Abstract

Lithium ortho-silicate is a suitable solid sorbent for capturing CO2. This reversible chemical reaction is applicable to CHP. Reaction rate of Lithium ortho-silicate are studied by TG (Thermogravimetry) and volumetric method that the influence of heat and mass transfer limitations at packed bed is designed as small as possible. CO2 adsorption reaction rate depends on the temperature. During continual operation, maximum reaction rate do not decrease for 10cycle and it turned out that the reaction system is repeated with from kept.The adsorbent utilization is higher than 60% at every condition. It turn out that lithium ortho-silicate is applicable to CHP.
