Synthesis and performance of H-SAPO34 catalyst for conversion of methanol to light olefins

Light olefins are basic raw materials for petrochemical industries and the global demand for the latter is growing. In the present study, conversion of methanol to light olefins in presence of acidic SAPO-34 molecular sieve as the reaction catalyst has been investigated. SAPO-34 was synthesized by hydrothermal method, applying morpholine as the template. The molecular sieve was then changed into protonated form by ion exchange process with ammonium chloride at 80oC. A fluidized bed reactor was applied to investigate performance of catalyst. It was found that the methanol conversion and olefin selectivity were 29.91% and 55.14% respectively.
