Title: The Innovative Contributions of Robert L Braun
Introduction
Robert L Braun is a notable inventor based in Livermore, CA (US). He has made significant contributions to the field of oil shale retorting, holding a total of 3 patents. His work focuses on innovative processes and apparatuses that enhance the efficiency of oil shale extraction.
Latest Patents
Braun's latest patents include an "Apparatus for oil shale retorting" and a "Process for oil shale retorting using gravity-driven solids flow." The apparatus involves a cascading bed retorting process where cold raw crushed shale enters the middle of a retort column. In this system, the shale is rapidly mixed with hot recycled shale, heating it to pyrolysis temperature. The heated mixture then passes through a pyrolyzer stage, allowing complete pyrolysis to occur. The spent shale is recirculated through a burner stage, where the residual char is burned to heat the shale before it re-enters the mixer stage.
Career Highlights
Throughout his career, Braun has worked with esteemed organizations, including the United States of America as represented by the United States Department. His innovative approaches have contributed to advancements in oil shale technology.
Collaborations
Braun has collaborated with notable individuals such as Richard G Mallon and Otis Raymond Walton. Their combined expertise has furthered the development of effective oil shale retorting processes.
Conclusion
Robert L Braun's contributions to the field of oil shale retorting demonstrate his commitment to innovation and efficiency. His patents reflect a deep understanding of the complexities involved in the extraction process, making him a significant figure in this area of research.
