“…The transformation of methanol to propylene (MTP) has been 8 gaining extensive interests in view of the strong demand for 9 propylene in the petrochemical industry [1,2]. Currently, propyl-10 ene is mainly produced as a by-product of the conventional oil- 11 based processes, such as petroleum refining and naphtha steam 12…”

“…28 29 30 The olefins interconversion reaction (3) plays a critical role in 31 the production of propylene, since most of the higher olefins 32 (C 4 -C 7 ) in the effluent are recycled to the industrial reactor to 33 continue methylation reaction (2) and olefins interconversion 34 reaction (3). Methanol cracking reaction (1) is not so important in 35 the MTP process.…”

“…The intensity of the peak at 1225 cm −1 represents the presence of structure containing four chains of five‐rings. The band near at 450 and 550 cm −1 represents the SiO 4 , AlO 4 internal tetrahedron units and the five membered rings of the ZSM‐5 zeolite, respectively . FT‐IR in the range of 3000‐3800 characterizes the surface hydroxyl (OH − ) groups, further indicating the structure of HZSM‐5 is not destroyed after post‐treatments and infers the successful synthesis process in our experiments.…”

Hierarchically porous P substituted HZSM‐5 (H[P, Al]‐ZSM‐5‐AT‐0.05 M ) was successfully synthesized by isomorphous substitution method with introduced P atoms into ZSM‐5 zeolite frameworks followed by alkali treatment. H[P, Al]‐ZSM‐5‐AT‐0.05 M was characterized by XRD, ICP‐OES, SEM, FT‐IR, N2 adsorption‐desorption, NH3‐TPD, XPS, Py‐IR, and TG‐DTA, respectively. The surface area, pore volume, particle size and P/Al (molar ratio) are 328 m2.g−1, 0.23 cm3.g−1, 563 nm and 0.027, respectively. The catalytic performance of H[P, Al]‐ZSM‐5‐AT‐0.05 M in coupling reaction of methanol with 1‐butene was investigated in the fixed‐bed reactor. On the condition of reaction temperature at 500°C under atmosphere pressure, the main product is propylene with the selectivity and yield of 33.7% and 31.0%, respectively. Hydrogen transfer index was calculated to 0.24. Moreover, its diffusion limitation was investigated with the self‐etherification of benzyl alcohol reaction. The value of Thiele modulus (η ) and effectiveness factor (ϕ ) are 0.08 and 16.9, respectively.
