摘要: In some embodiments, the present disclosure pertains to methods of removing heteroatoms from a fluid by associating the fluid with one or more adsorbents, where the association results in the removal of the heteroatoms from the fluid. The association may occur by associating the fluid with a single adsorbent or a plurality of adsorbents in a sequential manner that maximizes heteroatom removal efficacy. The methods may be utilized to remove heteroatom-containing compounds from various fluids, such as fuels, hydrocarbons, alcohols, water, organic solvents, and combinations thereof. The one or more adsorbents may include, without limitation, activated carbon, zeolites, ion exchanged zeolites, ion impregnated zeolites, alumina, alumina nanowires, carbon-based supports, and combinations thereof. The methods of the present disclosure can be utilized to reduce heteroatoms in the fluid by more than about 50%, by more than about 80%, or by more than about 99%.

摘要: Organic sulfur compounds contained in refinery off gas streams having either high ort low concentrations of olefins are converted to hydrogen sulfides which can be then be removed using conventional amine treating systems. The process uses a catalytic reactor with or without a hydrotreater depending on the olefin concentration of the off gas stream. The catalytic reactor operates in a hydrogenation mode or an oxidation mode to convert a majority of organic sulfur compounds into hydrogen sulfides.

摘要: The invention relates to membrane gas separation, in particular to a method of fractionating mixtures of low molecular weight hydrocarbons based on the capillary condensation of the mixture components in the pores of microporous membranes having uniform porosity and a pore diameter of 5 to 250 nm, wherein, for capillary condensation, the temperature of the membrane and the pressure on the permeate side are kept below the temperature and the pressure of the feed mixture. The method provides significantly increasing membrane permeability with respect to condensable components, and also component separation factors, while also allowing to avoid deep cooling of the gas stream fed to a membrane module, and to carry out gas separation under insignificant cooling of the membrane on the permeate side (down to -50° C.). The invention provides for energy-efficient fractionation of hydrocarbon mixtures, including separation and drying of natural and associated petroleum gases.

摘要: Provided is a separation membrane that when used in membrane separation of a mixture of a linear hydrocarbon and a branched hydrocarbon and/or cyclic hydrocarbon of equivalent carbon number to the linear hydrocarbon, can efficiently separate the linear hydrocarbon and the branched hydrocarbon and/or cyclic hydrocarbon. The separation membrane includes a porous support and a porous separation layer disposed on the porous support and containing an MFI-type zeolite. In an X-ray diffraction pattern obtained through X-ray diffraction measurement of the porous separation layer, the intensities of diffraction peaks attributed to specific MFI-type zeolite crystal planes satisfy specific relationships.

摘要: We provide a method for removing contaminants from a gas, comprising: alternating input of the gas between two or more beds of adsorbent particles that comprise zeolite SSZ-36, zeolite SSZ-39, or zeolite SSZ-45; wherein the gas contacts one of the beds during an adsorption and a tail gas is simultaneously vented from another of the beds by desorption; wherein a contacting pressure is from about 345 kPa to about 6895 kPa and produces a product gas containing no greater than about 2 mol % carbon dioxide, at least about 10 wppm water, at least about 65 mol % of methane recovered from the feed gas, and at least about 25 mol % of ethane recovered from the feed gas; and wherein the tail gas is vented from the feed end of the beds. We also provide a method for removing a contaminant from a gas, wherein the gas contains hydrogen sulfide.
