Abstract

Hydrogen stored in liquid organic hydrogen carriers (LOHCs) like dibenzyltoluene makes it a simple and safe technology along with long term storage. In this study, a preliminary study regarding the dehydrogenation of perhydro-dibenzyltoluene with switching from a stirred batch reactor to a continuous flow microchannel reactor is presented. The performance of the reactors was investigated with a 2% Pt/Al₂O₃ catalyst. The hydrogen production percentage in the case of a continuous flow microchannel reactor was found higher (58% hydrogen production) when compared to that of a stirrer type reactor (only 12% hydrogen production) in 12 hours of operation. Moreover, the effect of microchannel bottom plate temperature on the hydrogen production was also investigated. The hydrogen production was increased from 64.15% to 82.20% with the increase in bottom plate temperature from 260 to 320°C for 0.01 mL/min flow rate of H18-DBT and 20 hours experiment. With the increase in the operating time, the hydrogen production found to increase slowly. A maximum of 88% of hydrogen was generated for a 40 hours' operation, at a bottom wall temperature of 290°C. The results revealed that a continuous microchannel reactor can be an appropriate technology for the dehydrogenation of H18-DBT.
