Previously, we observed a transformation of zeolite X and Y to ZSM3 [24] which was suggested to be in line with the work of Hong-Jian et al[25] who produced ZSM2 from NaX seeds. Recently, Goel et al [26] discussed the inter-zeolite transformations route without organic structure-directing agents for zeolite synthesis.
Dec 31, 2018· Introducing clay as starting materials for zeolite synthesis could lead to about 5 times cheaper zeolites based on the average prices from major global suppliers of chemicals [12, 14, 16]. Ethanol is a fuel that does not meet the criteria of modern engine and is rather commonly used as a blending oxygenate agent to gasoline [9].

The synthesis of Faujasite Zeolite from Locally available Erusu Kaolin clay sourced in Nigeria has been attempted using standard procedures which have proven sufficient upon slight modifications and reported in literature. The zeolite was characterized with Scanning …
In this study, the effect of crystallization time on the synthesis of zeolite Y from Elefun kaolinite clay was investigated. During the synthesis of zeolite Y, the raw Elefun kaolinite clay was beneficiated thoroughly with water for 7 days before it was calcined at a 850oC for 6 hours to thermally convert it to metakaolin.
The beneficiation was to remove most of the impurities (quartz, pebbles, plants remain and grits) from the clay. Figure 1; Zeolite A synthesis from Kankara kaolin process flow diagram. Mixing/stirring heating @85 0c for 2mins Washing/filtering using suction pump Synthesis @85 oC -2hrs in
