A New Method for the Synthesis of Cr-V@MOF5 Catalyst Regarding the Investigation of the Simultaneous Effect of Effective Parameters in the Oxidative Dehydrogenation of Propane [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering
This research study utilized the synthesis method of the Cr-V@MOF5 catalyst to integrate findings from multiple prior studies. The oxidative dehydrogenation method was chosen due to its exothermic nature and lack of thermodynamic constraints on catalytic

Microwave-assisted direct synthesis of butene from high-selectivity methane [PDF]

open access: yesRoyal Society Open Science, 2017
Methane was directly converted to butene liquid fuel by microwave-induced non-oxidative catalytic dehydrogenation under 0.1–0.2 MPa. The results show that, under microwave heating in a two-stage fixed-bed reactor, in which nickel powder and NiOx–MoOy ...

Propane Oxidative Dehydrogenation on Vanadium-Based Catalysts under Oxygen-Free Atmospheres

open access: yesCatalysts, 2020
Catalytic propane oxidative dehydrogenation (PODH) in the absence of gas phase oxygen is a promising approach for propylene manufacturing. PODH can overcome the issues of over-oxidation, which lower propylene selectivity. PODH has a reduced environmental
