摘要： An atmospheric CO2 capture system includes a compartment housing a solid CO2 sorbent, an exchange fluid including a chemical component with selectivity towards CO2, and an electrochemical cell in fluid communication with the compartment, the system having a cycle including a first state of sorbing CO2 from incoming air onto the solid CO2 sorbent until a saturation point is reached; a second state of regenerating the sorbent by flooding the compartment with the exchange fluid to detach CO2 from the saturated sorbent and bind the detached CO2 to the chemical component; and a third state of regenerating the chemical component by detaching CO2 from the chemical component in the electrochemical cell and releasing the CO2 from the system.

摘要： Methods and systems for producing aromatics and light olefins from a mixed plastics stream are described. The method may include feeding a plastic feedstock to a dechlorination operation to melt the plastic feedstock to release HCl and generate a liquid plastic stream; feeding the liquid plastic stream to a pyrolysis reactor, the pyrolysis reactor to generate hydrocarbon vapors; feeding the hydrocarbon vapors to an acid gas removal reactor with a solid inorganic alkali salt disposed within the reaction vessel to remove residual HCl and sulfur-containing compounds from the hydrocarbon vapors to generate a plastic derived oil; and feeding the plastic derived oil to a fluid catalytic cracking reactor to generate a product stream comprising light olefins having a carbon number of C2-C4 and aromatics. The associated system for processing mixed plastics into aromatics and light olefins is also described.

摘要： An adsorption bed utilizing Metal Organic Framework canisters to process flue gasses exiting from power generation plants. High temperature flue gas from a power generation is cooled and enters MOF containers where CO2 is adsorbed. CO2 is then de-adsorbed with additional high temperature flue gas. CO2 is collected and removed from flue gas. Electricity is generated using the heat differential and collected to power the device. Electronic control system uses sensors and controls valves, pumps, cooling system and MOF gates.

摘要： The invention includes systems, methods, compositions, and processes for designing, manufacturing, and utilizing carbon dioxide-sequestering substrates that can fully or partially replace natural sand in coastal engineering applications. These engineered substrates can offset demand for scarce native sand resources, while also effecting the conversion of gaseous carbon dioxide to dissolved or solid-phase products thereby offsetting impacts of anthropogenic climate change.

摘要： Some embodiments of the disclosure correspond to, for example, a method for controlling a scrubber containing an adsorbent. The scrubber may be configured to cycle between scrubbing at least one pollutant/gas from a stream of gases with the pollutant/gas being adsorbed onto the adsorbent, and regenerating at least some of the adsorbent and thereby purging at least some of the one pollutant and/or first gas from the adsorbent via a regeneration gas flow. The method may include flowing a stream of gases through the scrubber, the scrubber including the adsorbent and adsorbing at least some of the one pollutant/gas from the stream of gases onto the adsorbent during an adsorption phase over a first time period. The method may also include purging at least a portion of the one pollutant/ gas from the adsorbent during a regeneration phase over a second time period with a regeneration gas flow, and cycling therebetween. Some other embodiments of the disclosure, for example, include an air treatment assembly which includes an adsorbent for adsorbing at least on pollutant/gas from a flow of air in one direction, and purging at least some of the adsorbed pollut -ant/gas from the adsorbent with a regeneration air flow to regenerate the adsorbent.

摘要： A method and apparatus for removing nitrogen oxides from gas streams, includes introducing a to-be treated gas stream into a gas-solid reaction column, and introducing ferric chloride solid particles into the gas-solid reaction tower at the same time. The nitrogen oxides in the gas streams undergo gas-solid chemical adsorption reaction with the ferric chloride solid particles to form solid products and are removed, and thereby purifying the gas.
