Abstract
The invention concerns a method for producing acrylic acid from propane in the absence of molecular oxygen. Said method is characterized in that it consists in passing a gas mixture free of molecular oxygen and comprising propane, water vapour, as well as, optionally, an inert gas, over a catalyst including molybdenum, vanadium, tellurium, oxygen and at least another element X selected among niobium, tantalum, tungsten, titanium, aluminium, zirconium, chromium, manganese, iron, ruthenium, cobalt, rhodium, nickel, palladium, platinum, antimony, bismuth, boron, indium and cerium, and on a co-catalyst of formula (II): MoBiFeCoNiKSbTiSiCaNbTePbWCu. The invention also concerns a solid catalytic composition comprising said catalyst and co-catalyst and the use of said composition for producing acrylic acid from propane.
