Abstract:
The present invention is directed to a membrane for ethanol and aromatics separation that is stable in an alcohol containing environment, The membrane is a polyether epoxy resin having an aliphatic substituted epoxide. The invention also teaches a method to control the flux and selectivity of the membrane.
Abstract:
This invention relates to a process for the selective conversion of vacuum gas oil. The vacuum gas oil is treated in a two step process. The first is thermal conversion and the second is catalytic cracking of the products of thermal conversion. The product slate can be varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step. The combined products from thermal and catalytic cracking are separated in a divided wall fractionator.
Abstract:
The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt%, based on the hydrocarbon feed (8). The hydrocarbon feed (18) is treated in a two-step process. The first is thermal conversion (12) and the second is catalytic cracking (26) of the products of the thermal conversion (12). The present invention results in a process for increasing the distillate production (16) from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal (12) and catalytic cracking (26) steps as well as by changing the catalyst in the cracking step (26).
Abstract:
Heavy oil feeds are hydroprocessed in the presence of a solvent under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessmg. 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 hydroprocessmg catalyst.
Abstract:
The present invention is directed to a membrane for aromatics separation that is stable in an alcohol containing environment. The polymeric membrane is a epoxy amine based membrane.
Abstract:
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.
