Abstract: A process for producing a C3 olefin product stream and a hydrocarbon stream comprising hydrocarbons boiling in the jet fuel range, the process comprising: passing a feedstock stream comprising oxygenates over a catalyst active in the conversion of oxygenates for producing a first olefin stream; conducting the first olefin stream to a first separation step and withdrawing thereof a liquid hydrocarbon fraction comprising at least 50 wt % of the C3-olefins contained in the first olefin stream; conducting the liquid hydrocarbon fraction to a fractionation step and separating therefrom said C3 olefin product stream and the olefin product stream; and converting the olefin product stream into the hydrocarbon stream comprising hydrocarbons boiling in the jet fuel range, particularly sustainable aviation fuel (SAF), by subsequent oligomerization and hydrogenation. The invention provides also a plant for conducting the process.

Abstract: A process and plant for producing hydrocarbons boiling in the jet fuel range, comprising the steps: optionally passing a feedstock stream comprising oxygenates over a catalyst thereby forming an olefin stream; passing the olefin stream trough a combined oligomerization and hydrogenation step thereby producing a hydrocarbon stream comprising said hydrocarbons boiling in the jet fuel range.
