DOI: 10.1002/er.6113
Abstract: In this work, the structural function of char gasification is modelled theoretically. Considering that different components will have different pore characteristics after pyrolysis, char is divided into different micro‐structures according to its corresponding components, and… read more here.

DOI: 10.1016/j.fuproc.2017.12.019
Abstract: Abstract The purpose of this study is to investigate the evolution of O-containing structures of char during gasification. Mallee wood (4.75–5.60 mm) from Western Australia was gasified in a fluidised-bed reactor at 600–900 °C in O-containing (pure… read more here.
