NOVELTY - Preparing (M1) diesel fuel product (147) involves: contacting feedstock (105) of biocomponent feed with hydrotreating catalyst (120) in several hydrotreating stages with continuous gas phase environment; mixing feedstock, prior to/during contact with additional hydrotreating stage, with recycled product stream (157); mixing effluent from several hydrotreating stages with second recycled product stream; separating effluent and contacting liquid phase effluent portion with catalyst in hydroprocessing stage (140) with continuous liquid phase environment under hydroprocessing conditions.    USE - For preparation of a diesel fuel product (claimed).    ADVANTAGE - The hydroprocessing zone can be operated under effective catalytic dewaxing conditions. The method eliminates need to circulate hydrogen gas or a separate hydrogen phase through the catalyst; does into includes diluent for dissolving hydrogen in the feed. The method for producing a diesel fuel from a feedstock that is at least partially biocomponent in origin; can provide reduced hydrogen consumption during hydrotreatment of the feed; can operate at hydrogen treat gas rates near the overall hydrogen consumption rate, which can avoid the need to recycle hydrogen, thus reducing or eliminating the need to remove CO and/or CO2 from gas phase effluent produced by the reaction; can allow for integration into a single reactor of a dewaxing or aromatic saturation stage while reducing or minimizing any poisoning of the dewaxing or aromatic saturation catalyst; includes multiple catalyst beds or stages, optionally within a single reactor, which can be operated so that the beds are in a continuous gas phase environment. This is the typical situation e.g. in a trickle bed reactor. Thus it can be preferred for the reactor to be operated so that at least the final bed/stage is in a continuous liquid phase environment, e.g. which can be accomplished by exhausting excess gas from the reactor prior to the final bed.    DETAILED DESCRIPTION - Preparation (M1) of a diesel fuel product (147) involves: contacting a feedstock (105) with a hydrotreating catalyst (120) in several hydrotreating stages under effective hydrotreating conditions, where each hydrotreating stage has continuous gas phase environment, at least a portion of the feedstock comprises biocomponent feed, the feedstock has oxygen content of at least 1 wt.% and sulfur content of at least 500 wppm, and has a first stoichiometric hydrogen need for the hydrotreating; mixing the feedstock, prior to or during contact with at least one additional hydrotreating stage, with a recycled product stream (157) into which hydrogen is at least partially dissolved, where the additional hydrotreating stage is downstream from at least one of the several hydrotreating stages; mixing the effluent from several hydrotreating stages with a second recycled product stream into which hydrogen is at least partially dissolved; separating the effluent from several hydrotreating stages into a gas phase effluent portion and liquid phase effluent portion; and contacting the liquid phase effluent portion with a catalyst in a hydroprocessing stage (140) having a continuous liquid phase environment under effective hydroprocessing conditions to form a diesel fuel product, where the liquid phase effluent portion has a second stoichiometric hydrogen need for the hydroprocessing stage, and where the diesel fuel product is deoxygenated and has a sulfur content of less than or equal to 100 wppm, where the total treat gas rate of hydrogen relative to the feed is less than or equal to 1.2 times the combined first and second stoichiometric hydrogen needs, and where the total hydrogen treat gas rate is less than or equal to 750 scf/bbl (130 Nm3/m3). An INDPEPENDENT CLAIM is included for preparing (M2) diesel fuel product involving: introducing a feedstock into a reactor, where the reactor includes at least one hydrotreating stage in a continuous gas phase environment and a dewaxing stage in a continuous liquid phase environment, at least a portion of the feedstock comprises of a biocomponent feed, and the feedstock has an oxygen content of at least 1 wt.% and has cloud point; contacting the feedstock with hydrotreating catalyst in at least one hydrotreating stage under effective hydrotreating conditions, where the feedstock has a first stoichiometric hydrogen need for the hydrotreating stages; mixing the feedstock, prior to or during contact with hydrotreating catalyst in at least one hydrotreating stage, with a recycled product stream into which hydrogen is or becomes at least partially dissolved; mixing the feedstock, prior to contact with dewaxing catalyst in the dewaxing stage, with a second recycled product stream into which hydrogen is or becomes at least partially dissolved; exhausting from the reactor a gas phase effluent portion of a hydrotreated effluent from the hydrotreating stages; and contacting a liquid phase effluent portion of the hydrotreated effluent with dewaxing catalyst in the dewaxing stage under effective dewaxing conditions to form a diesel fuel product, where the liquid phase effluent portion have a second stoichiometric hydrogen need for the dewaxing stage, where the diesel fuel product being deoxygenated and has a cloud point at least 10 degrees C below the cloud point of the feedstock.
