1. A process for production of a hydrocarbon fraction suitable for use as jet fuel from an oxygenate feedstock, comprising the steps of
a. combining the feedstock with an amount of a hydrocracked intermediate product and optionally a liquid diluent to form a combined feedstock, directing said combined feedstock to contact a material catalytically active in hydrodeoxygenation under hydrotreating conditions to provide a hydrodeoxygenated intermediate product,
b. separating said hydrodeoxygenated intermediate product in at least two fractions including a vapor fraction and a liquid fraction,
c. optionally providing an amount of said liquid fraction as said liquid diluent, directing at least an amount of said liquid fraction to contact a material catalytically active in isomerization under isomerization conditions to provide an isomerized intermediate product,
d. fractionating said isomerized intermediate product to provide at least a hydrocarbon suitable for use as jet fuel and a bottom fraction,
directing at least an amount of said bottom fraction to contact a material catalytically active in hydrocracking under hydrocracking conditions to provide the hydrocracked intermediate product.
