Tunable, rapid uptake, aminopolymer aerogel sorbent for direct air capture of CO

A pair of bonded substrates having a first substrate of a first material, a second substrate of the first material, and an adhesive bonding the first substrate to the second substrate, wherein the adhesive has chemically linked compatibilizing particles compatible with the first and second substrates. A composition of matter has an adhesive having a chemically linked particle network forming a bond between a first substrate and a second substrate, wherein compatibilizing particles in the particle network are compatible with the first and second substrates. A method of joining two structures of identical materials includes preparing first and second structures to expose bare material, applying an adhesive to the bare material on the first and second structures, the adhesive containing compatibilizing particles compatible with the material and the preparing allows interaction between the material and the compatibilizing particles, and curing the adhesive.

Adhesive with substrate compatibilizing particles

A method for producing a homogenous molten composition and a fluid product is disclosed. For example, the method includes producing a first molten metal composition in an enclosed volume, contacting a hydrocarbon reactant with the first molten metal composition, decomposing the hydrocarbon reactant into at least one fluid product and carbon, forming a metal alloy from a mixture of the carbon and the first molten metal composition, and separating a homogenous second molten composition from the metal alloy.

Process and system for steel and hydrogen production using recycled ferrous scrap and natural gas

A porous polymer aerogel, wherein the aerogel has greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone. A method of fabrication of a porous polymer aerogel amine material, includes preparing a solution comprising at least a solvent, amine monomers having protected amino groups, one or more crosslinkers, one or more radical initiators, and a nitroxide mediator, removing oxygen from the solution, heating the solution to promote polymerization and to produce a polymerized material, performing solvent exchange with the polymerized material, causing a deprotection reaction in the polymerized material to remove groups protecting the amino groups, soaking and rinsing the material to remove excess reagents and any byproducts of the deprotection reaction, and drying the material to produce the amine sorbent. A system to separate CO2 from other gases, comprising a polymer porous aerogel sorbent having greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone.

A method of removing carbon dioxide from an atmosphere and generating hydrogen includes capturing carbon dioxide from the atmosphere in an alkaline capture solution, sending the alkaline capture solution to a series of electrolyzers in a CO-rich path, wherein each electrolyzer cell raises the acidity of the input CO-rich solution to produce an acidified CO-rich solution, removing carbon dioxide from the acidified CO-rich solution at a carbon dioxide removal unit operation to produce a CO-poor solution, sending the CO-poor solution to the series of electrolyzers in a return path, wherein each electrolyzer raises the alkalinity of the return CO-poor solution to produce a basified CO-poor solution, wherein a difference in pH between the CO-rich solution and the CO-poor solution within each electrolyzer is less than 3, and returning the basified CO-poor solution to the carbon dioxide capture unit operation.

A system has an alkaline capture stream as an input, an alkaline depleted stream as an output, a carbon dioxide removal unit operation having a return stream as an output, and a series of electrolyzers, each electrolyzer to receive a CO-rich input stream and produce an acidified output stream that is more acidic than the CO-rich input stream, and to receive a return stream and produce a basified output stream that is more alkaline than the input return stream. A method of removing carbon dioxide from an atmosphere and generating hydrogen includes capturing carbon dioxide from an atmosphere in an alkaline capture solution, sending the alkaline solution as a CO-rich input solution to a series of electrolyzers in a CO-rich path, removing carbon dioxide from the acidified CO-rich solution at a removal unit to produce a CO-poor solution, sending the CO-poor solution to the series of electrolyzers in a return path, and returning the return solution to the alkaline capture stream. An electrolyzer is also discussed.
