Natural gas (with methane as its main component) provides an attractive energy source because of its large abundance and its high heat of combustion per mole of carbon dioxide generated. However, the emissions released from the conventional flame combustion (essentially NOx) have harmful impacts on the environment and the human health. Within the scope of rational and clean use of fossil energies, the catalytic combustion of natural gas appears as one of the most promising alternatives to flammable combustion. The presence of catalysts enables complete oxidation of methane at much lower temperatures (typically 500 °C), so that the formation of pollutants can be largely avoided. This work presents a literature review on the catalytic methane combustion. Various aspects are discussed including the catalyst types, the reaction mechanisms and kinetic characteristics, effects of various influencing operational factors and different reactor types proposed and tested. This paper may serve as an essential reference that contributes to the development of well-designed reactors, equipped with appropriate catalysts, and under well-handled operating conditions to realize the favorable (kinetic) performance, for their future applications and propagation in different industrial sectors.

In the past decade, the use of TiO 2 as a photocatalyst has received much attention in the treatment of wastewater. Because of their large specific surface area, mostly particles in the nm-range are used in slurry reactors. Such systems show excellent performance, but it is difficult to separate the catalyst from the treated water. To overcome this drawback, titania powder has been immobilized or directly synthesized on a support by CVD or wet-chemical methods (1-4). Light-transmittant particles (d 100 μm) are especially promising as carriers, since they provide a high surface area and can be used in mass-transfer free reactor systems, such as fluidized beds.
