Abstract: A method of the invention for treatment of particulate material for metal recovery includes heating a furnace to a first temperature, feeding a particulate material into the furnace, and before or after heating of the raw material, feeding a reducing gas flow through the furnace. The particulate material is heated in the furnace for volatilizing one or more metals contained in the ash into the gas flow, and the volatilized particles are recovered in one or more collection units. A system for treatment of particulate material for metal recovery includes a heated furnace for receiving flows of reduction gas and particulate material, a collection unit for volatilized particles, and a collection unit for non-volatilized material.

Abstract: Provided is a method for forming catalytic nanocoating on a metal surface. The method comprises pretreating the metal surface by means of heat treatment at 500-800° C., forming a metaloxide support, and depositing catalytic nanosized metal and/or metaloxide particles on the metaloxide support and coating the metal surface with catalytic nanosized metal and/or metaloxide particles. Further, the invention relates to a catalyst and a use.

Abstract: A method and apparatus for multicomponent surface modified aerosol particle production suitable for, for instance, therapeutic, cosmetic or diagnostic use in which an aerosol containing an active agent is introduced in an aerosol reactor together with a surface agent or surface agent source and/or precursor and wherein the surface agent and/or surface agent precursor is volatilizable. The surface agent vapor saturation ratio is elevated so to cause it to nucleate from the gas phase. Reactor conditions are maintaining such that the active agent remains in the condensed phase and provides a surface for the surface agent to deposit on the active agent containing aerosol particle thus producing surface modified aerosol particles. The method can be used for batch or continuous production. Particles made according to the method and powders and dispersions containing the particles are also described.
