摘要： A process is provided for the conversion of a hydrocarbon feedstock using catalyst system comprising one or more zeolites. The zeolites have been identified to be capable of selectively catalyzing the hydroisomerization reactions of linear or slightly branched long-chain hydrocarbons. Also provided is a method for the systematic discovery of zeolite framework types that are suitable for such conversion processes, according to a set of criteria: large affinity towards linear alkanes, high adsorption selectivity of linear over branched alkanes, and low adsorption selectivity of linear alkanes of different molecular weights.

摘要： A process for separating ethanol from a mixture including ethanol and water comprises contacting the mixture with a sorbent or membrane including one or more zeolites having a high adsorption selectivity toward ethanol over water, wherein at least a fraction of the ethanol from the mixture is adsorbed by the sorbent or membrane and an unadsorbed portion of the mixture forms a raffinate having a lower concentration of ethanol than the mixture. The process further includes releasing adsorbed ethanol from the sorbent or membrane as a retentate or a permeant to produce an ethanol extract having a higher concentration of ethanol than the mixture.
