The catalyst-assisted chemical heat pump (CHP) system for temperature upgrading, constituted with reversible ndothermic methylcyclohexane and exothermic toluene hydrogenation reactions together with the functions of separation and heat storage, was presented. Accoding to Aspen Plus process simulation, the system thermal efficiencies from 200℃ to 250℃ and 300℃, were estimated as 72.3% and 68.2% respectivery. Exergy analysis on this CHP system was performed in terms of exergy loss due to heat dissipation and of exergy gain from evaluated to be null in exergy.
