摘要：
Conversion of methanol-to-hydro carbons has been studied over beta-zeolites with varying contents of aluminum, obtained by dealumination of the parent sample with oxalic acid. It was found that the dealumination leads to catalysts which are more resistant to deactivation. The total amount of methanol which might be converted to hydrocarbons before the catalyst becomes completely deactivated increased. The conversion capacity is higher at high reactant feed rates.
