The use of natural minerals as raw material for the manufacture of synthetic zeolite is <br /> <br /> <br /> <br /> <br /> still not widely practiced. Along with the development of technology, synthetic <br /> <br /> <br /> <br /> <br /> zeolites have been found more than 200 types of zeolite framework. Zeolite Y is a <br /> <br /> <br /> <br /> <br /> synthetic zeolite which has a biggest use in the petrochemical industry, especially as <br /> <br /> <br /> <br /> <br /> a catalyst in Fluid Catalytic Cracking (FCC). Perlite and fly-ash has been <br /> <br /> <br /> <br /> <br /> successfully applied to create zeolite-Y at low temperatures, but still in a mixture <br /> <br /> <br /> <br /> <br /> with Zeolite-A. This research will try to implement a similar composition of perlite <br /> <br /> <br /> <br /> <br /> and fly-ash with kaolin as a source of silica and alumina natural materials to <br /> <br /> <br /> <br /> <br /> synthesize zeolite-Y at low temperatures. Kaolin is used in this research due to its <br /> <br /> <br /> <br /> <br /> application as a source of silica and alumina has produced zeolite-Y with a fairly <br /> <br /> <br /> <br /> <br /> high purity, but still using the hydrothermal method. Kaolin is first activated by <br /> <br /> <br /> <br /> <br /> adding NaOH and calcined at a temperature of 650 C, producing metakaolin. <br /> <br /> <br /> <br /> <br /> Metakaolin with ludox, and water is used as raw material for the synthesis of zeolite- <br /> <br /> <br /> <br /> <br /> Y. Effect of NaOH and water mixture in the chemical composition of the synthesis <br /> <br /> <br /> <br /> <br /> results observed in this study. Two compositions of each metakaolin mixed with <br /> <br /> <br /> <br /> <br /> NaOH at three different compositions , and then heated at 90 oC for three and five <br /> <br /> <br /> <br /> <br /> days. The products formed is characterized by the X - Ray Diffraction (XRD). XRD <br /> <br /> <br /> <br /> <br /> results that have been done shows that the composition of the mixture with Si / Al <br /> <br /> <br /> <br /> <br /> similar to perlite, 8,89 SiO2 : Al2O3 : 31,51 Na2O : 549,23 H2O have typical peak <br /> <br /> <br /> <br /> <br /> pattern of zeolite-Y.
