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...
