    摘要: A method for producing a lube basestock from a waxy feed is disclosed in which a feed containing to 50 wt % or more of wax is hydrotreated and stripped to lower the nitrogen and sulfur content of the feed. The feed is then hydroisomerized under conditions to 370null C. hydrocatalytically dewaxed with a catalyst comprising a mixture of a catalytically active metal on a zeolite dewaxing catalyst and an amorphous catalyst, or alternatively is solvent dewaxed and then hydrocatalytically dewaxed with the just described catalyst.

    摘要: Alkylbenzene/polyol ester blends and alkylbenzene/polyalkylene glycol blends with a high proportion of alkylbenzene that offer a reduced cost alternative to polyol esters and polyalkylene glycol are disclosed. The alkylbenzene/polyol ester blends and alkylbenzene/polyalkylene glycol blends have sufficient HFC refrigerant solvency to operate satisfactorily. By mixing 60-80 wt % alkylbenzene with 20-40 wt % polyol ester or 20-40 wt % polyalkylene glycol, a product with beneficial properties from each component at a reduced cost is achieved.
