    Abstract: A process and system for reducing contaminants contained in a contaminated feedstock comprising mixing the contaminated feedstock with water and at least one of metal scavengers or reactants, to form a feedstock-water-reactant mixture, feeding the mixture under pressure into a hydrothermal purification reactor, wherein the mixture is subject to heat, pressure, and turbulent flow conditions to cause rapid reaction of the inorganic contaminants with the metal scavengers or reactants to form inorganic salts that partition into an aqueous phase and maintaining the temperature, pressure, and turbulent flow conditions of the feedstock-water-reactant mixture for a predetermined space time to prevent the organic portion of the feedstock in the mixture from undergoing a conversion reaction and to form a hydrothermal reactor effluent; and separating the effluent into the aqueous phase containing salts of the inorganic contaminants and an organic phase that contains a lower concentration of inorganic contaminants than the contaminated feedstock.

    Abstract: The invention provides for a fluid having a boiling point in the range of from 100 to 400° C. and comprising more than 95% isoparaffins and containing less than 100 ppm aromatics, obtainable by the process comprising the step of catalytically hydrogenating a feed comprising more than 95% by weight of a hydrodeoxygenated isomerized hydrocarbon biomass feedstock, at a temperature from 80 to 180° C. and at a pressure from 50 to 160 bars. The invention also provides for a fluid having a boiling point in the range of from 100 to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% isoparaffins and less than 3% of naphthens by weight and having a ratio of isoparaffins to n-paraffins of at least 12:1, a biodegradability at 28 days of at least 60%, as measured according to the OECD 306 standard, a biocarbon content of at least 95% by weight, and containing less than 100 ppm aromatics by weight. The invention finally provides for uses of the fluid.
