Abstract: In one embodiment a porous partition having predetermined porosity and predetermined photocatalytic properties is formed by mixing particles of photocatalytic material with particles of structural material, forming the particle mixture into a predetermined shape, applying pressure to the formed particle mixture, and heating the formed particle mixture to a predetermined temperature in a predetermined atmosphere. In another embodiment, the particles of structural material and the particles of photocatalytic material are separately formed, pressurized and heated, after which the sintered photocatalytic article is joined to the sintered structural article. In yet another embodiment a sol-gel comprising a metal oxide semiconductor and an organic component is drawn into the pores of a porous stainless steel layer and is thereafter heated to oxidize the organic component leaving the semiconductor in the pores of the stainless steel.

Abstract: In a method of improving the quality of diesel fuel, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into diesel fuel, after which the treated fuel is recovered. The oxidizing gas is preferably ozone and is utilized immediately upon its manufacture. By means of the method, sulfur is removed from the diesel fuel and the cetane rating thereof is increased.

Abstract: In a method of removing organic contaminants from a liquid, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into an initially contaminated liquid, after which the treated liquid is recovered. The oxidizing gas is preferably selected from a group including ozone and chlorine dioxide and is utilized immediately upon its manufacture. An oxidizing liquid may be employed in conjunction with the oxidizing gas.

Abstract: In a method of and apparatus for producing sub-micron bubbles in liquids, slurries, and sludges, gas is maintained on the interior of the gas permeable partition at predetermined pressure. Relative movement between the gas permeable partition and the surrounding material forms sub-micron sized bubbles in the liquid, slurry, or sludge.

Abstract: In a method of removing acidic compounds, color, and polynuclear aromatic hydrocarbons, and for removing or converting hydrocarbons containing heteroatoms from petroleum distillates, phase transfer catalyst is employed to facilitate the transfer of inorganic or organic bases to the substrate of the distillate. An inorganic or organic base, a phase transfer catalyst selected from the group including quaternary ammonium salts, polyol ethers and crown ethers, and used oil distillate are mixed and heated. Thereafter, contaminants are removed from the used oil distillate through distillation. A solvent is then mixed with the resulting distillate to extract contaminants therefrom. The solvent is recovered and distilled to separate the contaminants therefrom, and is then reused. The petroleum distillate having the contaminants separated therefrom is also distilled to remove any remaining solvent therefrom, with the recovered solvent being reused.

Abstract: In a method of and apparatus for manufacturing methanol and higher alcohols from natural gas a catalytic area is formed on the exterior of a gas permeable partition. Natural gas is maintained on the interior of the gas permeable partition at predetermined pressure. Relative movement between the gas permeable partition and the water forms sub-micron sized bubbles of natural gas. Electromagnetic radiation is directed onto the catalytic surface to form hydroxyl radicals from the water. Methyl, ethyl, and propyl ions from the natural gas combine with the hydroxyl ions to form methanol, ethanol, and propanol.

Abstract: In a method of and apparatus for manufacturing methanol from methane a catalytic area is formed on the exterior of a hollow sintered stainless steel tube. Methane is maintained within the sintered stainless steel tube at predetermined pressure, and water continuously flowing across the exterior surface thereof strips the methane forming sub-micron sized methane bubbles. Ultraviolet light energy is directed onto the catalytic surface to form hydroxyl radicals from the flowing water. The hydroxyl radicals cleave the carbon-hydrogen bonds of the methane to form methyl ions which combine with the hydroxyl ions to form methanol.
