The purpose of this project was to develop the methods for studying surface properties of alkyltrichlorosilanes modified zeolites. Alkyltrichlorosilane modified zeolites show promising catalytic ability and can survive under severe conditions. Surface energies of modified zeolites need to be studied to understand the macroscopic behaviors of zeolites during the reaction and the product separation processes. Glass slide surface was used as smooth, non-porous model. Silica beads were used as non-smooth, non-porous model. ZSM5, HY, and Beta zeolites were used in this study. Contact angles were measured with goniometer. Five pure solvents were used in this study. Water-organic systems were used to develop the study method. Surface energy was calculated with Owens and Wendt's approach.
