Factorial design methods and analysis of variance have been applied to the experimental determination of adsorption equilibrium constants. A factorial design with three levels of temperature (110°, 130° and 150°C), three particle diameters (0.3, 0.9 and 1.5 cm) and two different impregnation loadings led to the identification of significant effects and interactions for the calculation of the equilibrium constants. This methodology requires no assumptions and identifies the principal experimental variables, and their interactions, which have the greatest effect on the adsorption.
