To this end, LIFE WASTE2BIOFUEL will develop an Integrated Gasification Fischer-Tropsch (IGFT) process for the thermal treatment of the biomass fraction of Municipal Solid Waste (MSW). The system shall allow treating the target waste through an energy sustainable and environmentally friendly process.
The biowaste, which have been previously dried at 10 % of humidity, feeds a pyrolysis reactor where the material is dehydrated and the condensable volatile fraction is separated (PYROGAS) from the fixed carbon fraction (CHAR). The volatile fraction is transformed into combustion gases once it has been treated by filtration and conditioned.
The char fraction feeds the gasification reactor where exothermic reactions take place, together with typical gasification reactions of the gaseous fraction.
The produced ashes are evacuated from the reactor and the obtained syngas is recirculated through the endothermic reactors (pyrolysis and drying) to recover the thermal energy.
Following, the syngas is moved to the separation of small particles state (volatile ashes) through high performance cyclones which are especially designed to work at high temperature.
Once the syngas is out of the washing system, it goes through a final treatment of security conditioning formed by metallic and coalescence filters, chiller and a heater in order to make sure that the residual solid particles are separated (< 5 micra).
The pilot plant will have a processing capacity of 450 tm waste/year, producing 128 tm of liquid fuel.
The liquid fuel will be used in the own truck fleet of waste collection in order to validate it.
