Abstract
Experiment design-response surface methodology (RSM) is used
in this work to model and optimize two responses in the
hydrogenation of tetralin to decalin using bimetallic Ir–Pt-SBA-15
catalyst. In this study, 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 responses analyzed were conversion
at 3 h and at 5 h of reaction time. The response surfaces were
obtained with the Box–Behnken design, finding the best
combination between the reaction parameters that allowed
optimizing the process. By applying the statistic methodology, the
higher levels of the two objective functions were obtained
employing the catalyst with 1 wt.% of iridium and 0.7–0.8 wt.% of
platinum; the optimal ratio between mass of catalyst and mole of
tetralin was 17–19 g/mol and temperature between 200 and 220
◦C.
