Particle Size Analysis of Catalysts
7 Dec 2012This application note from Malvern Instruments discusses the criticality of particle size in the development and production of heterogeneous catalyst materials, and presents data to demonstrate the utility of the Mastersizer 3000 particle size analyzer in achieving optimum reactivity. In addition to calculating a specific surface area, a unique feature this technique is the ability to predict attrition rate in a fluidized bed using dry powder measurements at different pressures.

Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
