ABSTRACT:

Nanocrystalline ZSM-5 zeolite from ethylene diamine template have been prepared and characterized using XRD, TEM, TG/DTA, FT-IR, Nitrogen adsorption, XPS, MASNMR techniques and methanol to olefin reaction. Synthesis were carried out using a standard gel composition for 2,4 and 6th day. X-ray diffraction pattern of fourth day sample did not show any peaks, like 6th day sample. However its FT-IR spectra of framework region shows similarity with 6th day sample. TEM image of 4th day sample show the presence of nanoparticle which is lower than 10 nm size. 6th day samples are platelets of micron range. However 4th day sample properties are similar to 6th day samples. Its selectivity towards methanol to olefin conversion is higher than X-ray crystalline ZSM-5 samples.
