Abstract: A process for producing a cathode or anode material adapted for use in the manufacture of fast rechargeable ion batteries. The process may include the steps of Selecting an precursor material that, upon heating in a gas stream, releases volatile compounds to create porous materials to generate a material compound suitable for an electrode in an ion battery. Grinding the precursor material to produce a powder of particles with a first predetermined particle size distribution to form a precursor powder. Calcining the precursor powder in a flash calciner reactor segment with a first process gas at a first temperature to produce a porous particle material suitable for an electrode in an ion battery, and having the pore properties, surface area and nanoscale structures for applications in such batteries. Processing the hot precursor powder in a second calciner reactor segment with a second process gas to complete the calcination reaction, to anneal the material to optimise the particle strength, and to modify the oxidation state of the product for maximising the charge density when the particle is activated in a battery cell to form a second precursor powder. Quenching the second precursor powder. Activating the particles of the second precursor powder in an electrolytic cell by the initial charging steps to intercalate electrolyte ions in the particles.

Abstract: A process and apparatus for manufacture of biocide products are described. The biocide properties arise from the caustic calcined powder, from carbonates such as such as magnesite and dolomite, and from hydroxides such as brucite. The method of manufacture is based on the production of high surface area oxide particles using an indirectly heated counterflow reactors for specifically calcining the carbonates and the hydroxides without significant sintering. The biocide products may be a powder or a hydrated slurry. A hydrated slurry is preferred for agricultural applications as a spray. For aquaculture applications, the products have a preferred particle size distribution to impact the aquatic and benthic ecosystems, and a Ca/Mg ratio that promotes the growth of the cultivates species when applied as a powder or a slurry. For applications such as a marine paint, the powder product or the slurry product is mixed with various agents to form a setting coating, and is applied to the infrastructure that is otherwise subject to biofilm growth.

Abstract: A process for producing a highly calcined and uniformly calcined product from a feedstock. The process comprising the steps of grinding the feedstock to powder, preheating the powder, and calcining the powder in a reactor plant that comprises a number of reactor segments in which a flash calciner is used in each progressive reactor segment to incrementally react the powder by raising the temperature in each segment. The last segment may be a high-temperature reactor that has a controlled residence time and temperature that may allow controlled finishing of the calcination process to achieve a desired degree of calcination and sintering of the product; and cooling of the product.

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 of a pathogen inhibitor or probiotic as a slurry concentrate of a hydrated metal oxide for applications in agriculture, aquaculture, and as an anti antibiotic in which the bioactivity, when applied by dilution, is controlled by a precursor of Reactive Oxygen Species, and the release rate is controlled by the particle size. The invention may include a means whereby the precursor concentration may be controlled to meet the requirements of the ecosystem, from the maintenance of an aerobic system, to killing pathogenic, anaerobic microbes, or producing sterile ecosystems. In addition, the metal oxide may be selected to provide essential nutrients for growth of the agricultural or aquacultural products.
