Oxidative Dehydrogenation of Propane using a Manganese Molybdate

Abstract

A manganese molybdate (MnMoO4) was synthesized, characterized and used in the oxidative dehydrogenation of propane. It was found that the crystalline structure is the same before and after the reaction. The reaction was carried out in the 400-600 o C temperature range, with a space velocity between 50 and 150 ml/g.min. Propane conversion of 29,4%, with 25% selectivity to propene, was observed when the reaction was conducted at a space velocity of 150 ml/g.min and temperature of 600 ºC. Reaction products were the corresponding unsaturated hydrocarbons, CO, and CO2. Only a small part of the propane was cracked to ethylene and methane.
