    Abstract: The acidity of a zeolite catalyst is reduced by calcination in an essentially water-free atmosphere at temperatures above 700.degree. C., preferably from 725.degree. to 800.degree. C., to reduce the alpha value to less than 10 percent of its original value. The low acidity catalysts produced in this way may be used for conversions requiring low acidity, shape selective catalysis, including conversion of oxygenates to hydrocarbons. The calcined, low acidity catalysts exhibit improved selectivity to certain desired products.
