Synergistic co-conversion of pentane and methanol to aromatics over bifunctional metal/ZSM-5 zeolite catalysts

Zeolite ZSM‐5 synthesized from natural silica sources and its applications: a critical review

“…5,6 Most known zeolite materials have several noticeable features, such as high surface area (200-900 m 2 g −1 ), tailorable porous structures, [7][8][9] sieving properties, 4,[10][11][12][13][14][15] useful adsorption and ion-exchange properties, and Lewis acids/bases. 8,[16][17][18][19][20][21][22] Therefore, zeolites can have extensive applications in petroleum refining, [23][24][25][26] gas purification, [27][28][29][30] wastewater treatment, [31][32][33][34][35][36][37][38] seawater desalination, [39][40][41][42] soil amendment, [43][44][45] etc. Among synthetic zeolite materials, Zeolit Socony Mobil Number 5 (ZSM-5) has attracted widespread attention due to its unique channel structures (e.g., mobil five (MFI) type, high-silica pentasil with opening capacity of around 5.1 to 5.6 Å) and special properties (e.g., high selectivity, hydrophobic nature, high acid strength, and thermal stability).…”

Roles of ethanol in coke formation and HZSM-5 deactivation during n-heptane catalytic cracking

“…11 It was found that coupled methanol and hydrocarbon cracking was beneficial to light olefin production, and the reaction mechanism was discussed in detail. 12,13 Kazemi et al 14 found that the addition of C4–C6 hydrocarbons into methanol promoted light olefins selectivity over HZSM-5 zeolites at 470–490 °C. Cordero-Lanzac et al 15 and Chang et al 16,17 found that methanol addition promoted n -pentane and n -hexane conversion over HZSM-5 zeolites.…”

Production of aromatics from butanol over Ga-promoted HZSM5 catalysts: tuning of benzene–toluene–xylene and ethylbenzene (BTEX) selectivity

“…7 The light hydrocarbons (methane, ethane, propane, butane, pentane, hexane, heptane and octane) aromatization route has also been studied extensively as an alternate route to produce building block aromatics to meet the growing demand for BTX and regulate the consumption of petroleum resources. [14][15][16][17][18] However, increasing global warming, climate change, and depletion of fossil fuels reserve on consumption of fossil fuels are the motivational factors for the exploration of renewable energy resources to produce these building block chemicals and fuels. Among the various renewable sources available on earth, biomass solely can be used as a feedstock for the production of various organic chemicals and fuels.…”
