Intensification of gas phase catalytic processes in nanochannels of ceramic catalytic membranes

In the present work the metal-ceramic catalytic membranes with gradient porosity in the range of 2–3000 nm pore size were obtained. Proposed structural design of membranes including the combination of catalytic coatings inside of membrane channels with a top coating of a mesoporous metal oxide layer exibits an anisotropy in the catalytic reaction and gas permeationcorrelating with an improved hydrogen production. Modified high temperature ceramic membranes provide the high speed methane and CO2 conversion into syngas and light hydrocarbons at 500–650°C, showing a good potential for systematic study of intensification effects in membrane catalysis.
