An integrated system is provided for converting methanol or the like to heavy hydrocarbon products, especially distillate range hydrocarbons. In a first stage catalytic process oxygenate feedstock is converted to lower olefins. Byproduct aromatics are passed through a second stage oligomerization reactor with olefins. Distillate range hydrocarbons are recovered and hydrotreated to provide an improved fuel product.
