Dr. Naoko Ellis, Professor of Chemical and Biological Engineering at the University of British Columbia, Vancouver, Canada, is the Senior Research Director of the CMC’s Carbon Capture and Conversion Institute (CCCI), which is a collaborative partnership between CMC Research Institutes, the University of British Columbia and BC Research Inc. to evaluate and develop technical and economic options for carbon conversion and carbon capture. The CCCI works with researchers and technology developers from government, academia and industry to accelerate innovation from the lab bench to commercial scale use. Her expertise lies in the area of multiphase reaction engineering with emphasis on fluidized beds. Some current projects include: biomass gasification and pyrolysis; CO2 capture, including chemical looping combustion; pyrolysis product utilization; and biofuels.


Gasification of biomass allows production of syngas from which various chemicals and fuel are produced. However, biomass tar must be removed prior to downstream processing. Reducing the tar content in the syngas from biomass gasification remains one of the main challenges in the commercialization of this technology; hence, the development of clean and economical tar-removing technologies is becoming increasingly important. Catalytic tar removal has the advantage of avoiding expensive gas cleaning systems while maintaining the sensible heat in the producer gas. Catalysts derived from waste materials are an effective means of value addition to the waste. Red mud, a by-product of bauxite processing, has received considerable attention in this regard due to its high iron content in the form of ferric oxide, high surface area and its resistance to sintering and poisoning. The results from the study of developing red mud as catalysts for biomass tar reduction is presented, along with comments on future challenges.
