crude is disclosed. The bright stock produced by the present process has a reduced cloud point and better oxidation stability relative to bright stocks prepared by conventional methods. The process comprises the steps of providing a petroleum residuum-derived stream; separating the residuum-derived stream at a distillation cut point in the range of 1150° F. to 1300° F., into a heavy fraction and at least one light fraction; hydrocracking the at least one light fraction under conditions to reduce the concentration of sulfur and nitrogen to suitable levels for hydroisomerization dewaxing; and dewaxing at least a portion of the hydrocracked stream under hydroisomerization conditions to produce a lubricant bright stock.
