Gamma alumina is widely used in industry for applications in catalysis, due to its high mechanical strength, high surface area, and good porosity levels. These catalytic supports have, however, complex porous structures, with porous organizations ranging from the nanometre to the millimetre scale. These properties have a significant impact on the mass transfer kinetics in the catalyst, and hence on the performance of the catalytic process. In gas diffusion-limited pellets, the optimization of the structure is vital in enabling IFPEN (industrial sponsor), and industry in general to reduce their emissions and achieve their greenhouse gas emission targets in the future.
