    Abstract: In a broad aspect the present disclosure relates to a process plant and a process for upgrading a hydrocarbon mixture, withdrawn as a direct stream from a crude distillation unit and an initial boiling point below 200° C., and a fraction of at least 5% boiling above 500° C., 550° C. or 650° C. comprising the steps of a. directing said hydrocarbon mixture to a vacuum flasher unit, b. withdrawing a heavy hydrocarbon fraction from said vacuum flasher unit, c. withdrawing a light hydrocarbon mixture for hydrocracking from said vacuum flasher unit, d. directing said light hydrocarbon mixture for hydrocracking and a stream rich in hydrogen to con-tact a material catalytically active in hydrocracking, e. withdrawing a hydrocracked stream of hydrocarbon from said hydrocracker. with the associated benefit of limiting the amount of asphaltenes, metals and other heavy components contacting said material catalytically active in hydrocracking.

    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.
