Abstract:
In this work, which is encompassed inside the European project LIFE BIOREFFORMED, an innovative strategy to produce renewable value-added chemicals is developed, using a semi-industrial pyrolysis plant to produce bio-oil, biochar and gas from wood coming from forest management. Different types of lignocellulosic biomass were used (Stone pine, Aleppo pine, Oak, Strawberry tree, Heather, Cork oak and Chestnut tree) and compared to produce bioproducts like acids, sugars and antioxidants, among others. Different pyrolysis operation temperatures were studied (300, 400 and 500 ºC) to determine the best conditions for the obtention of the desired products. It was observed that there were not significant differences regarding the obtention of bioproducts between different biomass species, even though some of them were softwoods and other hardwoods. Heather, oak and the two pine species exhibited especially good results in the production of acids and sugars (e.g. 25,6 g of acids/kg of biomass were obtained with heather). Regarding the production of phenolics, pine species showed the highest yields of the different biomasses with approximate values of 4 g/kg of biomass.
