Influence of a glass wool hot vapour filter on yields and properties of bio-oil derived from rapid pyrolysis of paddy residues

► Rapid pyrolysis of paddy residues was carried out in a fluidised-bed reactor with a glass wool hot vapour filtration unit. ► The effects of pyrolysis temperature and the use of a glass wool hot vapour filter were investigated and reported. ► Characterisation of biomass from paddy residues was performed. ► Characterisation of bio-oil was performed using various analytical techniques. ► The use of glass wool hot filter could improve bio-oil quality.
