Resumen:
Experiment design-response surface methodology (RSM) is used in this work to model and optimizetwo responses in the hydrogenation of tetralin to decalin using bimetallic Ir/Pt-SBA-15 catalyst. In thisstudy, we analyze the influence of the nature of the catalyst (metal molar fraction and metal loading),the catalyst/substrate ratio and the temperature of the reaction as factors for the design. The responsesanalyzed were conversion at 3 h and at 5 h of reaction time. The response surfaces were obtained withthe Box?Behnken design, finding the best combination between the reaction parameters that allowedoptimizing the process. By applying the statistic methodology, the higher levels of the two objectivefunctions were obtained employing the catalyst with 1 wt.% of iridium and 0.7-0.8 wt.% of platinum; theoptimal ratio between mass of catalyst and mole of tetralin was 17-19 g/mol and temperature between 200 and 220◦C.
