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： 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.

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： The present invention relates to a process for capturing carbon dioxide from a gas stream. The gas stream is contacted with solid adsorbent particles in an adsorption zone. The adsorption zone has at least two beds of fluidized solid adsorbent particles, and the solid adsorbent particles are flowing downwards from bed to bed. The solid adsorbent particles comprise 15 to 75 weight % of organic amine compounds. The gas stream entering the adsorption zone has a dew point which is at least 5° C. below the forward flow temperature of the coolest cooling medium in the adsorption zone. Carbon dioxide enriched solid adsorbent particles are heated, and then regenerated. The desorption zone has at least two beds of fluidized solid adsorbent particles, and the stripping gas is steam. The regenerated particles are cooled and recycled to the adsorption zone.

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： The present disclosure relates to a process for capturing carbon-dioxide from a gas stream. In order to capture the carbon-dioxide, a support is provided and potassium carbonate (K2CO3) is impregnated thereon to form an adsorbent comprising potassium carbonate (K2CO3) impregnated support. The adsorbent is activated to form an activated adsorbent. The gas stream is passed through the adsorber to enable adsorption of the carbon-dioxide on the activated adsorbent to form a carbon-dioxide laden adsorbent. The carbon-dioxide laden adsorbent is transferred to a desorber for at least partially desorbing the carbon-dioxide from the carbon-dioxide laden adsorbent by passing a carbon-dioxide deficient stream through the desorber. The partially regenerated adsorbent is returned to the adsorber for adsorbing the carbon-dioxide from the carbon-dioxide. The process of the present disclosure reduces the overall energy demand by partially regenerating the adsorbent.

摘要： The present invention provides a method for dynamically controlling the circulation rate of solids in an interconnected fluidized bed. When an interconnected fluidized bed is operating, it is available to control the circulation rate of solids by adopting the steps of adjusting the height difference between the orifice on the weir and the bottom surface of the bed region, adjusting the cross-sectional area of the above orifice, or adjusting the height of the above weir. By using multiple ways, the circulation rate of solids can be improved substantially. In addition, the curve of circulation rate of solids can be converged to the maximum circulation rate of solids effectively.
