    摘要: Lubricant oils of low pour point and improved oxidation stability are produced by catalytically dewaxing a lube feedstock over a zeolite dewaxing catalyst such as ZSM-5 in the hydrogen or decationized form. The use of these catalysts enables products of excellent oxidative stability to be obtained and reduces the catalyst aging rate in the first and subsequent dewaxing cycles to values below 5° F./day. The duration of the dewaxing cycles may be extended, particularly in the second and subsequent cycles after hydrogen reactivation.

    摘要: A process for making a lubricant oil of low pour point which comprises a) catalytically dewaxing a lube boiling range feedstock in the presence of hydrogen over a dewaxing catalyst comprising an intermediate pore size zeolite in the hydrogen or decationized form during a dewaxing cycle in which the temperature is progressively increased to maintain a substantially constant product pour point to produce a lubricant oil product of improved oxidation stability. The feedstock is sequenced during a dewaxing cycle from a heavy feed to a lighter feed in order to avoid contacting the lighter feed with the catalyst in its most active conditions.

    摘要: When different trialkyl methanes containing 25 through 36 carbon atoms are mixed the mixture exhibits surprisingly superior lubricant properties including low viscosity, high VI, low volatility, very low pour point and a dynamic viscosity at low temperatures that is less than those of PAO lubricants. Statistically predictable mixture compositions of mixed trialkyl methanes are prepared by reaction of mixtures of n-alkyl organometallic compounds with mixed aliphatic esters or equivalent compounds.
