摘要： A system for hydrocarbon decomposition comprising a reactor volume, a mechanism to distribute the liquid catalyst as a liquid mist, a distributor to distribute a hydrocarbon reactant, a heat source, a separator to separate the solid product from the liquid catalyst, a re-circulation path and mechanism to re-circulate the liquid catalyst, and an outlet for at least one gaseous product. A system to distribute a liquid to an enclosed volume as a mist has a plurality of orifices designed to break the liquid into a mist. A method to decompose a hydrocarbon reactant includes generating a mist of a liquid catalyst, heating the reactor volume, introducing a hydrocarbon reactant into the reactor volume to produce a solid product and a gaseous product, separating the solid product from the liquid catalyst, removing the solid and gaseous products from the reactor volume, and recirculating the liquid catalyst to the reactor volume.

摘要： An acrylic adhesive composition includes a first part including an aminoborane initiator and acrylate or/and methacrylate monomers, and a second part including inert microcapsules of a cure activator and acrylate monomers, wherein the microcapsules are breakable, such that when broken, the first part reacts with the second part and the acrylic adhesive begins to cure. A two-part structural adhesive includes a suspension component containing an aminoborane initiator, and microcapsules containing an encapsulated component, wherein the microcapsules are dispersed in the suspension component. A method of activating an aminoborane initiator suspension to form a structural adhesive includes adding microcapsules containing an encapsulated component, to the aminoborane initiator suspension at a predetermined ratio, and breaking the microcapsules to activate curing.

摘要： A process for decomposing a hydrocarbon-containing composition includes feeding the hydrocarbon-containing composition to a reactor containing a catalytically active molten metal or a catalytically active molten metal alloy, wherein the metal or alloy catalyzes a decomposition reaction of the hydrocarbon-containing composition into a hydrogen-rich gas phase and a solid carbon phase. The solid carbon phase is insoluble in the metal or alloy. The process may be a continuous process.

摘要： A composition of matter has cement particles and resin structures having: a first functional group bonded directly to a surface of each cement particle; and a second functional group that bonds to calcium silicate hydrate upon hydration, wherein the second functional group is bondable with second functional groups of others of the cement particles to form a polymer network; and a backbone that connects the first functional group with the second functional group. A method of forming cement particles includes mixing cement particles with reactive molecules, the reactive molecules having a first functional group bonded directly to a surface of each cement particle, a second functional group that is bondable to calcium silicate hydrate upon hydration, wherein the second functional group is bondable with second function groups of others of the cement particles to form a polymer network, and a backbone that connects the first functional group with the second functional group. A composition of matter has cement particles, and a cured resin structure resulting from a reaction between two or more reactive molecules having functional groups that react with each other onto the surfaces of the cement particle, wherein one of the reactive molecules is used in less than a stoichiometric amount, leaving unreacted functional groups, and wherein the unreacted functional groups are bondable to calcium silicate hydrate upon hydration.
