چکیده انگلیسی
The main conclusions were: Karl-Fischer titration is recommended for analysing water in pyrolysis liquids. the solids content determined as ethanol insolubles is accurate for white wood (stem wood, no bark or needles) liquids, while a more powerful solvent, like a mixture of methanol and dichloromethane (1:1 vol.%), is required for extractive-rich liquids from feedstocks such as forest residues. for elemental analysis at least triplicates are recommended due to the small sample size. Special attention should be paid to nitrogen standards. They should have a similar range of nitrogen as the sample. Kinematic viscosity is an accurate method at 40 °C for pyrolysis liquids. Rotating viscotesters with a cover at low temperatures (â¤50 °C) can also be used. Stability index needs more specific instructions. Results of chemical characterisation were not very consistent. Proper standard solutions have to be used with known amounts of compounds for quantitative analyses.
