A process for deoxygenating a pyrolysis oil stream comprises purposely limiting complete deoxygenation of the pyrolysis oil stream having a high oxygenate concentration to provide a hydrotreated pyrolysis oil stream that is sufficiently reduced in oxygenate content to mix with oil. By not fully deoxygenating the pyrolysis oil stream, the deoxygenation reaction can be run with little risk of undesirable polymerization reactions plugging the reactor.

The present invention provided a high temperature resistant epoxy resins for producing hollow fiber membrane modules for high temperature gas separation applications such as for natural gas upgrading and hydrogen purifications. This invention also relates to a hollow fiber membrane module comprising a bundle of multiple high performance hollow fiber membranes and a tube sheet formed by a high temperature resistant cured epoxy resin that is used to fix and bound said bundle of multiple high performance hollow fiber membranes. The invention also provides a process for separating at least one gas from a mixture of gases using the hollow fiber membrane modules comprising a bundle of multiple high performance hollow fiber membranes and a tube sheet formed by a high temperature resistant cured epoxy resin that is used to fix and bound said bundle of multiple high performance hollow fiber membranes.

One exemplary embodiment is a membrane separation element. The membrane separation element can include a membrane and a feed spacer positioned adjacent to the membrane. The feed spacer may include a first layer, a second layer, and a third layer. Usually, a plurality of fibers of the second layer only touches a plurality of fibers of the first and third layers.

One exemplary embodiment can be a process for extracting sulfur compounds in a hydrocarbon stream. The process can include feeding a hydrocarbon stream containing sulfur compounds to a prewash zone containing an alkali, withdrawing a prewashed hydrocarbon stream from the prewash zone, and feeding the prewashed hydrocarbon stream to a mass transfer zone for extracting one or more thiol compounds from the prewashed hydrocarbon stream. Often, the mass transfer zone includes a hollow fiber membrane contactor.

The present invention involves a type of nanoporous macrocycle-containing cross-linked polymeric membrane, a method of making the membrane, and the use of such a novel membrane system for natural gas liquids (NGL) recovery, fuel gas conditioning, natural gas pre-treatment, sulfur removal from fluidized catalytic cracking (FCC) and other naphtha streams, as well as aromatic separations such as aromatic/paraffin separation and xylene separation. The nanoporous macrocycle-containing cross-linked polymeric membrane is prepared from a diisocyanate-terminated polyether or a diisocyanate-terminated polyester, that is crosslinked with a nanoporous macrocycle comprising hydroxyl functional groups such as &#x3b1;-, &#x3b2;-, and &#x3b3;-cyclodextrins.

The present invention discloses a new type of polyimide membrane with high permeances and high selectivities for gas separations and particularly for CO/CHand H/CHseparations. The polyimide membranes have COpermeability of 50 Barrers or higher and single-gas selectivity for CO/CHof 15 or higher at 50&#xb0; C. under 791 kPa for CO/CHseparation. The polyimide membranes have UV cross-linkable functional groups and can be used for the preparation of UV cross-linked polyimide membranes having COpermeability of 20 Barrers or higher and single-gas selectivity for CO/CHof 35 or higher at 50&#xb0; C. under 791 kPa for CO/CHseparation.

The present invention discloses a new type of high selectivity UV-cross-linked tetrazole group functionalized polymer nanosieve (TZPIM) membranes, their preparation, as well as their use for gas and liquid separations. The UV-cross-linked TZPIM membrane showed more than 50% improvement in CO/CHselectivity and more than 30% improvement in CO/Nselectivity compared to the uncross-linked TZPIM membrane for CO/CHand CO/Nseparations, respectively.
