Scientific Essay from the year 2015 in the subject Chemistry - Other, , language: English, abstract: The present study investigates the oxidative de-hydrogenation of propane-butane (C3-C4) fraction over mono (Cr, Mo) and bi-metal (Cr-Mo) loaded MCM-41catalysts. The catalysts were prepared by sequential impregnation method at 500oC calcination temperature. Experiments were performed by feeding C3-C4 fraction and CO2 into a continuous flow quartz reactor at atmospheric pressure (P = 1 atm.), reaction temperatures between 500 - 650oC, gas hourly space velocity within 100 - 400 h-1, and at reaction time (tr) = 2h. The physicochemical properties and performance of catalysts were evaluated by BET, XRD, H2-TPR, and NH3-TPD characterization techniques. The major products are ethylene, propylene, isobutylene, butylene. This paper reports that the total yield of olefins (? C2-C4) = 71.6 % was achieved at 89.5 % conversion level of C3-C4 at 630oC. The results indicate that the addition of Mo to Cr/MCM-41 modifies its catalytic activity. The Cr/MCM-41 and Mo/MCM-41 catalysts were prepared for comparison purposes.

Ayodeji A. Ijagbuji was born on the 1st of September, 1984 in Ondo State, Nigeria. He attended the Staff Secondary School, Federal University of Technology, Akure, between 1994 to 2000. In 2006, he received the B.Sc. degree in Industrial Chemistry with a 2nd Class (Hons.) Upper (C.G.P.A = 4.3/5), and as the best graduating student from the Adekunle Ajasin University. Between 2007 to 2008, he rendered the voluntary National service at the Elf Petroleum Nigeria Limited, River State. In 2008, he became recognized as a Database 10g Administrator by Oracle, California, USA. He received a Russian language Diploma in 2010, the M.Sc. (with Distinction) in 2011, and Ph.D. degrees in 2015 in Chemical Technology of Inorganic Materials from the East Ukrainian National University, Luhansk, Ukraine. Between 2011 to 2015, he worked as a Research Assistant under the supervisions of Prof. Dr. Ivan I. Zakharov and Prof. Alexandre D. Tyulpinov. He is currently a lecturer in the Department of Chemistry and Industrial Chemistry, Adekunle Ajasin University. His research interests include Advanced oxidation process, Industrial-inorganic chemistry, and Quantum chemistry. He is a member of the American Chemical Society. He is the author of 3 thesis/dissertation, 1 book, and has co-authored in 1 book chapter, 2 patents, 5 journal articles, and 5 conference papers.
