methanol conversion to light olefins (mto) in the presence of synthesized nano sapo-34 and feapso-34 zeolites

New method of synthesizing pure sapo-34 and feapso-34 zeolites via aluminium chloride is presented in the presence of aluminium chloride as al source# the synthesized samples were characterized using xrd, ftir, and fesem analysis# xrd patterns showed diethyl amine (dea) template lead to production sapo-34 phase, also, feapso-34 catalyst showed higher crystallinity and larger crystallite size than sapo-34# the fesem results indicated that the morphology of the nanostructured catalysts is similar to the chabazite phase# catalytic performance of prepared zeolites for methanol to light olefins were evaluated on a fixed-bed reactor# catalytic performance tests of synthesized sapo-34 toward methanol to light olefins conversion showed higher ethylene / propylene ratio of feapso-34# the resulting catalytic tests showed a remarkable improvement in activity and stability of feapso-34 catalyst at 350 °c#
