摘要： A process for removing hydrogen sulfide (H2S) from a H2S-containing gas composition includes charging a liquid to a reactor under continuous agitation and dispersing particles of a cobalt-based zeolitic imidazolate framework-67 (ZIF-67) in the liquid to form a ZIF-67 mixture. The method further includes introducing the H2S-containing gas composition to the reactor containing the ZIF-67 mixture under continuous agitation and passing the H2S-containing gas composition through the ZIF-67 mixture. In addition, the method includes adsorbing the H2S from the H2S-containing gas composition onto the ZIF-67 to remove the H2S from the H2S-containing gas composition and form a purified gas composition.

摘要： Disclosed herein is a gas capture system comprising: a first reactor system arranged so that, in the first reactor system, at least some gas in a gas stream that is received by the gas capture system is captured by a sorbent that is arranged to flow through the first reactor system; a second reactor system arranged to regenerate the sorbent so that the sorbent releases at least some of the gas captured in the first reactor system, wherein the sorbent is arranged to flow through the second reactor system and the second reactor system is arranged to output a flow of the released gas; a first sorbent transfer system arranged between a sorbent outlet of the first reactor system and a sorbent inlet of the second reactor system, wherein the first sorbent transfer system comprises a lock hopper; and a second sorbent transfer system arranged between a sorbent outlet of the second reactor system and a sorbent inlet of the first reactor system, wherein the second sorbent transfer system comprises a lock hopper; wherein: the sorbent is a solid; the second reactor system comprises a pump arranged so that the second reactor system may have a lower operational pressure when regenerating sorbent than the operational pressure of the first reactor system during gas capture by the sorbent; and the first reactor system, first sorbent transfer system, second reactor system and second sorbent transfer system are all arranged so that they provide a sorbent flow path that recirculates the sorbent between the first reactor system and the second reactor system.

摘要： Provided is a wet desulfurization process using a suspension bed. The process comprises mixing desulfurization slurry with a hydrogen sulfide containing gas to obtain a first mixture, and passing the first mixture into a suspension bed reactor from bottom to top, with controlling the first mixture to have a dwell time of 5-60 minutes in the reactor to allow they contact and react sufficiently with each other; and subjecting a second mixture obtained from the reaction to gas liquid separation to produce a purified gas. The process of the present invention may reduce the hydrogen sulfide content in the hydrogen sulfide containing gas from 2.4-140 g/Nm3 to 50 ppm or less, so that the desulfurization efficiency is 98% or more. The process of the present invention is simple and reasonable, with high desulfurization and regeneration efficiency, simple equipment, little occupation of land and low investment, which is very suitable for industrial promotion.

摘要： A process and a device for treating a flow of furnace gas with a pressure of more than 1 bar flowing through a channel. A powder agent, such as a powder comprising alkali reagents, such as lime, and/or absorbents, such as activated coal, is injected under an overpressure into the furnace gas flow via an injector which is positioned centrally within the channel. The powder agent may be fluidized. The pressure for injecting the powder may be adjusted by controlling the volume of fluidization gas vented via a venting outlet.

摘要： A method for producing an aroma composition from roasted coffee beans, including grinding roasted coffee beans to give a crude ground powder of roasted coffee beans that contains a fine powder and thin flakes, removing the fine powder and thin flakes from a gas that contains aroma compounds emitted from the roasted coffee beans in grinding the roasted coffee beans and the fine powder and thin flakes, introducing the gas from which the fine powder and thin flakes have been removed into an adsorbent to thereby make the aroma compounds adsorbed by the adsorbent, and collecting the aroma compounds from the adsorbent to prepare an aroma composition containing the aroma compounds. The adsorbent is held in an adsorbent holder in an aroma compound adsorbing device, and the adsorbent holder has a mesh lid at both ends thereof in the gas flowing direction therethrough.

摘要： A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

摘要： An emissions control system including a fluidized bed apparatus containing a reactive sorbent material is disclosed for gaseous and non-gaseous contaminated emissions. The reactive sorbent material may be CZTS, CZTS-Alloy, or a carbon-based sorbent material. The fluidized bed apparatus is configured with one or more closed loop sorbent recycling subsystems. The sorbent recycling subsystems include the capability to separate sorbents from each other, separate contaminates from sorbents for disposal and/or recycling, clean and/or rejuvenate sorbents for return to the fluidized bed apparatus, dispose of spent and exhausted sorbents, and replace the spent and exhausted sorbents with new sorbent to maintain consistent sorbent function in the fluidized bed apparatus. Monitoring sensors provide information useful in a method for establishing and maintaining consistent process parameter controls.
