Abstract (en)
[origin: FR2844262A1] Acrylic acid production by two-stage catalytic reaction of propane and steam with continuous catalyst regeneration comprises using a catalyst comprising molybdenum, vanadium, tellurium or antimony, oxygen and at least one other element selected from niobium, tantalum, tungsten, titanium, aluminum, zirconium, chromium, manganese, iron, ruthenium, cobalt, rhodium, nickel, palladium, platinum, antimony, bismuth, boron, indium and cerium. Acrylic acid production by feeding an oxygen-free gas comprising propane and steam and optionally an inert gas into a first reactor containing a transported bed of catalyst, separating the gas from the catalyst, passing the catalyst to a regenerator, feeding the gas into a second reactor containing a transported bed of catalyst, separating the gas from the catalyst, recovering acrylic acid from the gas, passing the catalyst to a regenerator and recycling the regenerated catalyst to the first and second reactors comprises using a catalyst comprising molybdenum, vanadium, tellurium or antimony, oxygen and at least one other element selected from niobium, tantalum, tungsten, titanium, aluminum, zirconium, chromium, manganese, iron, ruthenium, cobalt, rhodium, nickel, palladium, platinum, antimony, bismuth, boron, indium and cerium.
