摘要：

The kinetic parameters were obtained by adsorption isotherm, and the CFD model was established to simulate the adsorption process of hydrogen/nitrogen in the structured 5A molecular sieve adsorption bed. The effects of structural parameters such as the adsorbent sheet spacing and thickness and process parameters such as adsorption pressure and volume flow rate on the adsorption performance to the mixed gas were discussed. The results show that reducing sheet spacing and thickness are beneficial to the mass transfer coefficient and bed saturation degree. Increasing the adsorption pressure can improve the bed saturation degree, but will reduce the mass transfer coefficient. The effect of the flow rate on mass transfer coefficient is not obvious, but when the flow rate is high, both the adsorption capacity and the bed saturation degree decrease. The structured 5A molecular sieve adsorbent has good adsoption performance. © All Right Reserved.
