Study of the co-pyrolysis behavior of sewage-sludge/rice-straw and the kinetics

摘要：

In order to study the co-pyrolysis characterisitics of sewage-sludge/rice-straw, pyrolysis experiments were carried out through a thermal analyzer. The pyrolysis processes were analyzed through the curves of TG and DTG. The results show that the co-pyrolosis behavior is not a simple summation calculation, but has obviouse synergistic effects. Rice straw significantly affects the release of volatile matter in the co-pyrolysis. It inhibits in the begining period, and promotes in the middle and later periods. With the increase of rice straws amount, the temperature range of the volatile matter release reduces, volatile matter release acceleratedly, both the speed and rate of weight loss increase. Kinetic analysis demonstrates that parameters in the stage of volatile matter liberation, which can be well linear fitted, have kinetic compensation effect in the process of co-pyrolysis.
