The invention relates to a porous formable material and to a method for producing it. Lignocellulose-based starting material in used in the method by forming a lignin- containing mixture from fractions obtained from biomass fractionation, which mixture is treated to form a porous object. In the method the material is foamed, formed, heat treated, carbonized and activated. The obtained carbonized and activated object is suitable to be used among other as a filler, filter and catalyst substrate. |
