LOWER ALKANE OXIDATIVE DEHYDROGENATION CATALYSTS AND A PROCESS FOR PRODUCING OLEFINS

摘要

A catalyst of formula (1): Mn alpha E<1>  beta E<2>  gamma Ox wherein E<1> is at least one element selected from P, As, Sb, B, S, Se, Te, F, Cl, Br, I, Nb, Ta, W, Re and Cu; E<2> is at least one element selected from Cr, Fe, Co, Ni, Ag, Au, Zn, Tl, Sn, Pb, Bi, Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Y, La, Ce, Nd and Sm; alpha = 1, beta = 0.01-10, gamma = 0-5, and x is a numerical value determined by the oxidation states of the elements other than oxygen.
