Book excerpt: Transition metal promoters of sulfated zirconia increase its catalytic activity for the conversion of n-butane. The promoter effects vary from one transition metal to another in the family zinc, iron, nickel, cobalt, and manganese. The most active catalyst so far tested is promoted by both iron and manganese. This catalyst is two or more orders of magnitude more active than unpromoted sulfated zirconia. The manganese promoter alone markedly increases the catalytic activity, but the activity declines very rapidly with time on stream in the flow reactor. Under the same experimental conditions, iron has a smaller but longer-lasting effect as a promoter than manganese, and to a first approximation, the iron- and manganese-promoted catalyst shows a behavior that is a superposition of those of the two individual promoters.
