摘要:
The present invention pertains to a pervaporation membrane process for the separation of high octane fuel components from a gasoline feed stream comprising feeding a mixed phase vapor-liquid feed to a cyclone separation means to separate the liquid from the vapor, then sending the saturated vapor to the membrane, thereby extending the useful life of the membrane.

摘要:
The present invention relates to a polymeric aromatic selective membrane comprising an cross linked polyether imide membrane that comprise the reaction of a polyether amine with an dianhydride, and that may be utilized in a process for selectively separating aromatics from a hydrocarbon feedstream comprised of aromatic and aliphatic hydrocarbons and at least one alcohol, typically ethanol.
摘要:
A device for separating fuel components comprising a separating membrane for separating high-octane fuel components from un-separated fuel and a heat exchanger between first liquid passing through the heat exchanger and second liquid passing through the heat exchanger, is provided. The first liquid is un-separated fuel passing through the heat exchanger before being supplied to the separating membrane. The second liquid is low-octane fuel remaining when the high-octane fuel components are separated from the un-separated fuel, passing through the heat exchanger after changing to an almost liquid phase.
摘要:
A device for separating fuel components comprises a separating membrane for separating high-octane fuel components from un-separated fuel, a heater for heating the un-separated fuel and a pressure apparatus for pressurizing the un-separated fuel. In the device, un-separated fuel is heated by the heater and is pressurized by the pressure apparatus such that the state of the un-separated fuel is changed to a mixed gas phase and liquid phase state of a gas weight ratio from 50% to 95% before coming into contact with the separating membrane.
摘要:
A hydrocarbon conversion process for producing an aromatics product containing of benzene, toluene, xylenes, or mixtures thereof. The process is carried out by converting precursors of benzene, toluene, and xylenes that are contained in a hydrocarbon feed (C6+ non-aromatic cyclic hydrocarbons, A8+ single-ring aromatic hydrocarbons having at least one alkyl group containing two or more carbon atoms; and A9+ single-ring aromatic hydrocarbons having at least three methyl groups) to produce a product that contains an increased amount of benzene, toluene, xylenes, or combinations thereof compared to said hydrocarbon feed.
