报告内容摘要:
Biomass is typically widely dispersed, bulky, of high moisture content and low-energy-density, leading to its high logistic cost. It is also of a fibrous nature and has a poor grindability, dictating that a biomass-based bioenergy plant must be flexible to take large biomass particles as feedstock. Additionally, biomass conversion is dominantly gaseous phase reactions during combustion/gasification as results of its high moisture and volatile contents. This causes problems of mismatch in fuel properties between biomass and coal when biomass is co-processed with coal in coal-based plants. Pyrolysis is a flexible thermochemical technology that converts biomass into solid (biochar), liquid (bio-oil) and pyrolytic gas that can be used to supply the energy for pyrolyser operations. Biochar and bio-oil are high-energy-desnity fuels favourable for transport. Instead of consuming substantial energy to achieve size reduction of biomass particles, the biochar can be easily ground into fine char particles due to its excellent grindability. Biochar fines can then be suspended into bio-oil to make bioslurry fuels which are of high energy density suitable for transport. Our systematic study on bioslurry fuels production from the pyrolysis of mallee biomass in Western Australia demonstrates that bioslurry fuels have small energy and carbon footprint, low production costs, desired fuel properties which meet all specifications for stationary applications (e.g. co-firing with coal in coal-fired power stations and combustion in stationary engines etc). The deployment of bioslurry fuels from biomass pyrolysis enables a favourable concept based on a combination of many distributed small-scale pyrolyers to produce bioslurry fuels locally in areas where biomass is available and centralised stationary applications of bioslurry fuels which are produced and transported from many of these distributed pyrolysers.
报告人简介:
Prof. Hongwei Wu received his BE and ME in Thermal Power Engineering from Huazhong University of Science and Technology in Wuhan, China in 1993 and 1996, respectively. He then moved to Australia and completed his PhD study in the Department of Chemical Engineering from the University of Newcastle in early 2000. After worked at Monash University as a postdoctoral research fellow for over 2 years, he was then appointed as a faculty member (lecturer) in the Department of Chemical Engineering at Curtin University in Perth, Western Australia in August 2002 and has been a staff member in the department since then. He is currently a full professor in the Department and also the Deputy Director of Fuels and Energy Technology Institute at Curtin University. He leads a research team of 15 members, focusing on R&D on the thermochemical processing of solid fuels including coal, biomass, solid wastes etc. He was appointed as a member of the editorial advisory board of the American Chemical Society journal – Energy & Fuels in 2007 and subsequently appointed as the Associated Editor of the journal in April 2008.
