A process is described for converting at least one isomer of a dialkyl-substituted biphenyl compound, such as at least one 2,X' dialkylbiphenyl isomer (where X&#x2032; is 2&#x2032;, 3&#x2032; and/or 4&#x2032;), into at least one different isomer, 3,3&#x2032;, 3,4&#x2032; and/or 4,4&#x2032; dialkylbiphenyl isomer. The process comprises contacting a feed comprising the dialkyl-substituted biphenyl compound isomer with an acid catalyst under isomerization conditions.

Production and use of dialkylbiphenyl isomer mixtures

Provided are catalysts including: a zeolite component selected from zeolites having 10-member ring pores, zeolites having 12-member ring pores and a combination thereof, 0.1 to 5 weight % of a hydrogenation component selected from Pt, Pd, Ag, Ni, Co, Mo, W, Rh, Re, Ru, Ir and a mixture thereof, and a hydrothermally stable binder component selected from tantalum oxide, tungsten oxide, molybdenum oxide, vanadium oxide, magnesium oxide, calcium oxide, yttrium oxide, lanthanum oxide, cerium oxide, niobium oxide, tungstated zirconia, cobalt molybdenum oxide, cobalt molybdenum sulfide, nickel molybdenum oxide, nickel molybdenum sulfide, nickel tungsten oxide, nickel tungsten sulfide, cobalt tungsten oxide, cobalt tungsten sulfide, nickel molybdenum tungsten oxide and nickel molybdenum tungsten sulfide, cobalt molybdenum tungsten oxide and cobalt molybdenum tungsten sulfide, wherein the weight ratio of the zeolite to the hydrothermally stable binder is 85:15 to 25:75.

Dewaxing catalysts

Methods are provided for improving the yield of distillate products from hydroprocessing of gas oil feedstocks, such as vacuum gas oils. It has been unexpectedly found that stripping of gases or fractionation to separate out a distillate fraction during initial hydrotreatment of a feed can provide a substantial increase in distillate yield at a desired amount of feedstock conversion. The improvement in yield of distillate products can allow a desired level of conversion to be performed on a feedstock for generating lubricating base oil products while reducing or minimizing the amount of naphtha (or lower) boiling range products. Alternatively, the improvement in yield of distillate products can correspond to an improved yield during a single pass through a reaction system, so that distillate yield is increased even though a lubricant boiling range product is not generated.

Hydrocracking of gas oils with increased distillate yield

Sweet and sour lubricant feeds are block and continuous processed to produce lubricant basestocks. Total liquid product yields at a desired pour point are maintained for catalytic dewaxing of both sweet and sour conditions. The desired pour point is achieved for both the sweet and sour feeds by varying the catalytic dewaxing reaction temperature as a function of sulfur content entering the reactor.
