초록

DME has received much attention because of its possible use as a fuel and a chemical feedstock. Chemical conversion of DME to olefin (DTO) over various SAPO-34 catalysts was carried out using a fixed bed reactor. Main products of the reaction were light olefins such as ethylene, propylene and butenes. The best reaction conditions for high life time of the catalyst and high selectivity of light olefins were a reaction temperature of $400^{\circ}C$ and a WHSV of $3.54h^{-1}$. In addition, it was found that the deactivation of a SAPO-34 catalyst can be significantly suppressed by the addition of $ZrO_2$ as a supporter.
