ABSTRACT: Hierarchical zeolite has multilevel porosity to enable accurate and unhindered diffusion of reactant and product in the zeolite framework. It is an advanced material used to correct the constraint encountered in the conventional zeolite with a micropore system. The development of hierarchical zeolites involves using a mesopore-creating agent to create maximum porosity. This method usually deposits hazards to the environment and requires very high energy to remove them after their synthesis procedure. The additive-free synthesis of hierarchical zeolite is an advanced move to correct the synthesis of hierarchical zeolite Y. The report is on additive-free hierarchical zeolite Y from Aloji kaolin. The synthesized hierarchical zeolite Y has a surface area of 489.09 m2/g, a pore size of 5.76 nm and can be applied in chemical engineering processes.
