Claims4
In a low temperature process for converting ethane to ethylene by catalytically oxydehydrogenating ethane exothermically at a temperature of from about 150.degree. C. to about 450.degree. C. in the gas phase, the improvement comprises using a calcined catalyst containing
- Mo.sub.a V.sub.b Nb.sub.c Sb.sub.d X.sub.e
- in the form of oxides
- wherein:
- X=at least one of the following:
- Li, Sc, Na, Be, Mg, Ca, Sr, Ba, Ti, Zr, Hf, Y, Ta, Cr, Fe, Co, Ni, Ce, La, Zn, Cd, Hg, Al, Tl, Pb, As, Bi, Te, U, and W;
- and
- a=0.5 to 0.9
- b=0.1 to 0.4
- c=0.001 to 0.2
- d=0.001 to 0.1
- e=0.001 to 1.0.
