Effect of lignin on the co-pyrolysis of sludge and cellulose

ABSTRACT

In order to investigate the role of the lignin in the co-pyrolysis process of the sludge and the cellulose, the co-pyrolysis process was carried out in a thermogravimetry analyzer. The result shows that when the proportion of the sludge:cellulose:lignin was 1:1:0.4, the main co-pyrolysis temperature range was narrower, the ultimate pyrolysis weight loss was more, and the synergistic effect had a longer duration time. When the pyrolysis temperature was below 400°C, the addition of the lignin could promote the co-pyrolysis process of the cellulose and the sludge, such as the decrease of the activation energy E.
