Douglas Patrick Harrison. Douglas Patrick Harrison (born in the 1900s) is a professor emeritus of chemical engineering from Louisiana State University's Gordon A. and Mary Cain Department of Chemical Engineering, where he taught undergraduate and graduate classes and served as a dissertation advisor to Ph.D. and M.S. students.

Biography
Douglas P. Harrison received his Ph.D. from the University of Texas in 1966. After three years with Monsanto, he joined Louisiana State University's chemical engineering department in 1969 as an assistant professor. Later, he served as department chair from 1976 to 1979, and then became the Alexis and Marguerite Voorhies Endowed Professor. In 2005, after 36 years of service with LSU, he retired from teaching.

Teaching
Harrison taught mostly undergraduate courses. After his time as department chair, he continued working closely with the chemical engineering graduate program as a doctoral and master's dissertation adviser. He has helped 10 Ph.D. students and 31 M.S. students complete their programs. He is the only professor to have received the Dow Chemical Excellence in Teaching Award four times (in 1988, 1995, 2000, and 2002).

Research
Harrison was a researcher with a focus on separation and reaction engineering. His work has primarily centered around non-catalytic gas-solid reactions and gas separation techniques associated with coal-fired power plants. He has also been involved in research related to the production of high-purity hydrogen, greenhouse gas removal from flue gas, and the separation of semi-volatile contaminants from aqueous solutions.

One of his research projects was "High-Efficiency Desulfurization of Synthesis Gas", where the aim was to improve the efficiency of reactions by removing hydrogen sulfide, a pollutant. Past research has included the use of Sorbent CeO2-ZrO2 to reduce hydrogen sulfide content. 

Dr. Harrison's research also extended to the reduction of CO2 emissions from flue gas using regenerable reagents. This research aimed to develop an economical solution for retrofitting existing power plant stacks to mitigate carbon dioxide emissions, which are associated with global warming. 

Additionally, Dr. Harrison has been involved in exploring innovative hydrogen production methods in collaboration with Professor Armando Corripio, NASA, and TDA. Their research focuses on achieving 95+% hydrogen production using a single reactor, streamlining the process that previously required three vessels.

Moreover, Dr. Harrison holds a patent, jointly with Klaus S. Lackner and Hans Zoick, for hydrogen production from carbonaceous materials.

Awards and patents
