Design of Structured Catalysts Based on Metallic Monoliths for Syngas Production via Partial Oxidation of Natural Gas

Structured catalysts based on metallic supports of different types with a high thermal conductivity were designed. The metal monolithic supports were made from a heat-resistant foil or gauze coated with a protective layer of Al 2 O 3 or zrO 2 using blast dusting. To prepare catalysts, Ce-Zr-La-O and LaNiO x promoted with Pt were successively supported on monoliths. A high and stable performance of these catalysts in the partial oxidation of methane (POM) at short contact times in the autothermal mode was demonstrated. In the reactor with a heat exchanger these catalysts operate in the autothermal mode without any heat preheat at very high gas velocities.
