Abstract: The present invention relates to an aqueous coating composition system for the treatment of cellulosic articles, which includes a first aqueous composition having a pH of at least 10 and comprises potassium silicate and a penetration aiding agent, wherein the potassium silicate is present in a range of from 1.5 to 32% by weight, the molar ratio of silicon (Si) to potassium (K) of said potassium silicate is 1.2-2.1; and a second aqueous composition comprising an emulsion of at least one alkoxy silane and/or siloxane compound. The present invention further relates to a method for treating cellulosic articles and uses thereof.

Abstract: A biofuel product comprises a slurry of pulverized combustible solid biomass material in a combustible liquid product of vegetable origin. In accordance with the invention, the product of vegetable origin is glycerol, and a mixture ratio between the glycerol and the pulverized solid biomass material is such, that the slurry at least upon heating to around 90° C. has a low viscosity and is pumpable. The glycerol utilized is obtained as a byproduct in the production of biodiesel fuel or soap, fatty acids, fatty alcohols or alkyl esters, and the pulverized combustible solid biomass material preferably is lignin powder, and/or wood powder and/or other pulverized vegetable solid biomass material, such as peat, and/or powder of carbon from vegetable material. The biofuel product may be used as a replacement for heavy fuel oil, for example.
