摘要: Abstract Mesoporous ZSM5 (mZSM5) was prepared by the dual templating method for n-heptane cracking and CO methanation. The properties of mZSM5 were tailored varying aging time in 0.5–3-day range. physical catalysts characterized with XRD, FESEM, nitrogen physisorption IR. XRD FESEM analyses indicated that mZSM5s possessed a high crystalline structure coffin-type morphology. Nitrogen analysis revealed presence both micropores mesopores surface area inter- intra-particle porosity. pyridine pyrrole adsorbed IR spectroscopy results demonstrated have intrinsic acidic basic sites, which are suitable acid and/or base catalyzed reactions. bare mZSM5-0.5D exhibited highest rate conversion (0.0230 μmol/m2 s) (0.0226 μmol/m2 s) at 573 K 723 K, respectively. performed good stability no deactivation up to 30 h Co-existence micro-mesopores acidic–basic sites is vital acid-catalyzed base-catalyzed
