ABSTRACT:
Waxes, for example waxes obtained from dewaxing hydrocarbon oils, called slack waxes, and synthetic waxes such as those obtained by Fischer-Tropsch processes, are isomerized into oils boiling in the lube oil boiling range, e.g., 370.degree. C.+, by contacting the wax under isomerization conditions and in the presence of hydrogen with an isomerization catalyst comprising a noble Group VIII metal on a small particle size refractory metal oxide support having a low total fluoride content catalyst wherein the total fluoride content is in the range of 0.1 to up to but less than 2 wt % fluoride and the support has a particle diameter of less than 1/16 inch. The small particle size refractory metal oxide support is preferably alumina or material containing alumina, preferably predominantly (i.e., >50%) alumina, more preferably an alumina such as gamma or eta. The most preferred alumina is 1/20 inch alumina trilobes. Noble metal content ranges from 0.1 to 2.0 wt %.
