    • 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.

    • A process for preparing hydrocarbons in the lube base oil range, lube base oils and lube oil compositions from a fraction with an average molecular weight above a target molecular weight and a fraction with an average molecular weight below a target molecular weight via molecular averaging is described. The fractions can be obtained, for example, from Fischer-Tropsch reactions, and/or obtained from the distillation of crude oil. Molecular averaging converts the fractions to a product with a desired molecular weight, for use in preparing a lube oil composition. The product can optionally be isomerized to lower the pour point, and also can be blended with suitable additives for use as a lube oil composition.

    • A specific baffle arrangement within a catalytic reactor improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit. The catalytic reactor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel. An inlet riser conduit forming a primary reaction zone extends generally within the shell from the lower end of the vessel to a location near the top of the vessel. A shroud surrounds the upper end of the riser conduit and forms an annular outlet for downwardly discharging a mixtrue of hydrocarbon and catalyst. An annular catalyst disengaging riser baffle for deflecting the mixture from the outlet toward the wall of the vessel is arranged on the outside of the riser conduit below the annular outlet and above the stripping zone. Still further, an annular catalyst disengaging wall baffle is arranged on the inside of the shell for again deflecting the mixture, now mostly catalyst, generally downwardly and toward the stripping zone of the vessel. Preferably, the riser baffle and the wall baffle are arrnaged within the shell such that the baffles in concert with the annular discharge outlet form a partial cyclone separating zone between the baffles to thereby improve the separation of hydrocarbon vapors from the catalyst. This cyclone action promotes early disengagement of hydrocarbon vapor from the catalyst and reduces undesirable catalyst carryover in the vapor to conventional cyclones through which the hydrocarbon products are recovered. At the same time, undesirable secondary cracking reactions in the dilute phase are minimized by lowering the concentration of spent catalyst in the dilute phase.
