Abstract
Methods for activating charcoal resulting from biomass gasification are provided. Exemplary methods include gasifying biomass in a gasification reactor of an integrated biomass gasification system to produce charcoal; and activating charcoal using heat generated from an integral heat source of the integrated biomass gasification system. The methods include activation of charcoal resulting from biomass gasification in a more efficient, economical manner, thereby increasing the value of biomass gasification with minimal investment in the process.
Claims20
A method of activating charcoal resulting from gasification, said method comprising:
- gasifying dried biomass material in a gasification reactor of an integrated biomass gasification system to produce charcoal;
- and
- activating the charcoal using heat generated from an integral heat source of the integrated biomass gasification system.
A method of activating charcoal resulting from gasification, said method comprising:
- gasifying dried biomass material in a gasification reactor of an integrated biomass gasification system to produce a stream of charcoal and producer gas;
- separating the charcoal from the producer gas of the stream using a hot screw conveyor;
- and
- activating the charcoal using heat generated from an integral heat source of the integrated biomass gasification system.
A method of activating charcoal resulting from gasification, said method comprising:
- gasifying dried biomass material in a gasification reactor of an integrated biomass gasification system to produce a stream of charcoal and producer gas;
- separating the charcoal from the producer gas of the stream using a hot screw conveyor;
- combusting the producer gas using a combustor to generate hot exhaust gases;
- and
- activating the charcoal using heat from the hot exhaust gases.
The method in accordance with 15 further comprising sun- drying the biomass material.
