Adsorption Characteristics of Biooil on Biochar in
This study reports the adsorption characteristics of biooil on biochar in biochar/biooil slurry (i.e., bioslurry) systems at three biochar loading levels (2.4, 4.8, and 16.7%, respectively). At low biochar loading levels (2.4 or 4.8%), heavy organic compounds (particularly those containing fused aromatic systems) in biooil was selectively adsorbed onto the biochar.

WikiZero Pyrolysis
Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition.The word is coined from the Greekderived elements pyro "fire" and lysis "separating".. Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood. In general, pyrolysis of organic

If the goal of fast pyrolysis is to produce a biooil with the lowest oxygen and highest carbon content, the conditions to use are 600°C with a residence time longer than 1.5 seconds. However, under these conditions the biooil yield is significantly less than at lower temperatures and shorter residence times, ~14 wt% biooil at 600°C, RT 3.5
