Provided is a method for upgrading a bio-based material, the method including the steps of pre-treating bio-renewable oil(s) and/or fat(s) to provide a bio-based fresh feed material, hydrotreating the bio-based fresh feed material, followed by separation, to provide a bio-propane composition.

Aqueous wastewater from hydrothermal liquefaction (HTL) systems is typically high in chemical oxygen demand (COD), which renders classic aerobic wastewater treatment to be prohibitively expensive. HTL wastewater can be processed using thermochemical wet oxidation in a manner that is not only cost efficient but also contributes more heat than is required for the energetically demanding HTL process. Provided are methods and devices for integrated hydrothermal liquefaction of biomass and treatment of resulting wastewater.

The present invention relates to a method of subjecting a biomass feedstock to hydropyrolysis, the method at least comprising the steps of: a) supplying a biomass feedstock and a fluidizing gas comprising hydrogen to a bulk reactor zone of a fluidized bed reactor containing a deoxygenating catalyst; b) subjecting the biomass feedstock in the bulk reactor zone of the fluidized bed reactor to a hydropyrolysis reaction by contacting the biomass feedstock with the deoxygenating catalyst in the presence of the fluidizing gas, thereby obtaining a hydropyrolysis reactor output comprising at least one non-condensable gas, a partially deoxygenated hydropyrolysis product and char; wherein the bulk reactor zone is cooled by means of a cooling fluid flowing through a plurality of tubes running through the bulk reactor zone, the plurality of tubes having inlets into and outlets from the bulk reactor zone; and wherein the cooling fluid flowing in the tubes at the point (‘A’) where the biomass feedstock enters the bulk reactor zone has a temperature of at least 320° C., preferably at least 340° C., more preferably at least 350° C., even more preferably at least 370° C., yet even more preferably at least 380° C.

The substantially gas stream is sent directly from the final stage reactor and separator to further downstream processing.

The present invention relates to a process for the conversion of a feedstock comprising at least 50 wt % related to the total weight of the feedstock of triglycerides, fatty acid esters and/or fatty acids having at least 10 carbon atoms into hydrogen, olefins, dienes, aromatics, gasoline, diesel fuel, jet fuel, naphtha and liquefied petroleum gas comprising: a) introducing of said feedstock in a first reactor to produce linear paraffins in presence of a hydrodesulfurization catalyst and hydrogen, b) separating the effluent of said first reactor in at least three parts to produce at least a first stream comprising part of said linear paraffins and at least a second stream comprising part of said linear paraffins, and at least a third stream comprising part of said linear paraffins c) sending said first stream to a steam cracker to produce hydrogen, olefins, dienes, aromatics and gasoline, diesel fuel being further fractionated; d) introducing said second stream into a second reactor in presence of a hydrocracking or hydroisomerization catalyst to produce a mixture comprising diesel fuel, jet fuel, naphtha and liquefied petroleum gas being further fractionated e) blending said third stream with the diesel fuel obtained at said step d)
wherein said feedstock of said first reactor is diluted in order to limit the temperature increase within said first reactor; and wherein before entering the first reactor said dilution is performed with a weight ratio diluent:feedstock being 1:1, and wherein said diluent comprises at least part of said paraffins obtained at step b).
