Abstract
Supercritical water gasification technology can realize the resource utilization of biomass waste. Formation and evolution of the pore structure of particles in supercritical water are different from that of the conventional state due to the unique physical properties of supercritical water. While pore structure affects the flow, heat transfer and chemical reaction of particles in supercritical water obviously, it is crucial to investigate the pore structure evolution. In this paper, biomass gasification experiment is carried out in the batch reactor first to obtain solid particles. Then the pore structure properties of the obtained solid particles are comprehensively characterized. The influence of different operating conditions on the formation and evolution of pore structure is obtained by analyzing the pore structure properties of the particles. It is found that the pore volume of biochar is about 57 times higher than that of raw material, and the specific surface area is enlarged about 86 times.
