Abstract: A process plant and a process for production of a hydrocarbon suitable for use as jet fuel from a feedstock being a renewable feedstock or an oxygenate feedstock, including combining the renewable feedstock with an amount of a hydrocracked intermediate product, directing it to contact a material catalytically active in hydrodeoxygenation under hydrodeoxygenation conditions to provide a hydrodeoxygenated intermediate product, fractionating the hydrodeoxygenated intermediate product in at least two fractions including a first fraction of which at least 90% boils below a defined boiling point and a second fraction of which at least 90% boils above the defined boiling point, directing at least an amount of the second fraction to contact a material catalytically active in hydrocracking under hydrocracking conditions to provide the hydrocracked intermediate product, the process being suited for efficiently converting the upper-boiling point of an oxygenate feedstock such as a renewable feedstocks to a lower boiling product.

Abstract: A process plant and a process for production of a hydrocarbon suitable for use as jet fuel from a feedstock being a renewable feedstock or an oxygenate feedstock, including combining the feedstock with an amount of a liquid diluent, directing it to contact a material catalytically active in hydrodeoxygenation under hydrotreating conditions to provide a hydrodeoxygenated intermediate product, separating the hydrodeoxygenated intermediate product in at least two fractions; a vapor fraction and a liquid fraction, directing at least an amount of the liquid fraction to contact a material catalytically active in isomerization under isomerization conditions to provide an isomerized intermediate product, directing at least an amount of the isomerized intermediate product and a stream comprising sulfur to provide a hydrocracked intermediate product, and fractionating the hydrocracked intermediate product to provide at least a hydrocarbon suitable for use as jet fuel.

Abstract: A process plant and a process for production of a hydrocarbon fraction suitable for use as jet fuel from an oxygenate feedstock, which may be a feedstock being a renewable feedstock, including combining the feedstock with a diluent hydrocarbon stream to form a hydrotreatment feed stream to contact a material catalytically active in hydrotreatment under hydrotreating conditions to provide a hydrotreated intermediate product, directing at least an amount of said hydrotreated intermediate product to contact a material catalytically active in hydrocracking under hydrocracking conditions to provide a hydrocracked intermediate product, separating the hydrocracked intermediate product in a hydrocracked intermediate liquid fraction and a gaseous fraction, directing at least an amount of said hydrocracked intermediate liquid fraction to contact a material catalytically active in hydrodearomatization under hydrodearomatization conditions to provide a treated product comprising the hydrocarbon fraction suitable for use as jet fuel.

Abstract: A process plant and a process for production of a hydrocarbon fraction suitable for use as jet fuel from a feedstock being a renewable feedstock or an oxygenate feedstock, including combining the feedstock with an amount of a hydrocracked intermediate product and optionally an additional liquid diluent, to form a combined feedstock, directing the combined feedstock to contact a material catalytically active in hydrodeoxygenation under hydrotreating conditions to provide a hydrodeoxygenated intermediate product, separating the hydrodeoxygenated intermediate product in at least two fractions; a vapor fraction and a liquid fraction, directing at least an amount of the liquid fraction to contact a material catalytically active in isomerization under isomerization conditions to provide an isomerized intermediate product, fractionating said isomerized intermediate product to provide at least a hydrocarbon suitable for use as jet fuel and a bottom fraction, hydrocracking the bottom fraction to provide the hydrocracked intermediate product.
