Abstract: A composition includes bitumen; optionally vegetable oil or derivative thereof; and a lignin preparation, where the lignin preparation has a lignin purity of 60-100 wt. % with respect to the weight of the lignin preparation; and a lignin average molecular weight of 1000-5000 g/mol. The composition may be an asphalt binder composition or asphalt composition. A method of paving or roofing includes use of this composition. Further, a method of preparing an asphalt composition, includes mixing bitumen with filler material, adding lignin preparation and vegetable oil to the mixture obtained. The lignin preparation and the vegetable oil may be added simultaneously.

Abstract: A catalytic method is disclosed for the valorization of lignin. The method comprises subjecting lignin to a catalyzed hydrothermal conversion reaction, said reaction being conducted in the presence of water at an alkaline pH>8 and a temperature of 200° C.-300° C., under the influence of a noble metal catalyst comprising a carbon support. The same reaction can also be applied to subsequently defunctionalize one or more phenolic compounds, notably guaiacol, so as to produce six-membered cyclic hydrocarbons, such as phenol.

Abstract: The invention relates to a lignocellulose preservative composition comprising in the range of from 50 to 98 wt % of a pyrolysis oil obtainable by pyrolysis of lignocellulosic material, a polymerisable furan compound and a catalyst for polymerising the furan compound in a catalytically effective amount. The invention further relates to a process for producing preserved lignocellulosic material comprising impregnating lignocellulosic material by immersion in such composition and subsequently curing the impregnated material and to preserved lignocellulosic material obtainable by such process and to an engineered wood or non-wood product comprising such lignocellulosic material.
