A solids content of 60-65 by weight is recommended during the conditioning process for optimal reagent use efficiency and separation selectivityHowever this high solids content can cause problems for conditioners causing them to sand upthe rotary drum conditioner mitigates this issue by keeping the particles in suspension.
As the field of fast pyrolysis has matured it has been accompanied by a kind of orthodoxy in its practiceAmong these orthodoxies are the following: 1 oxygen should be excluded from the pyrolysis process; 2 little sugar is produced during pyrolysis; and 3 the major product of pyrolysis is a low-value emulsion in waterAdherence to these tenets is an impediment to the commercial.
