Abstract
Catalysts and methods for large-scale production of the catalysts are described. An exemplary catalyst composition includes molybdenum, vanadium, tellurium, niobium, oxygen. In the catalyst composition, the molar ratio of molybdenum to vanadium is from 1:0.05 to 1:0.60, the molar ratio of molybdenum to tellurium is from 1:0.01 to 1:0.30, and the molar ratio of molybdenum to niobium is from 1:0.01 to 1:0.40. Oxygen is present at least in an amount to satisfy the valency of any present metal oxides, and the composition includes less than 1.0 wt. % of sulfur.
