The world’s energy demand is continuously increasing due to the rapid increase in population and technology. Because of this high demand, nonrenewable fossil fuels are being used and the requirement for reducing greenhouse gasses is increasing. Dry reforming of methane (DRM) is a promising technology which uses two greenhouse gasses, CO and H2, to create syngas, a combustible fuel. Currently, the DRM reaction is carried out at high temperatures in the presence of catalysts. However, there is currently a global challenge to develop a thermally stable and active catalyst that can carry out the reaction at reduced temperatures.
Researchers at the University of Wyoming have invented a Ce1xTixO2 supported nickel catalyst to be used in DRM. The catalyst is made using the sol-gel technique. This is a way of getting a gelatinous material out of a liquid at room temperatures. This catalyst works in DRM at temperatures as low as 600 °C and can last for up to 50 hours without showing much activity loss. The CH4 conversion and H2 yield for the DRM reaction is 68% and 47% respectively. The overall study of this catalyst suggests that it is active and stable enough for dry reforming methane in industrial applications.
This technology can be used to dry reform methane much more economically. Because the catalyst lowers the temperature of the reaction and last for a long time without much activity loss, much less energy needs to be put into the reaction.
