Abstract

The effect of the competitive adsorption of H2S, Water and CO2 on molecular sieves 13X is here reported. The uptake of trace amounts (100 ppmv) of H2S was experimentally calculated by means of short term breakthrough tests either in the presence of small percentages of water (0.2 % vol.) or biogas type concentrations (35 % vol.) of carbon dioxide. Results show that in the absence of water, the adsorption process is substantially enhanced, thus the molecular sieves can be successfully employed both for sulphur clean up and carbon dioxide capture.
