Abstract

Interest in partial oxidation (POX) has expanded because emissions reduction is a key topic in research and design of industrial processes. For example, hydrogen production from renewable sources is an important research area worldwide. POX processes operate with non-stoichiometric fuel-to-air mixtures, at high temperatures and elevated pressures. Catalytic partial oxidation (CPOX) enhances reactions; therefore operating temperature and pressure can be decreased. Problems include hot spots and poor heat conductivity in catalyst beds during very exothermic reactions. Efforts have been made to solve these problems in partial oxidation: fluidized bed reactors and using endothermic reactions such as steam reforming with POX. Catalysts based on nanomaterials and reactor systems using membranes, photocatalysis and microreactors have been developed to advance POX processes.
