Haochen Sun

I completed my PhD in 2024 from Institute of Coal Chemistry, university of Chinese Academy of Sciences (China). The topic of my thesis was a novel chemical looping process (CLPH) which can get inherently separated syngas. I mainly focused on the high-value utilization of biomass, chemical looping technology and waste management. I joined Bio and Circular Economy research group (Tampere University) as a post-doctoral researcher in September 2024. The goal of my current research is to develop a cost-effective OC which have a better tar elimination activities during biomass chemical looping gasification process and help to realize the whole process management of sewage sludge.

Expertise in catalyst synthesis, reactivity performance characterization (TPR, TPO), fixed-bed examination, XRD, etc.
