Abstract

In the conversion of methanol, the effect of acide property of heteropoly compounds on the catalytic activity was investigated. The pretreatment of Cu-exchanged 12-tungstophosphoric acid with hydrogen enhanced both the selectivity for propane and the conversion of methanol, and the pretreatment of Al-exchanged 12-tungstophosphoric acid with water enhanced the acid strength of the catalyst. The water added into the reactant decreased the conversion of methanol, while the pretreatment temperature did not affect it but the propylene/propane ratio. Various partially-substituted Al salts of 12-tungstophosphoric acid showed different catalytic activities depending on the degree of Al-substitution.
