Summary:

In this work, high stable mesoporous γ-aluminas with different pore structure were synthesized. New kinds of templates were adapted to prepare alumina based catalysts with uniform and bimodal mesopore distribution with ‘small’ and ‘large’ mesopores. Preliminary catalytic tests showed high catalytic activity of synthesized samples in methanol dehydration reaction and selectivity to dimethyl ether (alternative motor fuel) comparing to conventional catalysts.
