Synthesis of nanosized ZSM-5 using different alumina sources

Alumina sources can influence different aspects of ZSM‐5 crystallization and it leads to change in the properties of the final product.

Description
Summary:Alumina sources can influence different aspects of ZSM‐5 crystallization and it leads to change in the properties of the final product. The crystallinity of nanosized ZSM‐5 zeolite from precursors mixtures containing different alumina sources, e.g. sodium aluminate, aluminum sulphate, aluminum hydroxide and alumina has been studied. The produced samples were investigated using XRD, SEM, FT‐ IR and BET surface area. The product obtained by sodium aluminate and aluminum sulphate was ZSM‐5 phase. Whereas, the product obtained by aluminum hydroxide and alumina was the albit phase. As‐synthesized ZSM‐5 was prepared by sodium aluminate, as alumina source was the highest crystallinity. It was found that the average crystallite size increased in the following order; alumina
