Measurement of Physical Properties of Cracking Catalysts: A Review of the Work of API Committee on Analytical Research


The Subcommittee on Measurement of Physical Properties of Cracking Catalysts, of the American Petroleum Institute Committee on Analytical Research, has been engaged for the past six years on a study of methods of measurement of physical properties. A progress report is now in the draft stage and will present recommended terminology, methods of measurement of density and pore volume, and tentative methods of measurement of particle size by sieving, liquid sedimentation, and air elutriation procedures. Studies are continuing on methods of measurement of surface area, refinement and correlation of particle size procedures, applicability of the various methods to fluid hydroforming catalysts, and measurement of hardness and attrition of pelleted catalysts.
