Debris from olive-tree pruning represents a great volume of residual biomass in Spain, where annual production reaches 4.0 million tonnes, from which chemical, fuel and biological products can be developed. The economic feasibility of the process involves making use of the entire debris in its three main fractions: hemicellulose, cellulose and lignin. In this study we have studied the main factors that affect to the autohydrolysis process (temperature, time and acid concentration) as well as...
