Sewage sludge valorization by pyrolysis using a mechanically fluidized reactor

摘要

1. Bio-oil yield, calorific value and water content are functions of pyrolysis process and fractionation scheme. 2. Both fractionation schemes are effective de-watering techniques. 3. Through optimisation of the fractional condensation scheme (series), a bio-oil with a calorific value of ～35 MJ/kg and water content of ～1.5 % is achievable. 4. Good recovery for most inorganics in char, except for sulphur.
