Claims20
A biomass waste processor, comprising:
- a biomass feedstock storage, the biomass feedstock storage operative to store biomass feedstock at a fixed storage temperature, the fixed storage temperature in a range of 13° C. to 30° C.;
- a biomass feedstock dryer coupled to the biomass feedstock storage, the biomass feedstock dryer operative to increase the temperature of the biomass feedstock to a range of 200° C.-300° C.;
- a biomass feedstock shredder coupled to the biomass feedstock dryer, the biomass feedstock shredder operative to shred the biomass feedstock into particles sized from 2 mm to 1 cm in diameter;
- a first reaction chamber coupled to the biomass feedstock shredder, the first reaction chamber operative to perform torrefaction of the biomass feedstock at a fixed temperature to produce a combination of torrefied biomass and syngas, the first reaction chamber comprising electric heating elements to maintain the fixed temperature within the first reaction chamber;
- a second reaction chamber coupled to the first reaction chamber, the second reaction chamber operative to perform pyrolysis of the torrefied biomass at a fixed temperature to produce syngas and one of:
- biochar and activated carbon, the second reaction chamber comprising electric heating elements to maintain the fixed temperature within the second reaction chamber;
- a third reaction chamber coupled to the first reaction chamber, the third reaction chamber operative to perform pyrolysis of the torrefied biomass at a fixed temperature to produce syngas and one of:
- biochar and activated carbon, the third reaction chamber comprising electric heating elements to maintain the fixed temperature within the second reaction chamber;
- a gas extractor, the gas extractor coupled to the second reaction chamber and the third reaction chamber, the gas extractor operative to extract syngas from the second reaction chamber and the third reaction chamber during pyrolysis;
- and
- an electricity generation system, the electricity generation system operative to produce electricity for the biomass waste processor.
