Study of the effect of organic binders on 13X zeolite agglomeration and their CO2 adsorption properties

Abstract

The aim of the present research is to shape zeolite 13X and study the effect of singular and binary systems of binders. For this purpose, zeolite 13X was successfully synthesized under hydrothermal conditions. Different combinations of polyvinyl alcohol (PVA) and polyethylene glycol (PEG) were used for shaping. Physical properties of granules were measured by nitrogen adsorption-desorption, and results showed that increasing the binder content up to a certain amount enhanced the physical properties. However, the surface area decreased with a further increase in binder content. In addition, it was found that mechanical strength was decreased with increasing binder content after burnout.
