This patent describes a process for increasing the selectivity of conversion of oxygenates to aromatic hydrocarbons in the catalytic conversion of an organic, oxygenate feed to a hydrocarbon product by contacting the feed with a solid, porous catalyst having a Constraint Index of 1 to 12 and acidic functionality. The catalyst comprises a crystalline aluminosilicate zeolite having a silica:alumina ratio of at least 12, which has been treated to a temperature of at least 725/sup 0/C. in an essentially water-free atmosphere to reduce it acidity to an alpha value below 100.
