Abstract: A process for dewatering a thermochemical oil. The process comprises providing a thermochemical oil comprising water; adding a solvent selected from mesityl oxide, 2-methyltetrahydrofuran, dioxane and furfural to the thermochemical, oil, to form a mixture comprising the thermochemical oil and the solvent; heating the mixture to remove an azeotrope comprising water and the solvent from the mixture, thereby forming a dewatered thermochemical oil. A dewatered thermochemical oil. A fuel precursor.

Abstract: A process for obtaining an oil derivative. The process comprises the following steps: providing a thermochemical oil comprising a compound having a hydroxyl group, wherein the thermochemical oil is crude or refined oil resulting from thermochemical conversion of organic material; additionally providing a compound having an acyl group by feeding the compound having an acyl group, or a carboxylic acid or an ester as starting material for conversion to the compound having an acyl group, to the thermochemical oil; and reacting the compound having a hydroxyl group with the compound having an acyl group, thereby forming an ester between said compounds. A process for obtaining an intermediate composition, the process comprising blending the oil derivative with a refinery feedstock. An oil derivative or an intermediate composition. A process for obtaining a fuel component, the process comprising hydrotreating or hydrocracking the oil derivative or intermediate composition.
