摘要

开发一套全新的纳米锌粉水解制备氢气的实验装置，采用旋流反应器同时完成化学反应和气固分离过程，节省分离设备所需投资。研究表明：研磨11 h的纳米锌结构具有优异的性能，可使反应在较低温度下迅速完成;反应温度为250℃时，固体颗粒的转化率为89%，固相产物氧化锌与未完全反应的锌形成棒状与片状共存的独特结构;旋流反应器内气流带动颗粒作高速旋转运动，改善质量传递和热量传递过程，加快反应进程，颗粒夹带在气流中，可以简单、连续、可控地进出料，有利于工业化应用。

Abstract

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.
