Miss Dingding Yao, from Huazhong University of Science and Technology, is visiting the University of Leeds. She will stay in Leeds between November 2016 and November 2017. She worked on the hydrogen production from co-gasification of waste biomass and plastics under the supervision of Dr Paul T. Williams. Carbon deposited on the surface of catalyst during the experiment was also investigated. Dingding carried out experiments using a two stage fixed bed reactor, and was trained to use several analytical equipments including thermogravimetric analyser, gas chromatography, transmission electron microscope, scanning electron microscope and so on. Her work in Leeds also contributes to her PhD thesis, and strengthens collaboration between Huazhong University and University of Leeds.
