Chinese researchers from the Shanghai Advanced Research Institute and Fudan University have developed a catalytic process that converts polyolefin plastics into jet fuel components. Using a nickel-cobalt catalyst, the method achieves a liquid product yield of 82.3% with 79% selectivity toward C8-C16 hydrocarbons, the key building blocks of aviation fuel. The reaction runs at 280°C and 3 MPa hydrogen pressure, avoiding expensive noble metals used in earlier approaches. The process could cut greenhouse gas emissions by up to 80% compared to conventional jet fuel production if powered by renewable energy. However, the technology is still at the lab stage. Key hurdles include scaling up, handling mixed plastic waste, and managing contamination that can degrade the catalyst. Researchers say reliable pre-treatment methods will be needed before commercial deployment.
