WebDec 26, 2024 · Abstract. A systematic study of the comparative performances of 4% Ga-, 4% Zr-, and 1% Cr-impregnated H-ZSM-5 catalysts for oxidative dehydrogenation of propane in the presence and absence of CO 2 is presented. It was found that methane, ethene, propene, butene, pentene, and BTX are the major products from all of these catalysts at various … WebReaction Network The reversible reaction for propane dehydrogenation to propylene on supported platinum catalyst is given by: Propane Dehydrogenation: C 3 H 8 ⇄ C 3 H 6 + H …
Mechanism and Kinetics of Propane Dehydrogenation and Cracking …
WebMar 15, 2012 · Propane cracking reaction is a competitive reaction with dehydrogenation reaction over Brønsted acid sites. Different from the dehydrogenation reaction, the cracking reaction involves the cleavage of C–C bond rather than the cleavage of C–H bond [53]. Scheme 1 c depicts the reaction route of the cracking reaction. In steam cracking, a gaseous or liquid hydrocarbon feed like naphtha, LPG or ethane is diluted with steam and briefly heated in a furnace without the presence of oxygen. Typically, the reaction temperature is very high, at around 850 °C, but the reaction is only allowed to take place very briefly.

WebJan 22, 2024 · Under propane-CO 2 ODH reaction conditions, V 2 O 5 is irreversibly reduced to V 2 O 3, which leads to a progressive shift from propane ODH to the propane cracking reaction. The participation of CO 2 in the ODH reaction is negligible and the reaction pathway is governed by the availability of lattice oxygen in V 2 O 5 and V 2 O 4 .
