ABSTRACT:
An integrated process 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, which are passed through a second stage oligomerization reactor. A reactor sequencing technique is useful for multi-stage catalytic conversion systems employing a number of fixed bed catalytic reactors at various process temperatures and catalytic activity levels.
