METHOD FOR PRODUCING HYDROGEN PEROXIDE BY DIRECT SYNTHESIS

Номер: KR20010042605A
Принадлежит:

The invention relates to a method for producing an aqueous solution of hydrogen peroxide from hydrogen and oxygen by direct synthesis in the presence of a heterogeneous catalyst. According to this method, a mixture containing H2and O2is supplied to the reactor which contains the catalyst. Said gas mixture is essentially saturated or oversaturated (= containing mist) with water vapour. The volume ratio of gas mixture (Nl/h) supplied to liquid (l/h) taken off is adjusted to values equal to or greater than 15,000, especially 20,000 to 50,000 and the gas mixture leaving the reactor is re-stocked with H2, O2and H2O vapour and recycled. According to the invention, solutions with a high concentration of H2O2can be obtained without any further concentration. © KIPO & WIPO 2007 ...

PROCESS AND DEVICE FOR CARRYING OUT REACTIONS IN A REACTOR WITH SLOT- SHAPED REACTION SPACES

Номер: KR20030065470A
Принадлежит:

Reactions between at least two fluid reactants are performed in a reactor comprising wall elements (1), slot- shaped reaction spaces (3) and cavities (5) for conducting a fluid heat- carrier through. Depending on the process and throughput, a modular structural design is chosen wherein an arbitrary number of wall elements (1) are assembled to a right-parallelepipedal block (24), the reaction spaces (3) are formed between lateral surfaces (2) of right- parallelepipedal wall elements (1), the reactants are introduced into the reaction spaces (3) from edge regions of one side of the block (24) and are conducted through the reaction spaces (3) in parallel flows and the fluid heat-carrier is conducted through the tubular cavities (5) extending in the interior of the wall elements (1). © KIPO & WIPO 2007 ...
