Pretreatment BioTrac, Heat and Chemical Recovery
Pretreatment is one of the most critical and challenging process step. The BioTrac is a continuously operated system, designed for “steam explosion” of the biomass which basically means:
- Steam heating of ligno-cellulosic material followed by rapid de-pressurization
- Hemicelluloses decompose to monomers and lignin is softened
- The biomass fibre structure is partly destroyed at dicharge
- Fibres, soft lignin and sugars create an excellent raw-material for pelleting
- The steaming based process is very safe
