Abstract

This research experimentally investigated the impact of adding Carbon Coated Nickel and Carbon Coated Aluminium on the sorption performance of conventional Strontium Chloride-Natural Expanded Graphite (SrCl2-NEG) chemisorption composite. In order to evenly distribute Nano particles into the material, manufacture methodology is developed and reported. In this study, experiments were set for testing the sorption performance of applying novel Ni/Al-additive adsorbent with the working fluid of ammonia. Compared with that of SrCl2-NEG, Ni-additive adsorbent improves the comprehensive heat and mass transfer performance as it reacted faster in both adsorption tests and low temperature desorption tests. By adopting Carbon coated Ni into the chemisorption composite, the overall sorption cycle time and require relatively lower energy for sorption cycles. While Al-additive adsorbent only improves the reaction speed in low temperature desorption tests, and may be applied in negative catalyser for its bad behaviour in adsorption performance tests. This paper reveals that adding Carbon Coated Nickel into conventional chemisorption composite would provide a potential way for improving the overall efficiency of an adsorption system and reducing the overall sorption cycle time.
