Abstract
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.
