Bifunctional Catalysis in Alkanes Conversions
Bifunctional catalysts composed of metal particles and zeolite play an important role in the conversion of alkanes into their isomers or cracking product. The catalytic performance is mainly decided by the chemical state of metal particles, topology and acidity of zeolite, and also the spatial arrangements of two functional components. As an industrialized process, insights into the complicated interplay of adsorption, diffusion and kinetics on bifunctional catalysts are still needed for rational design of better catalysts.
Zeolites with one-dimensional micropores will be used in this research program. The spatial organization of metal particles with zeolite and alumina binder will be precisely controlled at nanoscale. Conversion of model hydrocarbon molecules will be conducted to acquire the diffusion and kinetics information during reaction. In addition, the studies on metal particle size, acid strength and density of zeolite will be included in this program. By means of advanced electron microscopy and spectroscopic techniques, we intend to obtain a clear framework that visualizes the interplay between catalyst nanostructure and catalytic performance.
