Abstract: A method and system for producing nano-active powder materials. The method can be used with a reactor system comprising stages in which input particles flow under gravity progressively through stages of the reactor. A powder injector first stage in which ground input precursor powder is injected into the reactor. An externally heated preheater stage may be in the reactor, in which the precursor powder is heated to a temperature of calcination reaction. An externally heated calciner stage in the reactor, in which primary precursor volatile constituents can be rapidly removed calcination reactions as a high purity gas stream to produce the desired nano-active product. A post-processing reactor stage in which there is a change of the gas stream composition to produce the desired hot powder product by virtue of the nano-activity of the first powder material. A powder ejector stage in which the hot powder product is ejected from the reactor.

Abstract: The invention provides a powder-gas heat exchanger for exchanging heat between a powder stream and a gas stream in counter-current flow comprising a powder stream mass flow rate substantially equal to a gas stream mass flow rate in a vertical shaft heat exchanger. A hot gas stream may be adapted for use in heating a cool solids stream, or a cool gas stream may be adapted for use in cooling a hot solids stream.

Abstract: A method of manufacture of high-solids hydroxide slurries from caustic calcined carbonate powder is described, whereby the properties of the slurry are its low resistance to shear thinning to facilitate transport, a high stability for transport and storage, ease of reconstitution after long periods of storage, and, as required, a high concentration of chemically reactive species at the particle surface. The method achieves these specifications by mixing caustic calcined carbonate or hydroxide powder with water in an insulated reactor vessel, and agitating the slurry sufficiently such that the hydration reaction causes the water to spontaneously boil, such that the remaining hydration proceeds spontaneously under the fixed conditions of boiling through the water loss. The mixing process is preferably carried out by a shear pump. A viscosity modifier, such as acetic acid, is used to thin the slurry to enable the mixing system to maintain uniform mixing. The reaction is terminated when the boiling has spontaneously ceased and the temperature has spontaneously dropped to a set point though the reactor heat losses, where the processing time is sufficiently long that the slurry meets the desired specifications.

Abstract: A formulation for a coating for applications on maritime infrastructure or vessels to inhibit fouling and corrosion that comprises: (a) a nano-active material; and (b) a polymer binder; and (c) additives which include pigments, booster antifoulants, booster anticorrosion materials, solvents, polymerisation activators, viscosity modifiers and fillers, where the nano-active material, the binder and additives provide the coating with the desired most desirable properties of antifoul, anticorrosion, adhesion, and strength, required for the coating application.

Abstract: A process for processing an electroactive mesoporous material into a cathode, or an anode or a supercapacitor material using one or more of the steps of: (a) modifying the material to remove impurities or substitute materials in the powder by a hydrothermal process; (b) intercalating the material by injecting the material with the charge carrier ion using a hydrothermal process or supercritical CO2 fluid process where the solvent fluid contains a soluble material of the charge carrier ion; (c) sintering the intercalated material; (d) providing a layer of a conducting material within the material pores; (e) filling the pores and interparticle spaces with an electrolyte generally comprising the charge carrier ion and a solvent; and for solid state materials, (f) polymerizing the solvent to encapsulate the powders.

Abstract: A system for the calcination of powder materials comprising a plurality of vertical reactor tubes in which a falling powder is heated about a heating zone by radiation from the externally heated walls of the reactor tubes, in which the calcination process of the powder may be a reaction which liberates a gas, or induces a phase change; wherein the average velocity of the particles of falling powder during its transit through the reactor tubes is 1.0 m/s or less; the powder material flux for each tube is preferably in the range of 0.5-1 kg m-2 s-1, and wherein the length of the heating zone is in the range of 10 to 35 m.
