Abstract
A new type of glass-tub nanophotocatalytic reactor was designed for controled-atmosphere(CA) storage to decompose and remove ethylene gas efficiently. The key design parameters of the reactor model were simulated and analyzed through experiment. The results show that the ethylene-removing efficiency of photocatalytic reactor mainly depends on the flow rate of gas, the diameter and length of the glass tube and the radiation resource. The favorite conditions keeping photocatalytic reactor in higher efficiency state in this experiment were shown as follows: the flow rate of gas was in the range of 40~80 L/h; the diameter of glass tube was about 50 mm; black light lamp was better than the purple UV lamp; and two same glass pipes in series were better than the single one. The experimental results provided some important basic parameters for the design of high-efficiency ethylene decomposition equipment for CA storage.
