文摘

The performance of catalysts for ODH reactions depends on metal species composition. Partial substitution of Ni with Fe or Co improves Ni-Bi-O/Al2O3 catalytic effect. Partial Fe substitution up to 50% improves butadiene selectivity. Partial Co substitution up to 50% improves n-butane conversion. Partial substitution of Ni with Fe and Co improves both activity and selectivity. Partial substitution of Fe and Co changes the catalyst acidic/basic character.
