A new experimental system was developed for making hydrogen by hydrolyzing Zn nano-particles in a cyclone reactor

in which the chemical reaction and gas-solid separation were accomplished simultaneously.The research showed that the Zn nano-particles via 11 h milling reacted with steam rapidly at a lower temperature of 250℃ because of its excellent performance.The gas-solids formed a three-dimensional

turbulent flow-field induced by strong revolving force.The turbulent motion of the particles improved the efficiency of heat and mass transfer and increased chemical reaction rate

and the device allowed for simple

continuous removal of products in a turbulent flow field.The solid phase product was a peculiar structure of bar and flake

which could achieve a degradation rate almost 100% of organic matter in polluted water.
