catalytic composition for selective oxidation of ethane and / or ethylene to acetic acid, its use, and process for the production of acetic acid from a gas mixture.

摘要

A catalyst composition for the selective oxidation of ethane and/or ethylene to acetic acid which composition comprises in combination with oxygen the elements: MOa.Wb.Agc.Ird.Xe.Yf (I) wherein X is the elements Nb and V; Y is one or more elements selected from the group consisting of: Cr, Mn, Ta, Ti, B, Al, Ga, In, Pt, Zn, Cd, Bi, Ce, Co, Rh, Cu, Au, Fe, Ru, Os, K, Rb, Cs, Mg, Ca, Sr, Ba, Zr, Hf, Ni, P, Pb, Sb, Si, Sn, Tl, U, Re and Pd; a, b, c, d, e and f represent the gram atom ratios of the elements such that 0a=1, 0=b=1 and a+b=1; 0(c+d)=0.1; 0e=2; and 0=f=2. The catalyst composition may be used in the production of acetic acid and in an integrated process for the production of acetic acid and/or vinyl acetate.
