A biomass fractionation apparatus includes a vessel having a processing chamber, an inlet configured to receive a biomass into the processing chamber, and an outlet configured to discharge processed biomass from the chamber. A bed plate is movably positioned within the processing chamber and includes a plurality of elongated fins extending outwardly therefrom in substantially parallel spaced-apart relationship. A cylindrical rotor is rotatably secured within the processing chamber in adjacent, spaced-apart relationship with the bed plate. The rotor has a plurality of elongated blades extending radially outwardly therefrom in circumferentially spaced-apart relationship. Upon rotation of the rotor, the blades are configured to accelerate a biomass within the processing chamber against the fins of the bed plate and to cause the bed plate to pulsate against the rotor.

A high-efficiency pyrolysis apparatus comprises a first pyrolysis furnace, a second pyrolysis furnace, a fractional distillation device, and an air sucking device. The first pyrolysis furnace heats and pyrolyzes a solid-state waste. The second pyrolysis furnace interconnects with the first pyrolysis furnace through a first channel and generates a fluid. The fractional distillation device interconnects with the second pyrolysis furnace through a second channel and performs a fluid separation operation on the fluid. The air sucking device interconnects with the first pyrolysis furnace and generates a negative pressure to the first channel and the second channel to prevent from that air exists in the first pyrolysis furnace and the second pyrolysis furnace and that toxic materials are generated in the first pyrolysis furnace and the second pyrolysis furnace. The high-efficiency pyrolysis apparatus is less likely to generate toxic materials and thus less likely to pollute the air.
