Abstract:
In this paper, thermogravimetric (TG) analysis was applied to study the effects of Na and Li-Na alkali silicates derived from coal fly ash on the catalytic pyrolysis of cellulose, lignin and pine wood chips at different temperatures ( 400, 500 and 600 °C). In presence of NaSiO3, LiNaSiO4 and Al2O3, the yield of volatile matter (VM), which includes the uncondensable gases and the condensable bio-oil products, was lower compared to the runs without catalyst. The maximum volatiles yield followed the order: No catalyst > Al2O3> LiNaSiO4 > NaSiO3. Oxygen was removed maily by decarboxylation and dehydration reactions, with decarboxylation preferential in presence of LiNaSiO4.
