The deep processing of lignocellulose feedstock (including waste from the woodworking industry, agriculture, and agro-industry) allowing the high-added value products to be obtained is one of the key scientific problems. Lignocellulose biomass is a potential feedstock for the production of heat, electricity, fuel, chemicals, and other bioderived products. The liquefaction is considered to be one of the most promising ways to convert lignocellulose biomass into liquid fuels. During the liquefaction, lignocellulose biomass can be efficiently converted into important base compounds, such as furfural, 5-hydroxymethylfurfural, levulinic acid and its esters, ?-pentylactone, alkyl glycosides, and phenols. The search of effective catalysts for liquefaction is the main task for the development of the technology for obtaining liquid fuels from biomass.
In this work, the liquefaction of the wood waste in the presence of a heterogeneous catalyst was studied. The novel Ni-containing catalyst supported on the natural carbonaceous material was used in this work. The influence of the reaction parameters on the biomass conversion, and product yield was estimated. The effect of the solvent, reaction temperature, hydrogen pressure, and preliminary treatment of biomass was analysed. It was shown that the developed catalyst allows the feedstock conversion to be about 90 wt. % for the non-hydrolysed sawdust. The preliminary hydrolysis of the feedstock increased the conversion up to 95 wt. %. The composition of the liquid products were presented by the products of the hydrolysis of cellulose, hemicelluloses, and lignin, as well as the polyols, 5-hydroxymethylfurfural, aromatics, and cyclic compounds.
