Abstract
A catalyst composition for use in manufacturing methacrolein by reacting with one of isobutene and t-butanol, the catalyst composition being represented by the formula of: x (MoBiFeCoABO)/y Z. MoBiFeCoABOis an oxide compound. Z is a catalyst carrier is one of graphite, boron, silicon, germanium powder, and a mixture thereof. Mo, Bi, Fe, Co, and O are chemical symbols of molybdenum, bismuth, iron, cobalt, and oxygen respectively. A is one of W, V, Ti, Zr, Nb, Ni, and Re. B is one of K, Rb, Cs, Sr, and Ba. The catalyst is adapted to not only enhance the production of methacrolein with high activeness and high selectivity but also effectively control the heat point of the catalyst during the methacrolein manufacturing process to prolong the catalyst life.
