    摘要: Dewaxed lube base stock oil which forms a wax haze on storage at a temperature above its cloud point is treated by contacting the oil and hydrogen with a zeolite catalyst such as ZSM-5 to eliminate the wax-haze formation. The method may be used to reclaim wax-contaminated lube base stock oils and other wax-contaminated hydrocarbon oils.

    摘要: Hydrocracked, low pour lubricating oils of good stability are manufactured by passing a suitable hydrocarbon feed and hydrogen sequentially through a hydrocracking zone, a catalytic dewaxing zone, and a hydrotreating zone, all at high pressure and in that order, with purification of the hydrogen gas prior to passage to the dewaxing zone. By maintaining all zones at high pressure, the efficiency of the process is augmented.

    摘要: Hydrocracked, low pour lubricating oils of good stability are manufactured by passing a suitable hydrocarbon feed sequentially through a hydrocracking zone, a catalytic dewaxing zone, and a hydrotreating zone, all at high pressure and in that order, and with separation of hydrocrackate from recycle hydrogen prior to dewaxing. Only clean makeup hydrogen is fed to the dewaxer, passed through the hydrotreater, and then on to the hydrocracker, thereby providing an exceptionally efficient process.
