Effect of Pre-Biotreatment on the Liquefaction Process of Sawdust (SD)

The conversion of biomass to useful liquids needs sever conditions of temperature and pressure. The present study aims to reduce pyrolysis temperature and pressure to lower limits, so as to reduce cost of the process. To achieve this goal, bio treatment step of biomass before pyrolysis was adopted. Special types of fungi were used that are well known of its activity on producing cellulase enzyme. The biomass, was treated with fungus, and incubated for various durations. Then the bio treated samples were pyrolyzed in order to get liquid products. The study show that bio treatment was successful to provide higher liquids yield compared with untreated raw materials.
