Aromatisation of alkanes mechanism. In this issue of Chem Catalysis, Liu et al.



Aromatisation of alkanes mechanism. However, the yield of aromatics is always limited by the simultaneous… Abstract The catalytic aromatization of n -alkanes is an important process in the chemical industry, especially for the production of value-added aromatics from the abundant and unreactive small alkanes. deepens the under-standing of the coupling reaction of light alkanes with CO and provides a new route for light alkane aromatization. Dec 19, 2010 · The stoichiometry of n- alkane aromatization requires the loss of four equivalents of H 2. explore the aromatization mechanism of coupling reaction of light alkanes with CO, in which methyl-substituted cyclopentenones are considered important intermediates for realizing high selectivity of aromatics over H-ZSM-5. While the confusions and the doubts as to whether the conversion of alkanes to aromatics on platinum alumina catalysts follow the classical bifunctional mechanism, involving both metal and acid sites ranges on, more work must be done Nov 18, 2021 · Converting light alkanes to aromatics is highly desired but challenging. The reaction mechanism of aromatization of C 6 + alkanes and the effects of the dispersion of metal sites, electronic state, and acidity, morphology and pore structure of the support on the catalytic performance are discussed in detail. Feb 1, 2022 · The aromatization mechanism of short-chain alkanes is considered to be a really complicated reaction network, involving dehydrogenation, pyrolysis, oligomerization, hydrogen transfer, cyclization, isomerization, aromatization and condensation, which haven't been fully figured out so far. There are controversial opinions regarding the exact mechanism of aromatization of alkanes (Ako and Susu, 1986). Aug 19, 1992 · Mechanism of formation of the primary products of alkane aromatization As found by other authors the primary products of light alkane transformation at high temperature on H-ZSM-5 result from their scission into alkene+hydrogen or +alkane with one exception however: ethane leads to methane, whose formation requires hydrogen.
