Abstract:
The first Emmett/Kokes award lecture.
William Curtis Conner, UMASS Chemical Engineering
In 1938 Paul Emmett and Steve Brunauer and Edward Teller developed an approach to analyze physical adsorption to extract and analyze a physical adsorption isotherm for N2 or Ar at their liquefaction temperatures to extract a monolayer volume from which a surface area, SA, could be estimated. The SA is a primary method by which catalysts and sorbents are characterized. Most recently, new materials including zeolites or metal organic frameworks, MOFs, have been developed that claim surface areas well exceeding 1000m2/g. Do these measurements and the application of the BET theory represent realistic estimates of actual surface areas, they don’t ? Finally, can physical adsorption also be employed to characterize diffusion within porous media? Frequency response measurements and their analyses are shown indeed to employ physical adsorption processes to analyze sorption and or transport in microporous solids.

We are proud to announce the creation of a new named lecture in the department of Chemical and Biomolecular Engineering: The Dr. Paul Emmett and Dr. Richard Kokes Endowed Lecture.
This ChemBE lecture is intended to be an annual interdisciplinary event with the department of Chemistry at Hopkins. Preference will be given to lecturers who have a focus on research in heterogeneous catalysis, which were Dr. Paul Emmett’s and Richard Kokes’ fields of expertise.
The inaugural lecture will be given in 2022 on Tuesday March 29 at 10:30am by Dr. William Curtis Connor Jr. (U. Mass, Amherst) who has generously endowed the Emmett-Kokes Lectureship. Dr. Connor received both his BS and PhD degrees in Chemical Engineering from Johns Hopkins. He has a storied career studying catalyst and nanocatalyst morphology and the production of biofuels by heterogeneous catalysts. He has contributed to catalytic kinetic theory and the development of several in situ studies of catalysis.
