Production of styrene by dehydrogenation of ethylbenzene on a [Re, W]/γ-Al2O3 (K, Ce)/α-Al2O3 porous ceramic catalytic converter
Résumé
This paper presents the results of a study on the particularities of the process of dehydrogenation of ethylbenzene to styrene over an original [Re,W]/gamma-Al2O3 (K, Ce)/alpha-Al2O3 porous ceramic catalytic converter, obtained by self-propagating high-temperature synthesis and the sol-gel method. It was found that, over this converter, the output of styrene, with a similar to 100 % selectivity to liquid products, is similar to 23 times higher than that over the same conventional bulk of industrial catalysts. Further, after 6 h of reaction, the degree of carbonization of the converter does not exceed 5 wt.%.
