The Optimization of Production Zeolite Synthesis Y From Rice Husk Ash

Abstract

Rice husk is the milling byproduct of rice and is a major waste product of the agriculture industry. Amorphous silica, commonly referred to as rice husk ash, was extracted from rice husk by acid leaching, pyrolysis, and carbon-removing processes. On the other hand, the pure silica with a high specific surface area, high melting point and high porosity can be obtained from rice husks. These properties make the ash a valuable raw material for many industries. This paper is study of synthesized of zeolite Y from rice husk ash. Zeolite Y synthesis is used for petroleum industry as expensive catalyst. Rice husk was calcined at temperature 700oC for two hours using furnace to produce pure silica . The composition of synthesized of zeolite Y from rice husk was 2.24 Na2O : Al2O3 : 8 SiO2 : 112 H2O. The gel solution was mixed at room temperature for 24 hours using autoclave. Then, the gel solution was heated with variable temperature and time crystallization. The product zeolite synthesis Y was filtered and washed with distilled water until pH lower than ten, than dried at oven. This product was analyzed with X-Ray Diffraction (XRD). From XRD analyze result indicated that from rice husk ash can produced zeolite synthesis Y which high structure and crystallization degree. The optimum condition for synthesized zeolite Y from rice husk ash was temperature 100oC for 48 hours.
