Abstract: Systems and methods are provided for performing selective catalytic reduction on engine exhaust using ethanol from the engine fuel as the reducing agent. Fuel from a fuel tank or other fuel source can be passed through a separation module to produce a fuel stream with a reduced ethanol content and an ethanol-enriched fraction. After combustion of fuel under lean conditions, the combustion exhaust can be exposed to a catalyst system in the presence of the ethanol-enriched fraction.

Abstract: A process and apparatus useful for continuously contacting an alkane feed at a temperature within a range from 300° C. to 600° C. and a pressure within the range from 50 psig to 500 psig with one or more reactive ceramic membrane to form an alkene with some remaining alkane and hydrogen, the hydrogen in physical isolation from the alkane and alkene, separating the alkene from the remaining alkane, and recycling the alkane to contact the reactive ceramic membrane.

Abstract: Disclosed are methods and apparatuses for separating a wax product from a hydrocarbon feedstream by a) conducting a hydrocarbon feedstream to a membrane separation zone; b) retrieving at least one retentate product stream from the first side of the membrane element; c) retrieving at least one permeate product stream having a wax phase and an oil phase from a second side of the membrane element, wherein a pour point of the wax phase of the permeate product stream is higher than a pour point of the oil phase of permeate product stream; and d) separating a wax product from the wax phase of the permeate product stream.

Abstract: Asymmetric membrane structures are provided that are suitable for hydrocarbon reverse osmosis of small hydrocarbons. Separation of para-xylene from ortho- and meta-xylene is an example of a separation that can be performed using hydrocarbon reverse osmosis. Hydrocarbon reverse osmosis separations can be incorporated into a para-xylene isomerization and recovery system in a variety of manners.
