    摘要: A process for making a lube base stock wherein an olefinic feedstock is separated into a light olefin fraction and a medium olefin fraction. The light olefin fraction is contacted with a first oligomerization catalyst in a first oligomerization zone to produce a first product. Both the medium olefin fraction and the first product are contacted with a second oligomerization catalyst in a second oligomerization zone to produce a second product. The second product is separated into a light byproduct fraction and a heavy product fraction that includes hydrocarbons in the lube base stock range.

    摘要: A process for making a lube base stock wherein a highly paraffinic feedstock (with boiling points within the range of from 258° to 1100° F.) is dehydrogenated to produce an olefinic feedstock, which is oligomerized to produce an oligomerized product, which is separated into a lighter fraction and a heavier fraction. That heavier fraction has a flash point within the lube base oil range.

    摘要: Methods and compositions for stabilizing the activity of catalytic compositions during catalytic processes, such as alkylation. A catalytic composition comprising a partially deactivated ionic liquid catalyst may be regenerated by reaction with a metal to form reactivated catalyst and an inorganic catalyst precursor; and the catalytic composition may be amended in-process by addition of an organic catalyst precursor for reaction with the inorganic catalyst precursor to form fresh ionic liquid catalyst. The organic catalyst precursor may be protected from water, e.g., during handling, by hydrophobic material(s).
