Abstract:
Bio-oil is biomass-based pyrolysis product which is used as useful products and energy. The search of new upgrading processes for the enhancement of the yields and the quality of bio-oil is the key to improve the efficiency and reduce costs. Catalytic cracking upgrading is a process where deoxygenation occurs in presence of a catalyst at atmospheric pressure and hydrogen is not required. The aim of this study is to investigate the effects of using 5, 10 and 15% of bentonite and zeolite as catalysts on bio-oil to improve its properties. Raw and upgraded bio¬oil properties (pH, total acid number and water content) and its chemical components are tested to follow the process. Both catalysts achieve the same reduction of acidity in bio-oil: pH increasing of 0,7 and TAN decreasing of 7 mg KOH/ g bio-oil. Water content remains constant at 22%wt. A study of using the HZSM-5 over the time shows that the upgrading process takes place in 15 min and zeolite replacement permits a further improving of bio-oil properties to pH of 3,4.
