Abstract

The influence of starch on the pyrolysis was studied from macro and micro angles. In this paper, briquette pyrolysis was operated with thermal analyzer. The experimental data showed that with the increase of starch content, the reaction rate was increased and the activation energy was decreased. The calorific value was improved in the briquette with starch. The starch does not change the oxygen-containing functional groups of the briquette, just increased the number of hydroxyl. And the specific surface area was increased, but the pore volume and the average pore size were decreased of briquette compared with the coal though the micropore morphology analysis.
