optimization of spray pulse reactor conditions used for dehydrogenation of liquid organic hydrides by using response surface methodology

Dehydrogenation of liquid organic hydrides is the key reaction for the process where these hydrides are viewed as a potential candidate for hydrogen storage and delivery application. methylcyclohexane is used as a liquid organic hydride for dehydrogenation reaction. using a spray pulse reactor, we determine the possible reaction conditions for the greatest percentage conversion of methylcyclohexane during dehydrogenation and hence maximal hydrogen evolution with the help of response surface methodology. the suggested regression model with independent variables based on the box-behnken design is explained using an analysis of variance. r2 and r2adj correlation coefficients of 0.90 and 0.74 are used in this model. the estimated optimum conditions for percentage conversion of methylcyclohexane in this study are 389 °c temperature, 14 sec pulse frequency interval, and 1 ms pulse width where 44.51 % conversion of methylcyclohexane is expected. this was confirmed by the actual experimental value of  46.36 % conversion of methylcyclohexane during dehydrogenation using a 5 wt% pt/ activated carbon cloth catalyst. the entire study demonstrates that the box-behnken design combined with response surface methodology may be utilized to efficiently optimize the reaction conditions of a spray pulse reactor during methylcyclohexane dehydrogenation with 5 wt% pt/activated carbon cloth catalyst.
