Oxidative dehydrogenation of ethylbenzene to styrene on activated carbons derived from a native wood as catalyst

Activated carbons were developed by phosphoric acid activation of a native wood (Prosopis ruscifolia) under a self-generated atmosphere or flowing air. Their potentiality as catalyst for oxidative dehydrogenation of ethylbenzene to styrene was examined at pre-established operating conditions. The ca...

Villaverde, M.S. Cukierman, A.L. Amadeo, N.E. Activated carbons Catalyst Ethylbenzene Oxidative dehydrogenation Styrene Activated carbons were developed by phosphoric acid activation of a native wood (Prosopis ruscifolia) under a self-generated atmosphere or flowing air. Their potentiality as catalyst for oxidative dehydrogenation of ethylbenzene to styrene was examined at pre-established operating conditions. The carbons developed in the self-generated atmosphere showedspecific surface area of 2281 m2/g and total pore volume of 1.7 cm3/g, whereas values of 1638 m2/g and 1.3 cm3/g, respectively, characterized those obtained in air. A commercial activated carbon (1200 m2/g and 0.7 cm3/g) was also used for comparison. Both wood-derived carbons resulted potentially suitable as catalyst for ethylbenzene oxidative dehydrogenation. Nevertheless, those developed in the self-generatedatmosphere showed a better catalytic performance than the carbonsobtained in air and the commercial sample. The behaviour could be due to its lower microporosity compared with the commercial sample, and to the formation of oxidative condensation products during the oxidative dehydrogenation of ethylbenzene with greater content of carbonyl groups than for thesample activated under flowing air. Chemical and textural characterization of the used carbons conclusively evidenced the presence of oxidative condensation products pointing to formation of new active surfaces. Fil:Cukierman, A.L.
