PROCESS FOR SYNTHESIZING NAX ZEOLITE MATERIAL FROM UNCLEAN RICE HUSK ASH

Abstract

This paper describes the synthesis process of zeoJit NaX material from unburned rice husk ash, including the following steps: (i) Step 1: Create a NaSiOi solution by heating rice husk ash in sodium hydroxide solution to create the NaSiOi precursor; (ii) Step 2: Create a sodium aluminate solution by dissolving aluminum powder in sodium hydroxide solution; (iii) Step 3: Create an intermediate mixture by mixing the NaSiOi solution from step (i) with the NaSi aluminate solution from step (ii) in the reaction vessel; (iv) Step 4: Create an aluminosilicate gel by vigorously stirring the intermediate mixture obtained from step (ii) for 2 hours at 50°C; and (v) Step 5: Heat the aluminosilicate gel mixture from step (iv) to 90°C and maintain for 4 hours; The solid residue was filtered, centrifuged, and dried at 100°C until no change in weight was obtained to obtain NaX zeolite material in powder form.
