Abstract

The physico-chemical structure of co-pyrolysis char significantly affects its gasification reactivity. Pore distribution and microcrystal structure of co-pyrolysis char from polyvinyl chloride (PVC) and bituminous coal were investigated by specific surface area analyzer and X-ray diffraction. Based on fractal theory and deconvolution method, the influence of PVC on co-pyrolysis char structure was analyzed quantitatively. The results showed that the specific surface area of co-pyrolysis char increased slightly compared with PVC char. Similar to the PVC char, the pore size distribution of co-pyrolysis char was wide and uniform. The ordering of carbon microcrystal structure of co-pyrolysis char was promoted by the addition of PVC. This study can provide basic data for exploring the relationship between gasification characteristics and structure parameters of co-pyrolysis char.
