“…The yield for the olefins on four catalyst samples decrease versus the reaction time and the occurrence of catalyst deactivation trend is H[P, Al]‐ZSM‐5 < H[P, Al]‐ZSM‐5‐AT‐0.05 M < HZSM‐5 < H[P, Al]‐ZSM‐5‐HT‐0.1 M. Although the H[P, Al]‐ZSM‐5‐AT‐0.05 M displays the slightly lower yield of olefins compared to H[P, Al]‐ZSM‐5, its catalytic stability is higher than other three catalyst samples. P/E (propylene/ethene) ratio can be used to indicate the presence of mesopores in the catalyst . As shown in Figure S3 (b), the lower value of P/E ratio was obtained on H[P, Al]‐ZSM‐5‐AT‐0.05 M. The probable reason is that the mesopores or cavities are located in the inner pores on catalyst.…”

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.

“…Brønsted acid sites are more likely to participate in the fast pyrolysis of biomass due to the nature of the various intermediate reactions involved. These acid sites have been previously shown to be active for the conversion of methanol to olefins and for gasoline transformations [161][162][163][164]; hydrocracking/cracking of naphtha [165,166], isomerization [167,168], polymerization [169,170], alkylation [106,171], aromatization [172,173] and other reactions involving C-O and C-C bonds cleavages. All of these reactions have been observed to occur during pyrolytic biomass-upgrades [174].…”

“…ZSM-5 catalyst is a vital part in the MTHC reaction because of its strong acidity for carbon-carbon scission, high surface area, and well-defined pore structure (Jin et al, 2009;Liu et al, 2010;Li et al, 2015;Mohammadparast et al, 2015;Rostamizadeh and Taeb, 2016). Its shape selectivity facilitates the conversion of fossil and biomass resources to heavier hydrocarbons, mainly aromatic compounds.…”

Precise product distribution data is very important for kinetic modeling of chemical reactions and chemical reactor design. In this work, H-ZSM-5 catalyst was hydrothermally synthesized and characterization tests including XRD, XRF, BET, and NH 3 -TPD revealed its physicochemical properties. Then, methanol conversion into hydrocarbons over ZSM-5 was investigated with WHSV of 4 h −1 at reaction temperature 410°C. Product distribution result indicated that C 3 -C 5 + and C 2 = -C 4 = were the major products in gaseous phase, and in liquid phase xylenes, three methyl benzene and C 10 + aromatics were the main components. It was also observed that the synthesized ZSM-5 had good performance in the methanol to hydrocarbons process and gave rise to highest activity (100%) during 10 h of operation approximately.
