US Breakthrough Tech Converts CO2 into Clean Energy: Catalyst Developed by ORNL Boosts Syngas Production

A breakthrough technology developed by Oak Ridge National Laboratory (ORNL) is poised to change the production of clean energy from its reliance on harmful greenhouse gases such as methane and carbon dioxide (CO2). This revolutionary process, called dry reforming of methane, holds a great potential for changing CO2 into useful products. The first of these products is syngas-a mixture of hydrogen and carbon monoxide, which is one of the most important building blocks for producing fuels and chemicals.

Dry reforming of methane is a highly energy-intensive process, which has always been plagued by the high temperatures needed to start and maintain the reaction. At 650°C (1,200°F), traditional catalysts suffer from problems such as sintering, which decreases the catalyst's interaction with reactants, and coking, where carbon deposits strangle the catalyst.

However, ORNL’s team has developed a new catalyst that overcomes these challenges. By using a crystalline zeolite framework doped with nickel, along with silicon, aluminum, and oxygen, the new catalyst can withstand the high temperatures without deactivating. Zeolite, a porous crystalline material, provides a vast surface area, enabling numerous interactions between reactants. This results in a much more efficient process for converting methane and CO2 into syngas.

The ORNL catalyst is demonstrated to be very efficient with outstanding catalytic activities and high stability in methanization and carbon dioxide: ensuring their conversion into syngas without any by-product harmful species. In contrast with traditional methane steam reforming, that needs water and emits CO2, the dry reforming uses methane and CO2 directly thus making the production of syngas more sustainable and highly water saving.

This innovation may have a significant impact on the environment and industries. CO2 can be used to create syngas, thereby opening up a new opportunity to reduce greenhouse gases while providing useful raw materials for the chemical industry. ORNL has developed a novel catalyst for the recycling of CO2 into energy to help mitigate climate change and address global energy needs.
