Abstract: The present disclosure relates to 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 oxygenates 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 0.1 mbar, This has the associated benefit that the ammonia precursor releases ammonia by thermal reaction, such that the presence of ammonia may limit the extent of formation of high boiling product in the hydrodeoxygenation process.
