摘要： A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.

摘要： Herein disclosed is a method of producing dimethyl ether (DME) comprising introducing one or more feed streams comprising methane and carbon dioxide into a reformer to generate synthesis gas; and converting synthesis gas to DME in one step. In some cases, the reformer comprises a Ni catalyst. In some cases, the reformer is a pressurized fluidized bed dry reforming reactor. In some cases, the reformer comprises a hydrogen membrane. The hydrogen membrane removes hydrogen contained in the synthesis gas and shifts reforming reactions toward completion.

摘要： The invention relates to a method for producing hydrocarbon products which comprises preparing a hydrocarbon stream (C4) which predominantly comprises branched and unbranched hydrocarbons each having four carbon atoms. A first and a second partial stream (i-C4, n-C4) are obtained from this stream (C4), the first partial stream (i-C4) predominantly comprising branched hydrocarbons with four carbon atoms and the second partial stream (n-C4) predominantly comprising unbranched hydrocarbons with four carbon atoms. The method further comprises the steam cracking of at least part of the first partial stream (i-C4) at a first, higher cracking severity and at least part of the second partial stream (n-C4), at a second, lower, cracking severity.

摘要： Disclosed is a method that reforms flare gas or other raw natural gas source, using air without steam, to directly produce dimethyl ether (DME), a direct diesel substitute. The method first reforms an air-natural gas mixture at ambient atmospheric pressures, and then compresses the resulting CO-hydrogen-nitrogen gas mixture to 100-2,000 psi, and feeds it through a combined reactor which reacts the gas mixture directly into DME. The nitrogen is returned to the atmosphere. DME is an excellent diesel fuel, and can be used to displace significantly costlier and dirtier petroleum-based diesel fuel, while solving a critical problem with flaring or other wasted natural gas. For example, the roughly 120 billion cubic feet per year that was flared in North Dakota in 2014 could be converted into over 3 million tons of DME using the disclosed method.

摘要： A process separates pure components from a product mixture produced by a one-step dimethyl ether synthesis reactor. The product mixture is scrubbed with pure dimethyl ether followed by scrubbing with aqueous methanol solvent in two absorption columns to reduce CO2 level and to minimize methanol and dimethyl ether loss with the recovered unconverted synthetic gas. The pure water or aqueous methanol is mixed with the vapor stream of CO2 separation distillation. Dimethyl ether, methanol and water mixture are separated. A scheme for separation of methanol and water mixture minimizes the size, energy and cost of separation. The process can be cost-effective, energy-efficient, environment-friendly and readily-miniaturized.

摘要： A unique design for a mobile system that reforms flare gas or natural gas, using air without steam, to directly produce dimethyl ether (DME), a diesel substitute, is disclosed. The system first reforms the air-methane mixture at ambient atmospheric pressures, and then compresses the resulting CO-hydrogen-nitrogen gas mixture to up to 600 psi, and feeds it through a combined reactor which reacts the gas mixture directly into dimethyl ether. The nitrogen is returned by the system back to the atmosphere. DME is an excellent diesel fuel, and can be used to displace significantly costlier and dirtier petroleum-based diesel fuel, while solving a critical problem with flaring. For example, the over 120 billion cubic feet per year that is currently flared in North Dakota could be converted into over 3 million tons of DME.

摘要： A fully automated flow assisted-solid-phase microextraction (FA-SPME) is developed for the determination of chloroethers in aqueous samples. A CTC CombiPAL autosampler coupled with gas chromatography-mass spectrometry (GC-MS) is used to automate the extraction process. In this method, the SPME fiber is exposed to a sample in direct immersion. After exposure, the fiber is desorbed at the injection port of GC-MS.
