16 Claims

1. A process for production of a hydrocarbon fraction from an oxygenate feedstock, comprising the steps of

providing a process feed comprising an amount of an ammonia precursor, hydrogen and an amount of said oxygenate feedstock, at a temperature above 200° C., directing said process feed to contact a material catalytically active in hydrodeoxygenation (HDO) under hydrotreating conditions to provide a hydrodeoxygenated intermediate product,

wherein said ammonia precursor provides an amount of ammonia corresponding to a partial pressure of NH3 in the presence of said material catalytically active in hydrodeoxygenation being at least 1.0 mbar and less than 20 mbar.
