THERMOCHEMCIAL METHANE REFORMING USING WO_3 AS AN OXIDANT BELOW 1173 K BY A SOLAR FURNACE SIMULATOR

摘要

Thermochemical methane reforming by a reactive redox system of WO_3 was demonstrated under direct irradiation of the metal oxide by a concentrated, solar - simulated Xe-lamp beam below 1173 K, for the purpose of converting solar high-temperature heat to chemical fuels. In the proposed cycling redox process, the metal oxide is expected to react with methane as an oxidant to produce syngas with a H_2/CO ratio of two, which is suitable for the production of methanol, and the reduced metal oxide which is oxidized back with steam in a separate step to generate hydrogen uncontaminated with carbon oxide.
