摘要： Processes for the direct alkylation of ethylene with isobutane or isopentane using a highly active ionic liquid alkylation catalyst are described. Ethylene is sent to a high-temperature alkylation reactor loop, and C3, C4, and C5 olefins are routed to a low temperature alkylation reactor loop. In each reactor, the olefins are contacted with an excess of isobutane or isopentane in the presence of a highly active ionic liquid catalyst. Portions of the reactor effluent streams are fed to a common downstream catalyst separation and product fractionation sections. The remainder of the reactor effluent is recycled back to the respective alkylation reactor.

摘要： A method of alkylating a hydrocarbon stream including: providing a feed stream that includes hydrocarbons and ionic liquid catalyst; passing the feed stream through a low efficiency mixer to create a mixed stream, whereby the low efficiency mixer creates droplets within the feed stream that are primarily within a predetermined size range; passing the mixed stream and an olefin stream into a reactor; performing an alkylation reaction within the reactor, thereby forming a reacted stream; and separating the reacted stream into a settled ionic liquid catalyst stream and a hydrocarbon stream through the use of at least one hydrocyclone.

摘要： A hydrocarbon conversion process is described. The process involves contacting a hydrocarbon feed with a lactamium based ionic liquid catalyst in a reaction zone under reaction conditions to form a mixture comprising reaction products, and the lactamium based ionic liquid catalyst. Typical hydrocarbon conversion processes include alkylation, oligomerization, isomerization, disproportionation, and reverse disproportionation.

摘要： A process for producing dimethylhexanes (DMH) is provided. The DMH can be used to produce p-xylene. The process involves the alkylation of isobutane and 1-butene using an ionic liquid to produce naphtha that is rich in DMH. The DMH is then converted in high selectivity to xylene, including p-xylene, by dehydrocyclization.
