Biography

Dr. David J. Heldebrant is a Chief Scientist and Team Lead of the Separations Materials team under the Advanced Energy Systems Group in the Energy Processes and Materials Division at Pacific Northwest National Laboratory. Dr. Heldebrant joined PNNL as a post-doctoral research scientist in 2005.

Research Interests

  • Dr. Heldebrant's current research focuses on applying the principles of Green Chemistry to improve atom and energy efficiency and reduce toxicity of chemical processes and to make energy-related process more environmentally benign. Focus areas are on developing materials that can perform multiple tasks to reduce waste and improve energy efficiency in the fields of chemical separations and chemical conversions, applying these principles in areas of industrial gas separations, liquid/liquid separations and catalysis. The work focuses on the development of organic gas-separating liquids that can chemical remove CO2, SOx, and H2S from combustion, gasification or natural gas streams through applied and fundamental studies of gas absorption kinetics, thermodynamics and mechanistic studies.
