摘要:
There is provided a structurally stable monolith substrate, suitable to provide carbon dioxide capture structure for removing carbon dioxide from air, having two major opposed surfaces, and further having a plurality of longitudinal channels extending between and opening through the two major opposed surfaces of the structurally stable monolith substrate; and a macroporous coating, adhered to the interior wall surfaces of the longitudinal channels, comprising an adherent, coating formed of cohered, compact mesoporous particles each being formed of a material that is compatible with the material forming the underlying substrate structure so as to become adherent thereto when coated. The mesoporous particles are capable of supporting in their mesopores a sorbent for CO2 There is also provided a method for forming the monolith and a system for utilizing the monolith as part of a CO2 capture structure, within the system, to remove CO2 from the atmosphere.
摘要:
A method for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO2. The CO2 is removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure CO2 and to regenerate the sorbent for repeated use. Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently. The above method provides purified carbon dioxide for further use in agriculture and chemical processes, or for permanent sequestration.

摘要:
A system for removing carbon dioxide from a carbon dioxide laden gas mixture, the system comprising two groups of carbon dioxide removal structures, each removal structure within each group comprising a porous solid mass substrate supported on the structure; and a sorbent that is capable of adsorbing or binding to carbon dioxide, to remove carbon dioxide from a gas mixture, the sorbent being supported upon the surfaces of the porous mass substrate solid; an endless loop support for each of the groups of the removal structures, the endless loop support being so arranged as to move the support structures of each group along a closed curve while being exposed to a stream of the gas mixture; and a sealable regeneration box at one location along each of the endless loop supports, in which, when a porous solid mass substrate is sealed in place therein, carbon dioxide adsorbed upon the sorbent is stripped from the sorbent and the sorbent regenerated; each removal structural supporting a porous substrate in a position to be exposed to a flow of carbon dioxide laden gas mixture so as to allow for the removal of CO2 from the gas mixture; the number of removal structures to the number of regeneration boxes being directly determined by the ratio of the time to adsorb CO2, from a base level to desired level on the sorbent, to the time to strip the CO2 from the desired level back to the base level.

摘要:
A system and method of reducing the net carbon dioxide footprint of an industrial process that generates power from the combustion of hydrocarbon fuels in which ambient air is admixed with up to 50% by volume of an effluent gas from the power generator of the industrial process, in order to substantially increase the CO2 concentration in the air prior to treatment. The treatment comprises adsorbing CO2 from the admixed ambient air utilizing a cooled, porous substrate-supported amine adsorbent, wherein the porous substrate initially contacts the mixed ambient air containing condensed water in its pores, which act as an intrinsic coolant with respect to the exothermic heat generated by the adsorption process. In addition, prior to regenerating the supported adsorbent, air pressure is substantially reduced in the sealed regeneration chamber and the low pressure chamber is placed in fluid connection with a higher pressure regeneration chamber containing steam and carbon dioxide, to preheat the sorbent to be regenerated and to quickly cool the regenerated sorbent prior to use for further CO2 adsorption.
