Title: Innovations of David A Russell in Pyrolysis Technology
Introduction
David A Russell is an accomplished inventor based in Kirkland, WA (US). He holds a total of 4 patents, showcasing his significant contributions to the field of pyrolysis technology. His innovative approaches have the potential to revolutionize the way feedstocks are processed.
Latest Patents
One of his latest patents is a method for initiating pyrolysis using a shock wave. This apparatus establishes a continuous, standing shock wave to initiate the pyrolysis of a feedstock. Several embodiments of a shock wave reactor are disclosed, each designed to receive an ethane feedstock and a carrier fluid comprising superheated steam. The feedstock and carrier fluid are pressurized, allowing them to expand into parallel supersonic streams that mix due to turbulence within a mixing section of the reactor. The carrier fluid heats the ethane feedstock, producing a mixture that flows at supersonic velocity down the channel. A gate valve downstream provides controlled back pressure, affecting the position of the shock wave and the residence time for the reaction. The shock wave rapidly heats the mixture above pyrolysis temperature, enabling a residence time of only 5 to 50 milliseconds. This innovative approach allows for maximum yield from different feedstocks by varying the position of the shock wave. The mixture is then quenched downstream, cooling and terminating the pyrolysis reaction, which highlights the advantages of the shock wave reactor.
