SINTESIS ZSM-5 DARI ABU TERBANG BATUBARA PLTU PT. BUKIT ASAM (PERSERO), TBK DENGAN VARIASI WAKTU KRISTALISASI DAN RASIO SiO2/Al2O3

Synthesis ZSM-5 From Fly Ash Of PLTU PT. Bukit Asam (Persero), Tbk With Variation Of Crystalitation Time and SiO2/Al2O3 Ratio (Bunga Nurmawati Situmorang, 2014, 40 pages, 8 tables, 32 pictures, 4 enclosure Indonesia has abundance coal. Coal is used by industry as fuel. Coal burning was producted waste such as fly ash and bottom ash coal. Fly ash coal contained the high silicate and alumminate. The research about fly ash coal have a good prospect to converted become zeolite synthetic such as ZSM-5. It has incresed usage in industry, either as cation exchanger, absorber, or catalyst. The synthetic zeolite more liked then natural one because they have better stability along with better activity and selectivity. ZSM-5 (Zeolite Socony Moil-5) is a type of synthetic zeolite that used in various industry processes. The research learned to converted become zeolite ZSM-5 and to know effect of SiO2/Al2O3 ratio of synthesis of ZSM- 5. Zeolite synthesis was conducted using hydrothermal method with time synthesis crystallisation varied at (18, 24, 30 hour) and comparison of SiO2/Al2O3 mole ratio (30, 35, 40, 45, 50) were used at constant temperature 200oC. The results of XRD analysis showed that at mole ratio of SiO2/Al2O3 (50) for 30 hour, zeolite ZSM-5 was produced at crystalination grade of 78%.
