Abstract: Systems and methods of direct air capture are described. Systems include a plurality of moving adsorber panels in a linear direction (or circular configuration) and one or more fans configured to move air across the adsorber panels; such adsorber panels may be oriented vertically or horizontally, relative to the ground. Systems may include an independent regeneration box that comprises a system of headers, ducts and valves configured to deliver and remove a plurality of gases to the regeneration box. The regeneration box contains multiple chambers such that steps such as oxygen removal and panel cooling may be performed independently from and simultaneously to thermal preheating and desorption of the CO2 on the panels. The desorption panels may be configured to achieve counter-current flow to the hot gases used for thermal preheating and desorption. A multi-stage heat pump may facilitate reuse of waste heat and decarbonization of the process heating requirements.

Abstract: The present disclosure relates to a mixed matrix carbon molecular sieve (CMS) membrane, a preparation method of the mixed matrix CMS membrane, and use of the mixed matrix CMS membrane in C2H4/C2H6 separation, and belongs to the technical field of membrane separation. The present disclosure solves the problem that the CMS materials in the prior art exhibit low selectivity and low flux during an ethylene/ethane separation process. In this patent, C3N4 is used as a filling particle to prepare a mixed matrix membrane (MMM), and the MMM is pyrolyzed to prepare a CMS membrane. The C3N4/6FDA-DAM MMM has prominent C2 separation performance.

Abstract: An oil skimming device for the removal of oil located at the surface of a body of water includes a float, at least one skimming surface, a sorbent material, at least one scraper, and a motor. The float is arranged such that the device rests on the surface of the body of water from which the oil is to be removed. The at least one skimming surface is rotatable about an axis such that when the device is floating in the water a portion of the ridged skimming surface is above and a portion of the skimming surface is below the water surface. The sorbent material is removably attached to and substantially covers the skimming surface. The sorbent material is configured to rotate with the skimming surface and to sorb oil as the skimming surface is rotated.
