Abstract: PROBLEM TO BE SOLVED: To provide a doping-processed titanium dioxide capable of being sued as a photocatalyst, an UV absorber and for effluent and exhaust cleanup and its manufacturing method and its use. SOLUTION: When titanium dioxide is manufactured by pyrolysis and processed with an aerosol, a metal salt solution is sprayed and supplied to the manufacturing line as the aerosol. The doping-processed titanium dioxide which contains the oxide in the group of zinc oxide, platinum oxide, magnesium oxide and/or aluminum oxide as the doping component is manufactured.

Abstract: Two reactants are introduced into a slot-shaped reaction space (3) of a reactor. The space is formed between lateral surfaces (2) of two equally large and right parallelepipedal wall elements (1) comprising solid plates. The reactants are introduced from the edge of the slot-shaped reaction spaces situated on the same side of the block. Two reactants are introduced into a slot-shaped reaction space of a reactor. The spaces are formed between lateral surfaces of two equally large and right parallelepipedal wall elements comprising solid plates. The wall elements are arranged interchangeably in a block within the virtual parallelepiped. The reactants are introduced from edge regions of the slot-shaped reaction spaces situated on the same side of the block. The reactants are conducted as a reaction mixture through the reaction spaces in the same direction in parallel flows. A fluid heat exchange medium is conducted through tubular cavities (5) extending in the interior of the wall elements to obtain the desired reaction. An independent claim is also included for apparatus comprising the reactor in which the slot-shaped reaction spaces are capable of having the reactants supplied from the same side of the block. The reaction spaces are oriented to guide the reaction mixture in the same direction in parallel flows.

Abstract: An aqueous solution of hydrogen peroxide is produced by direct synthesis from hydrogen and oxygen in the presence of a heterogeneous catalyst. According to the invention, a gas mixture comprising H2 and O2, essentially saturated or supersaturated with water (=containing fog) is fed into a reactor containing the catalyst. The volume ratio of the gas mixture fed in (standard liters per hour) to liquid removed (liters per hour) is adjusted to a value equal to or greater than 15,000, especially 20,000 to 50,000, and the gas mixture leaving the reactor is recycled after replenishment with H2, O2, and H2O vapor. Solutions with high H2O2 concentration can be obtained according to the invention without additional concentration.

Abstract: In direct synthesis of hydrogen peroxide from hydrogen and oxygen using a heterogeneous noble metal catalyst and optionally solvent, the catalyst is based on palladium or NOTLESS 2 metals of the platinum group and sub-group I. In direct synthesis of hydrogen peroxide from hydrogen and oxygen using a heterogeneous noble metal catalyst and optionally solvent, the catalyst is based on palladium or NOTLESS 2 metals of the platinum group and sub-group I. It is produced by passing particles of a solution or suspension of metal compound(s) in a carrier gas into a spray or flame pyrolysis reactor and separating the resultant metal or alloy particles from the gas stream.
