Abstract

The main objective of this project was to synthesize and aggregate larger Silicalite-1 crystals in one step that can eliminate the use of binders. A series of experiments was performed. First, the importance of silica in the synthesizing solution was investigated. Next, the time allowed for the bead to soak in the solution was increased. Then a different type of silica bead was tested. Lastly, the silica to structure directing agent ratio was decreased. The main findings of these experiments were: the presence of silica in the solution provided more evenly dispersed growth of crystals on the bead; the soaking time had little effect on the outcome of the synthesis; and an increase in structure directing agent led to more nucleation sites which covered the bead more uniformly with crystals.
