Abstract: This development is related to a supplementary cementitious material (SCM) comprising previously calcined clay that has poor or moderately poor kaolinite content (with contents of kaolinite below 60%) and a chemical activator which, depending on the quality of the clay, is selected from a silicate, a strong base or a mixture of activators comprising a mixture of silicate-strong base.

Abstract: The present disclosure refers to a process of obtaining a biocrude from biomass, where said process comprises the solvothermal liquefaction of the biomass in the presence of a mixture of solvents, until obtaining a gaseous phase, a solid phase, an aqueous liquid phase and an organic liquid phase comprising the biocrude. Wherein the mixture of solvents comprises between 0.5% w/w to 99.5% w/w of water and at least one solvent; and wherein the solvent is selected from alcohols, ketones, aldehydes, or precursors thereof under the processing conditions. The process described herein allows the use of biomass for the production of renewable fuels, as well as obtaining a biocrude with a yield greater than or equal to 30%, with a calorific value between 20 and 35 MJ/Kg and with a sulfur percentage lower than 1% w/w.
