  • Patent number: 11123702
    Abstract: A turbomachine type chemical reactor for processing a process fluid is presented. The turbomachine type chemical reactor includes at least one impeller section and a stationary diffuser section arranged downstream. The impeller section accelerates the process fluid to a supersonic flow. A shock wave is generated in the stationary diffuser section that instantaneously increases static temperature of the process fluid downstream the shock wave for processing the process fluid. Static pressure of the process fluid is simultaneously increased across the shock wave. The turbomachine type chemical reactor significantly reduces residence time of the process fluid in the chemical reactor and improves efficiency of the chemical reactor.
