摘要： The present invention is a process for operating equilibrium controlled reactions in continuous mode wherein a feedstock is reacted in a plurality of reactors containing an admixture of a desired process catalyst and an adsorbent to form a product which is selectively adsorbed by the adsorbent and an admixture containing a product which is withdrawn from the reactor. A series of separation steps is used to desorb the product which is selectively adsorbed by the adsorbent and to prepare the reactor for a subsequent process cycle. The process utilizes a novel series of adsorption and desorption steps to collect the less selectively adsorbed product in substantially pure form under relatively constant flow rate at feedstock pressure.

摘要： A process for producing carbon monoxide (CO) by reforming methane and steam in the presence of a reforming catalyst to produce a reformate product enriched in CO, carbon dioxide (CO2) and hydrogen. CO2 in the enriched reformate is shifted to CO in an integrated sorption enhanced reaction (SER) cycle which employs a series of cyclic steps to facilitate reaction of CO2 and hydrogen at high conversion and to produce a CO-enriched product obtained at reactor feed pressure and at essentially constant flow rate. A series of adsorbent regeneration step including depressurization, purging and product pressurization are used to desorb water which is selectively adsorbed by the adsorbent during the shift reaction and to prepare the reactor for a subsequent process cycle.

摘要： A condensable component present at low concentration in a feed gas mixture containing the condensable component and a noncondensable component is recovered by selective adsorption from the feed gas mixture in an adsorption step, the resulting adsorbed condensable component is desorbed by a heated purge gas in a regeneration step to yield a purge gas effluent enriched in desorbed condensable component, and the purge gas effluent is cooled to condense and recover the condensable component as a liquid. An improvement comprises, during a time period of the regeneration step in which the concentration of the condensable component in the purge gas effluent reaches a maximum value, (a) dividing the purge gas effluent into a first and a second portion, (b) cooling the first portion of the purge gas effluent to a temperature sufficient to condense substantially all of the condensable component present therein and recovering the resulting condensate therefrom, and (c) cooling a second portion of the purge gas effluent and combining the resulting cooled gas stream with the feed gas mixture to yield a total feed mixture for the adsorption step.

摘要： A method for increasing product recovery or reducing the size of steam methane reformer and pressure swing adsorption systems utilized for hydrogen production. A significant portion of the hydrogen in the PSA depressurization and purge effluent gas, which is otherwise burned as fuel in the reformer, is recovered and recycled to the PSA system to provide additional high purity hydrogen product. This is accomplished by processing selected portions of the depressurization and purge effluent gas in adsorbent membrane separators to increase hydrogen content for recycle to the PSA system. Remaining portions of the depressurization and purge effluent gas which contain lower concentrations of hydrogen are utilized for fuel value in the reformer.

摘要： Recovery of hydrogen from hydrogen-containing gas mixtures by pressure swing adsorption is increased by utilizing an adsorbent membrane to concentrate hydrogen in the pressure swing adsorption reject gas and recycling the resulting hydrogen-enriched stream to the feed of the pressure swing adsorption system. Lower compression requirements are realized compared with the use of polymeric membranes for the same service because the hydrogen-enriched stream is recovered from the adsorbent membrane as nonpermeate at essentially the membrane feed pressure. Simultaneous permeation of carbon dioxide and methane occur in the adsorbent membrane, which can be operated at feed pressures as low as 5 psig when hydrogen is used as a sweep gas.

摘要： New methods are disclosed for decontaminating surfaces and enclosures that avoid problems such as salt deposits, corrosion and condensation that accompany the use of known methods. The methods involve the use of chlorine dioxide solutions prepared by passing dilute chlorine gas over solid granular sodium chlorite to produce chlorine dioxide gas which is then collected to form a solution with very low levels of impurities. The chlorine dioxide gas can be introduced into an enclosure and used to disinfect a portion of the contents of the enclosure.

摘要： Methods and apparatus relate to catalysts and preparation of the catalysts, which are defined by sulfides of a transition metal, such as one of molybdenum, tungsten, and vanadium. Precursors for the catalysts include a metal ion source compound, such as molybdenum trioxide, and a sulfide ion source compound, such as thioacetamide. Once the precursors are dissolved if solid and combined in a mixture, homogenous precipitation from the mixture forms the catalysts. Exemplary uses of the catalysts include packing for a methanation reactor that converts carbon monoxide and hydrogen into methane.
