Modulated Excitation DRIFTS and Steady-State Isotopic Transient Kinetic Analysis (SSITKA) of NH3-SCR-DeNOx on Cu-Containing Zeolite Y
Key Points
The research aims to explore the catalytic properties of Cu-modified zeolite Y in NH3-SCR-DeNOx reactions.
Utilized modulated excitation DRIFTS for excitation modulation analysis.
Employed steady-state isotopic transient kinetic analysis (SSITKA) to study reaction kinetics.
Analyzed commercial zeolite Y in Na+, H+, and NH4+ forms with specific n(Si)/n(Al) ratios.
Demonstrated that copper modifications enhance the catalytic performance of zeolite Y.
Observed notable changes in reaction kinetics depending on the ion forms present.
Identified optimal conditions for effective NH3-SCR-DeNOx operations.
Abstract
As-received (in the form of Na + , H + , NH4 + ) commercial zeolite Y with n(Si)/n(Al) ratio of about 2.6 modified with copper cations was investigated in...
