Investigation of zeolites for CO2 and H2S adsorption

Nowadays with the advancement of industry, more greenhouse gases specially CO2 are being emitted to the atmosphere, therefore it leads to some massive environmental issues such as global warming. In addition to the harmful environmental effects of CO2, presence of this gas with H2S in natural gas contribute to low heating value and furthermore corrosion of process equipment due to the high acidity of these gases. One of the effective industrial methods is utilizing amine and ammonia solutions for absorbing and carbon capturing. however, due to its drawbacks and also advantages of adsorption process specially zeolite adsorbents, adsorption has drawn researchers’ attention. In this context, will be discussed about some zeolite adsorbents which are used for CO2 and H2S adsorption and discussion about mechanisms of H2S adsorption on FAU, LTA, and 13X zeolites.
