Abstract: The invention relates to a method for producing an oil rich fraction (OF) from primary feedstock (FS) that comprises water, first salt, second salt, and biomass. The feedstock (FS) is provided to a first reaction zone (Z1) of a conversion reactor (100), where it is allowed to react at a temperature of at least 350° C. in a pressure of at least 160 bar to form converted primary feedstock. The method comprises separating from the converted primary feedstock a first salt rich fraction (SF1), a second salt rich fraction (SF2), and an oil rich fraction (OF). The method comprises withdrawing the oil rich fraction (OF) from the first reaction zone (Z1) and withdrawing the first salt rich fraction (SF1) and the second salt rich fraction (SF2) from the conversion reactor (100). In the method the first salt rich fraction (SF1) comprises at least some of the first salt dissolved in the water, the second salt rich fraction (SF2) comprises at least some of the second salt in solid form, and at least one of the first salt and the second salt is a salt capable of catalysing the reaction of the biomass of the primary feedstock (FS) with the water of the primary feedstock (FS) to produce the oil rich fraction (OF). A device for the same.

Abstract: A method for manufacturing biomass based fuel configured to reduce chemical and/or mechanical effects of flue gas on heat transfer surfaces is described. The method comprises providing biomass and steam into a reactor; maintaining said biomass and said steam simultaneously in the reactor, in a pressure of at least 10 bar(a) and at a temperature from 180° C. to 250° C. for at least 2 minutes; and decreasing the pressure in the reactor and/or conveying biomass out of the reactor such that the pressure of the environment of the biomass decreases below 5 bar(a), to produce steam-exploded biomass. The method further comprises adding some combustion additive to the biomass and/or the steam-exploded biomass.

Abstract: Biomass based fuel configured to reduce chemical and/or mechanical effects of flue gas on heat transfer surfaces. The biomass based fuel comprises steam-exploded biomass and some combustion additive. The combustion additive is selected from a group of additives that are capable of reducing chemical and/or mechanical effects of flue gas on heat transfer surfaces. The combustion additive may comprise fouling-reducing additive and/or an additive reducing corrosion potential. In addition, a method for manufacturing biomass based fuel configured to reduce chemical and/or mechanical effects of flue gas on heat transfer surfaces. The method comprises providing biomass and steam into a reactor; maintaining said biomass and said steam simultaneously in the reactor, in a pressure of at least 10 bar(a) and at a temperature from 180 ° C. to 250 ° C. for at least 2 minutes; and decreasing the pressure in the reactor and/or conveying biomass out of the reactor such that the pressure of the environment of the biomass decreases below 5 bar(a), to produce steam-exploded biomass. The method further comprises adding some combustion additive to the biomass and/or the steam-exploded biomass.
