Dr. Chunfei Wu from the University of Hull has visited Hebei University of Technology between 01/01/2017 and 10/01/2017 and Southeast University (29/12/2016-31/12/2016). A TGA analytical equipment and a in-situ DRIFTS reactor were tested in the Hebei University of Technology. The in-situ DRIFTS reactor can be used for mechanism studies of pyrolysis process. The reactor can be heated up to 1200 °C under various gas environment e.g. N2 and H2. Functional groups on the surface of feedstock or catalyst can be monitored during thermo-chemical conversion process.
