Liquid phase reaction process

摘要

Process and apparatus are described for the decomposition of reactants, e.g. hypochlorite ions, contained in a liquid stream into a gaseous product, e.g. Oxygen, by contact with a particulate catalyst disposed in a plurality of reaction volumes 4a-f connected in series. The flowrate of the gaseous product is required to be at least 0.5 that of the liquid stream, and the vertical velocity of the gaseous product is limited to less than 5 cm.s<-1>. The reactor 1 is divided into the volumes 4a-f by a series of baffles 10. Within the volumes the liquid forms free surfaces 7a-f from which the gas escapes. In an alternative (Fig 2, not shown) the successive volumes are each lower than the preceding one.
