675 Catalyst Deactivation

Thursday, November 20, 2014: 12:30 PM
307 (Hilton Atlanta)
Description:
This session will focus on measuring and characterizing catalyst degradation, determining degradation modes, modeling deactivation and predicting catalyst performance and characteristics after deactivation. Presentations are expected to include discussion of new deactivation characterization tools; surface characterization of catalysts describing surface chemistry and reaction mechanism changes; novel experiments evaluating deactivation effects on the reaction mechanism and performance; and development of models predicting deactivation effects.
