Pyrolysis

Pyrolysis is the decomposition of organic matter at elevated temperatures (300 and 1300 °C) in the absence of oxygen at atmospheric pressures. The useful products generated are a charcoal-like biochar solid product, a bio-oil formed from ‘condensable’ volatile substances and ‘non-condensable’ gases which may include both carbon dioxide and methane.

Anaerobic digestion optimization through thermal hydrolysis pre-treatment

Pre-treatment of sludge by thermal hydrolysis upstream of anaerobic digestion is used to improve AD efficiency. A study looked at (pre-)commissioning data for a full-scale AD installation undergoing upgrading with TH to assess the basis for optimisation.
