Patent ID: 7820867

Claim:
Process for converting oxygenate compounds to hydrocarbons comprising the steps (a) introducing a feed stream of synthesis gas to a synthesis section for the production of easily convertible oxygenates, (b) passing an effluent stream from said synthesis section containing easily convertible oxygenates to a gasoline synthesis section, (c) passing the effluent of said gasoline synthesis section to a separator and withdrawing from said separator hydrocarbons boiling in the gasoline boiling range, (d) admixing a recycle stream from the separator containing unconverted synthesis gas and volatile hydrocarbons with the feed stream of synthesis gas of step (a), (e) introducing a feed containing difficultly convertible oxygenates to the synthesis section of step (a) wherein the easily convertible oxygenates include compounds selected from the group consisting of methanol, ethanol, dimethyl ether, acetone, propanol, diethyl ether, ibutanol, propionaldehyde or mixtures thereof, and wherein the feed containing difficultly convertible oxygenates includes compounds selected from the group consisting of formaldehyde, acetaldehyde, hydroxyaldehyde, glyoxal, acetol, acetic acid, MeOAc, EtOAc, furfural, furfuryl alcohol, phenol, anisol, catechol, guajacol, creosol, cresolol, eugenol, naphtol or mixtures thereof.
