Study Findings from Wroclaw University of Technology Provide New Insights into Bioresource Technology

June 3, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Bioresource Technology are discussed in a new report. According to news reporting originating from Wroclaw, Poland, by VerticalNews correspondents, research stated, "Torrefaction is suggested to be an effective method to improve the fuel properties of biomass and gasification of torrefied biomass should provide a higher quality product gas than that from unprocessed biomass. In this study, both raw and torrefied Miscanthusxgiganteus (M x G) were gasified in an air-blown bubbling fluidized bed (BFB) gasifier using olivine as the bed material."

Our news editors obtained a quote from the research from the Wroclaw University of Technology, "The effects of equivalence ratio (ER) (0.18-0.32) and bed temperature (660-850 degrees C) on the gasification performance were investigated. The results obtained suggest the optimum gasification conditions for the torrefied MxG are ER 0.21 and 800 degrees C. The product gas from these process conditions had a higher heating value (HHV) of 6.70MJ/m(3), gas yield 2m(3)/kg(biomass) (H-2 8.6%, CO 16.4% and CH4 4.4%) and cold gas efficiency 62.7%."

According to the news editors, the research concluded: "The comparison between raw and torrefied M x G indicates that the torrefied M x G is more suitable BFB gasification."
