Abstract
Oxygen concentration profiles in bed for O3 generation from air by vacuum pressure swing adsorption (VPSA) in pressure equalization, raising pressure and adsorption Process were studied on a two-bed VPSA pilot unit under different vacuum pressures and product 02 concentrations. The results showed that a VPSA Process with incomplete pressure equalization was needed in equalization step to keep the O2 concentration at the top of bed over the O2 concentration of air; the higher of product O2 concentration, the lower of equalization pressure; and the lower of vacuum pressure, the higher of equalization pressure. Effect of product O2 concentration on O2 concentration in the bed was more evident than vacuum pressure in raising pressure and adsorption Process. The higher the product 0; concentration, the higher the O2 content of bed. There was a wall effect of adsorption bed and O2 concentration of wall was lower than that in the radial center of bed.关键词
