Production of butene and butadiene by oxidative dehydrogenation of butane over carbon nanomaterial catalysts

3-D Multi-Tubular Reactor Model Development for the Oxidative Dehydrogenation of Butene to 1,3-Butadiene

“…Although there are several commercial catalytic dehydrogenation processes including Catofin and UOP Oleflex [10], a few problems that inhibit the commercialization of the direct dehydrogenation have been found. First of all, the process is highly endothermic, so the reaction occurs at a relatively high temperature (e.g., 500 to 650 • C) [9,11]. Furthermore, such severe reaction conditions cause side reactions such as thermal cracking and rapid coke formation on the catalysts, which leads to catalyst deactivation [12].…”

“…Furthermore, such severe reaction conditions cause side reactions such as thermal cracking and rapid coke formation on the catalysts, which leads to catalyst deactivation [12]. To overcome such limitations, oxidative dehydrogenation (ODH) of n-butene has been proposed and has been widely studied in recent years [9][10][11]. ODH is an exothermic reaction at relatively low temperature (e.g., 300 to 400 • C), which takes place in the presence of oxygen on the surface of catalysts, producing C4 olefin.…”

“…V/MgO composites and Cr 2 O 3 /Al 2 O 3 catalysts are also used [14,15]. Conversely, Park et al [11] suggested the use of metal-free carbon nanomaterials as potential catalysts due to their environmental benignity and unique surface characteristics. In particular, ferrite and Bi-Mo catalysts have been extensively used due to their high catalytic activity and selectivity [7,16].…”
