Zeolite catalysts that could allow the efficient synthesis of n-butene, such as 1-butene, trans-2-butene, and cis-2-butene, in dimethyl ether (DME)-to-olefin (DTO) reaction were investigated using a fixed-bed flow reactor. The zeolites characterized by N2 adsorption desorption, X-ray diffraction (XRD), thermogravimetry (TG), NH3 temperature-programmed desorption (NH3-TPD). A screening ten avail...

Methanol to olefins (MTO) reaction as an important non-oil route produce light has been industrialized, and received over 80% ethylene plus propylene selectivity. However, achieve high single or selectivity towards the fluctuated market demand is still full of challenge. Small-pore SAPO-14 molecular sieve a rare MTO catalyst exhibiting extra-high It provides us valuable clue for further underst...
