The authors describe ZSM-5 zeolite synthesized from the Na-TPA cation system for the first time using silica from rice husk ash. In this study, rice husk ash was the only source of silica and alumina used in the synthesis. The molar ratio of SiO/sub 2//Al/sub 2/O/sub 3/ in the husk was 24.88, which was constant throughout. The synthesis has been carried out for temperatures ranging from 125 to 200{sup 0}C and durations of synthesis has from 6 to 120 h with Na/sub 2/O/Al/sub 2/O/sub 3/ and H/sub 2/O/Al/sub 2/O/sub 3/ molar ratios ranging from 3.25 to 15.15 and 1081 to 2786, respectively. The effects of varying the composition of initial mixture, the alkalinity, and the time on synthesis were studied. The product at each stage has been characterized by using X-ray diffraction analysis, infrared spectroscopy, differential scanning calorimetry, and electron microscopy.
