Abstract
An integrated process is provided for converting methanol, dimethylether or the like to heavy hydrocarbon products, especially distillate range hydrocarbons. In a first stage catalytic process oxygenate feedstock is converted to lower olefins. C.sub.3.sup.+ olefins are selectively sorbed in an interstage sorption fractionator and passed along with gasoline sorbent to a second stage oligomerization reactor. Distillate range hydrocarbons are useful as diesel fuel or the like.
