Apparatus and method converting feedstock (e.g., chicken litter) into oil, gas, and ash fertilizer has a reformer unit with (i) a feedstock input, (ii) an outer wall, (iii) a reaction chamber with an inner wall, (iv) a combustion gas input, (v) a scrubbing liquid input, (vi) a feedstock stirrer, (vii) an ash stirrer, (viii) an ash plate below the reaction chamber, and (ix) a combined liquid / gas output. The ash plate is separated from the inner wall. Feedstock and scrubbing liquid are preferably reacted within the reaction chamber to release useful hydrocarbon liquids and gasses which migrate to the top of the reformer, while ash from the reaction falls onto the ash plate from where it is output. Liquid / gas pump structure sends the combined liquid / gas from the reformer to gas / liquid separator structure which provides a gas output and a liquid output. The gas output may be used, flamed off, and / or recirculated to the reaction chamber. Oil / water separator structure receives the liquid output and provides a (e.g., scrubbing) water output and an oil output. Processor structure controls the various motors, valves, etc., to control the inputs / outputs and the temperature of the reformer so as to cause an electric current to flow upward along the inner wall and inward toward the reaction product within the reaction chamber to cause arcing in the feedstock; which arcing disassociates molecules into atoms, thus releasing more energy. The oil is refinable, the gas is high in energy content, and the ash fertilizer is high in nitrogen.

A process is disclosed for forming a nanosize ceramic powder. A precursor ceramic material is formed of a fugitive constituent and a non-soluble constituent in a single phase. The precursor is contacted with a selective solvent (water, acid, etc.) to form a solution of the fugitive constituent in the solvent and a residue of the non-soluble constituent. The precursor is sufficiently reactive with the solvent to form the solution of the fugitive constituent in the solvent and form the nondissolved residue of the non-soluble constituent. The precursor material and the non-soluble residue are sufficiently insoluble in the solvent such that there is insufficient precursor material and non-soluble residue in solution to deposit and precipitate upon the residue of the non-soluble-constituent. The fugitive constituent is sufficiently soluble in the solvent such that the precursor reacts with the solvent to form the solution of the fugitive constituent without precipitation and deposition of fugitive constituent upon the residue of the non-soluble constituent in the form of nanosize particles. After the fugitive constituent is dissolved the selective solvent containing the fugitive constituent is removed from the residue. The residue remains in the form of a nanosize powder of the non-soluble constituent.

The fugitive constituent can be leached from the metallic precursor to leave a metallic residue which is a mass of nanosize metallic particles made substantially of the target metal. The nanosize metallic particles can then be recovered from the metallic residue either merely by removing the solvent and / or breaking up the mass of nanosize metallic particles. The disclosed methods allow for a convenient avenue for production of nanosize particles from readily formed materials for use in a wide variety of potential industrial and commercial applications.
