Abstract: Systems and methods for contacting a crude feed with one or more catalysts produces a total product that include a crude product are described. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The one or more catalysts may include one or more vanadium catalysts. Methods and compositions of the one or more vanadium catalysts are described. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed. In some embodiments, hydrogen is generated.

Abstract: Foaming of a lube oil comprising a base stock derived from wax isomeration and an additive package is effectively reduced to within specification limits of 50 ml/ml over a temperature range of from at least 24.degree. C. to 93.5.degree. C. by adding to the oil an effective amount of an antifoamant exhibiting a spreading coefficient of at least about 2 mN/m. This has been found to be particularly effective in reducing foaming of lube oils containing a mixture of a wax isomerate oil and a petroleum oil fraction. Antifoamants typically used with conventional lube oils containing one or more petroleum fraction base stocks, but which do not exhibit a spreading coefficient of at least 2 mN/m with the wax isomerate containing oil, have been found not to be effective in reducing the foaming of the oil.
