Definitions
- Patent Application EP 608838 describes the preparation of an unsaturated carboxylic acid from an alkane by a catalytic vapor phase oxidation reaction in a co-fed fixed bed reactor, in the presence of a catalyst containing a metal oxide.
- the essential components are: Mo, V, Te, O, and at least one element selected from the group consisting of Nb, Ta, W, Ti, Al, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ni, Pd, Pt, Sb, Bi, Bo, In and Ce, these elements being present in precise proportions.
- Japanese patent application JP 2000-256257 describes the conversion of propane to acrylic acid in redox mode on a MoVSbNb catalyst. It is clearly indicated that the presence of water vapor is preferable to have a better yield of acrylic acid. Thus a water / propane molar ratio of greater than 0.5 is desirable.
- patent application US 2004/0138500 has been described a partial oxidation process of propane to acrylic acid in the presence of a multine metal oxide catalyst, and using a starting gas mixture consisting of propane, molecular oxygen and at least a diluent gas which comprises water vapor.
- EP 1238960 has been described a process for preparing acrylic acid from propane, in which a gaseous mixture free of molecular oxygen and comprising propane, water vapor, and optionally an inert gas, on a structure of solid composition Mo i VaT ⁇ b Nb c If d Ox to oxidize the propane according to the redox reaction:
- the process is greatly improved in terms of saving the amount of energy for the vaporization of water, and subsequently the amount of energy for its removal of the products of the reaction.
- the process is improved because acrylic acid is more easily separated from an effluent when the latter is as concentrated as possible.
- This effluent containing in addition acrylic acid, unconverted reagents, water vapor produced by the reaction and also all by-products of reaction, including by-products whose formation is favored by the presence of water (as especially propionic acid or acetone which are formed by hydration of the propylene intermediate of the reaction).
- the process is improved by a lesser formation of certain by-products of reaction.
- the present invention consists in the selective oxidation of propane to acrylic acid, in a circulating fluidized bed or in a fluidized bed, in the presence of a catalyst of structure:
- X is tellurium or antimony
- Z is niobium or tantalum
