    • A polycyclic aromatic is contacted with an alkyl-substituted single ring aromatic, such as toluene, o-, m- or p-xylene or mesitylene, over a catalyst comprising a zeolite, such as zeolite beta, USY or ZSM-5 to alkylate the polycyclic aromatic. The polycyclic aromatic can be a fused polynuclear aromatic, e.g. phenanthrene, or an assembly of two or more cyclic systems, e.g. biphenyl. The polycyclic aromatic can also include carbocyclic systems such as fluorene and naphthalene or heterocyclic systems such as benzothiophene and dibenzothiophene. The polycyclic aromatic can be derived from a cycle oil, coker gas oil, extract of lubricant solvent refining or crude distillate fraction. The transalkylating agent can be derived from a reformate, pyrolysis gasoline or coker naphtha.

    • Petroleum waxes are converted to high viscosity index lubricants by a hydroisomerization process in which the wax feed is subjected to hydroisomerization over a low acidity molecular sieve isomerization catalyst (the molecular sieve being preferably a zeolite) which effects a preferential isomerization on the paraffin components in the feed to less waxy, high VI isoparaffins. The hydroisomerization is operated at high pressure, at least 1000 psig hydrogen partial pressure (reactor inlet) using a zeolite catalyst, preferably a noble metal containing zeolite beta catalyst which contains boron as a framework component of the zeolite to give a low alpha value, typically below 10. The hydroisomerization is carried out at with a 650° F.+ conversion in the range of 10 to 40 weight percent of the feed. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have VI values in excess of 125 and usually in the range of 130 to and are characterized by exceptional stability.
