摘要： A process for oligomerizing isobutene comprises contacting a feedstock comprising isobutene with a catalyst comprising a MCM-22 family molecular sieve under conditions effective to oligomerize the isobutene, wherein said conditions including a temperature from about 45° C. to less than 140° C. The isobutene may be a component of a hydrocarbon feedstock containing at least one additional C4 alkene. In certain aspects, isobutene oligomers are separated from a first effluent of the oligomerization to produce a second effluent comprising at least one n-butene. The second effluent can be contacted with an alkylation catalyst to produce sec-butylbenzene.

摘要： Heavy oil feeds are hydroprocessed in the presence of a solvent and in the presence of a catalyst with a median pore size of about 85 Å to about 120 Å under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

摘要： This invention is directed to a process for producing a hydroprocessed product. The invention is particularly advantageous in that substantially less hydrogen is absorbed during the process relative to conventional hydroprocessing methods. This benefit is achieved by using a particular solvent as a co-feed component. In particular, the solvent component contains at least one single ring aromatic compound and has a relatively low boiling point range compared to the heavy hydrocarbon oil component used as another co-feed component.
