H2S adsorption from biogas using natural Clinoptilolite

Adsorption of H2S by solids fixed in a bed column is the most efficient,environmental friendly, and economical process compared to other technologies. It can be studied through three different approaches; (1) Modeling (2) Laboratory scale experiments and (3) Pilot scale experiments. Many laboratoria...

description Adsorption of H2S by solids fixed in a bed column is the most efficient,environmental friendly, and economical process compared to other technologies.

Many laboratorial scale experiments proved that the Clinoptilolite is a promising medium to be used as an adsorbent of H2S from gas streams at low temperatures whereby few of them are focused to inspect usage of this material in its natural form. Using natural Clinoptilolite may results into a dramatic decrease of the adsorption process costs if its efficiency and performance during the process could be satisfied.
