Ammoxidn. catalysts were regenerated by addn. of Bi and Mo. The catalysts were used in manuf. of acrylonitrile from propene. In an example, a regenerating soln. was prepd. from MoO3, H3PO4, NHO3, Bi(NO3)35H2O, and H2O. It was used to regenerate a SiO2-supported ammoxidn. catalyst contg. Bi, P, Mo, K, Co, Ni, and O.
