Zeolite is an interesting crystalline porous material that has high surface area, high thermal stability and catalytically active acid sites. Zeolite is mostly used in the petrochemical industry as a catalyst, where it is utilized in the form of a composite with binders and shaped into different forms. The accessibility to the active sites of zeolite is usually hindered because of the binding material. This thesis explores the use of carbon nanostructures (CNS) as a binding material for zeolite. The high surface area, good thermal stability and flexibility of the CNS, as well as, its nanofibrous structure make it promising binding material for zeolite (micro and nano) particles. Furthermore, Nano zeolite particles were fabricated through the ball milling technique. The process of ball milling of H-Y zeolite tends to decrease its crystallinity and surface area. It was found that the addition of CNS during the ball milling process reduces the harsh destruction of zeolite particles and preserves its crystallinity and surface area. Lastly, the conversion of n-hexadecane cracking over the fabricated catalysts of ball milled H-Y zeolite were evaluated. Various parameters as catalyst stability, activity, catalyst selectivity, coking speed and attrition of the catalyst were assessed. Ball milled H-Y zeolite nano particles shows interesting catalytic activity and less coke formation compare to parent H-Y zeolite particles.
