    摘要: A process for the hydroisomerization of a predominantly C.sub.8 -C.sub.20 n-paraffinic feed to produce a high purity C.sub.8 -C.sub.20 paraffinic solvent composition having superior low temperature properties, and low viscosities. The feed is contacted, with hydrogen, over a dual functional catalyst to hydroisomerize and convert the feed to a product comprising a mixture of n-paraffins and isoparaffins, the isoparaffins component of which contains greater than 50 percent of mono-methyl species, with the molar ratio of isoparaffins:n-paraffins ranging from about 0.5:1 to 9:1.

    摘要: Discloses environmentally friendly, low temperature base oils and drilling fluids, or drilling mud compositions useful in the production of oil and gas. The drilling fluid is constituted of one or more of weighting agents, emulsifiers, wetting agents, viscosifiers, fluid loss control agents, proppants, and other particulates such as used in a gravel pack, emulsified with a paraffinic solvent composition which forms a continuous oil phase, or water-in-oil invert phase. The solvent composition is constituted of a mixture of C.sub.10- C.sub.24 n-paraffins and isoparaffins having an isoparaffin:n-paraffin molar ratio ranging from about 0.5:1 to about 9:1, the isoparaffins of the mixture contain greater than 30 percent, preferably from about 30 percent to about 50 percent, of mono-methyl species, and greater than 30 percent, preferably from about 30 percent to about 50 percent of multi-methyl branched species and isoparaffins which contain one or more branches of carbon number higher than methyl, based on the total weight of the isoparaffins in the mixture. The presence of the mono-methyl species is sufficient to provide the admirable environmentally friendly qualities, and the multi-methyl branched and isoparaffin species more highly branched than methyl provide low temperature properties.

    摘要: Discloses high purity solvent compositions constituted of n-paraffins and isoparaffins, with the isoparaffins containing predominantly methyl branches, and having an isoparaffin:n-paraffin ratio sufficient to provide superior low temperature properties and low viscosities. The solvent compositions are made by a process wherein a waxy, or long chain paraffinic feed, especially a Fischer-Tropsch wax, is reacted over a dual function catalyst to produce hydroisomerization and hydrocracking reactions at 700.degree. F.+ conversion levels ranging from about 20 to 90 wt.% to provide a C.sub.5 -1050.degree. F. crude fraction. The C.sub.5 -1050.degree. F. crude fraction is then topped via atmospheric distillation to produce a low boiling fraction with an upper end point boiling between about 650.degree. F. and 750.degree. F. The low boiling fraction is fractionated and a narrow boiling range solvent obtained therefrom; one which can be further divided into solvent grades of various boiling ranges.
