The hydrogen release process via thermochemical dehydrogenation (TCD) was demonstrated using IPA TCD reaction. TCD reactions typically occur at higher operating temperatures than hydrogenation reactions owing to their endothermic nature. Higher operating temperatures will result to higher energy consumption for favorable reaction conditions. IPA TCD used to be the main process for the industrial production of acetone and was later replaced by cumene oxidation as the main acetone production process which has cheaper raw materials and also co-produces phenol as a valuable product. However, IPA TCD is still currently deployed in a minor extent to produce acetone with high purity. IPA TCD can be utilized for the hydrogen release during the LOHC cycling process. IPA TCD has been reported to occur at temperatures in the range of 200°C to 450°C and at atmospheric pressure using a fixed bed reactor. In this work, IPA TCD was simulated using Aspen Plus and the process flow is shown in Figure and Figure . Stream (S-11), containing 1kmol/hr of IPA at 25℃, was heated up to 420℃ before entering the reactor as stream S-12. The reaction conditions used were adopted from patent literature where 90% conversion and 99% selectivity were observed on a Cu/Zn/Cr/Al2O3 trimetallic catalyst. In this simulation, the reactor was operated at 420°C and 0.1MPa. The feed was preheated to the reaction temperature before entering the reactor. The reactor was modelled as an isothermal RStoic producing a 90% conversion and 100% selectivity. The simulation results showed that IPA TCD requires more energy than the acetone TCH due to high operating temperatures and the reaction being endothermic. The energy required to heat the feed to the reaction temperature was 96900kJ/hr. Moreover, 53900kJ/hr was required for the reactor to maintain the reaction temperature.
