讲座内容:

        Green gas (such as biohydrogen and biomethane) has the potential to qualify as an Ultra-Low Emission transport fuel. However, the optimal system to produce sustainable transport biofuel has yet to be defined. Biogas can be produced through anaerobic digestion and upgraded to biomethane. The conventional anaerobic digestion may suffer from two drawbacks: (1) Vulnerable to many environmental factors; and (2) Digestate generated after digestion still has a great amount of unutilised energy. A combined system including the concepts of cascading bioenergy and circular bioeconomy have been proposed, which includes four modular systems: (1) Feedstocksoptimisation and pretreatment; (2) Enhanced anaerobic digestion through addition of conductive materials; (3) Upgrading of biogas to biomethane through Power to Gas; (4) Pyrochar production through controlled pyrolysis of solid anaerobic digestate. The advantages of such system include: (1) Improved biomethane yield and production rate, allowing for higher organic loading rate; and (2) Enhanced total energy recovery through integration of solid digestate pyrolysis. The preliminary results demonstrated that as compared to conventional anaerobic digestion, the integrated system enhanced biomethane yield by 25%, peak biomethane production rate by 20%, and reduced lag-phase time by 48%. 

主讲人简介:

        Dr. Richen Lin is a Research Fellow in University College Cork, Ireland. He has been recently awarded the European Commission Marie Curie Individual Fellowship (2018). He received his PhD degree from Zhejiang University in 2016, and awarded as the Outstanding Graduate of Zhejiang Province. He serves as the reviewer for several journals in bioenergy area such as Renewable & Sustainable Energy Reviews, Applied Energy and Bioresource Technology. His research interests focus on microbial production of gaseous fuel from a wide range of organic wastes. In particular, he looks at (1) Lignocellulosic/algal biomass pretreatment, characterization, and kinetic modelling; (2) Fermentation and anaerobic digestion for hydrogen and methane production, and (3) Thermodynamics of microbial interspecies electron transfer in anaerobic digestion. He has published over 30 papers with more than 600 citations in peer-reviewed journals, such as Chemical Engineering Journal (Impact Factor 6.74, Elsevier) and Bioresource Technology (Impact Factor 5.81, Elsevier).
