Fuel properties of glycerol/methanol/bio-oil/biochar (GMBB) bioslurry fuels are investigated.
HHV, density and surface tension of GMBB bioslurry fuels increase with biochar loading level.
Methanol and glycerol slow down the ageing of the GMBB bioslurry fuels.
Methanol and glycerol reduces the leaching of AAEM species from biochar during bioslurry ageing.
