Production of styrene by dehydrogenation of ethylbenzene on a [Re, W]/γ-Al2O3 (K, Ce)/α-Al2O3 porous ceramic catalytic converter

•Dehydrogenation of ethylbenzene to styrene on Re-W catalysts.•Self-propagating high-temperature synthesis for preparation of porous ceramics.•Sol-gel method for efficient formation of homogeneous coatings of nanocatalysts.•Improving the efficiency of catalytic processes on structured catalysts.•Low coking of catalysts in dehydrogenation processes.
