Optimization Process of H-Zeolite Catalyst Preparation with Surface Response Methods

Abstract

H-zeolite have been produced from natural zeolites by chemical and physical activation process. The producing process has been optimized by the response surface method with variables process: X1 is a dimensionless number value for the concentration of NH4Cl solvent, and X2 is a dimensionless number value for the diameter of natural zeolite. The resphonse in this experiment is a surface area and pore diameter that analyzed by Brunauer, Emmet dan Teller. Regression analysis was obtained determination coefficient R2 0.84425. The optimization process produces a saddle-shaped contour with the critical value at the saddle area is -1.0759 for X1 and 0.8159 for X2.
