Olefins are the key hydrocarbons having a crucial role in petrochemical industry. Limitation in the natural resources combined with the increase in the oil prices led researchers to find alternative ways to synthesize these crucial monomers from a cheaper, non-oil based and a more sustainable resource. Methanol, having a biodiesel-based production route, seeks attention in the last decade to be used as olefin source. The reaction from which olefins are produced using methanol is called “Methanol to Olefins” (MTO). MTO provides a chance to produce light olefins independent from petroleum based sources. In this study, HZSM-5 zeolite was used as catalyst in MTO reaction. The activity tests were conducted at 300, 400, 450, 500 and 550°C for 4 hours using a fixed-bed reactor. Methanol conversions of HZSM-5 were in between 74 - 97% whereas total light olefins selectivities were changing from 31% to 51% with changing temperature. Temperature scanning experiments showed that the optimum temperature for MTO was 450°C with the highest methanol conversion of 97% and total light olefin selectivity of 51%. Moreover, propane and isobutane formation slightly increased with increasing temperature from 300 to 550°C while methanol in product stream was decreasing, especially at elevated temperatures like 550°C.
