North Carolina State University is looking for commercial partners to license and commercialize a novel oxidative cracking process, utilizing novel catalysts, which operates at lower than standard temperatures.
Olefins and diolefins are important for the petrochemical industry. Demand for olefins is increasing, driving a desire for efficient production from a broad range of feedstocks, such as naphtha and stranded natural gas liquids. However steam cracking, the current industrial approach, requires temperatures up to 1200 °C to drive the reaction, which consumes large amounts of energy. This makes the process difficult to employ economically on a small scale.
Researchers at North Carolina State University have developed a novel system of catalysts for oxidative cracking, in a chemical looping- oxidative dehydrogenation process. An oxygen- carrying bulk material that is active in the temperature range 500-825 °C with a modified surface. The catalyst is doped, in order for hydrogen to be selectively combusted over low boiling point hydrocarbons. This technology can be converted to other selective oxidations with different surface/bulk modifications.
- Can be extended to other selective oxidations
- Regenerates in air or other oxidizing gas
- Highly efficient process with significantly lower emissions
- Works at low temperature 500 - 825 °C
