摘要：

H2S adsorption from dilute streams containing He, N-2, CO2, CO, and H2O was studied experimentally and by simulations for zeolites X and Y to evaluate their potential for Claus tail gas sulfur removal. Ag-X and Y were able to remove H2S in presence of all other species. CuX and CuY were efficient in removing H2S in the presence of N-2. CO2, and water vapor but failed to remove H2S in presence of 2% CO. In agreement with the experimental findings, simulation results showed that Ag(I)-exchange leads to the most promising faujasite sorbent for H2S, whereas Cu(I) is subject to strong adsorption of CO, and Na, and Cu(II) are subject to strong adsorption of H2O.
