A method for filtering a non aqueous liquid such as a biodiesel to reduce the levels of sterol glucosides and/or saturated monoglycerides.

A protectant and sealant solution and method of use thereof, configured to protect wood from premature decay when disposed in contact with the earth. The solution is composed of processed hemp oil which is mixed with bio-diesel and other oils to form the protectant solution. The wood is then impregnated with the solution via pressure treatment within a retort cylinder. The solution is configured to protect utility poles and other wooden construction members which are known for prolonged contact with soil. The solution is designed as a safe replacement for pentachlorophenol solutions which have been found to be harmful to the soil and water table.

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.
