O-03　バイオブタジエン合成を念頭に置いたジメチルエーテルからn-ブテン合成触媒開発

抄録

In the dimethyl ether (DME)-to-olefin (DTO) reaction, zeolite catalysts that could allow the efficient synthesis of n-butene, such as 1-butene, trans-2-butene, and cis-2-butene, were investigated using a fixed-bed reactor. A screening of ten available zeolites indicated that the ferrierite zeolite with NH₄⁺ as a cation type showed the highest n-butene yield. The effect of the temperature of calcination as a pretreatment method on the catalytic performance was studied using three zeolites with promising topologies. The ferrierite zeolite showed the highest n-butene yield at a calcination temperature of 500°C.
