A process for pyrolyzing biomass comprises pyrolyzing cellulosic biomass in a fast pyrolysis chamber by heating the cellulosic biomass to a pyrolyzation temperature to generate a pyrolysis vapor flow therefrom. The pyrolysis vapor flow is directed from the fast pyrolysis chamber along a vapor flow conduit to a condensation trap at a temperature sufficient to condense the vapor to liquid and generate a thermal gradient along the vapor flow conduit between the pyrolysis chamber and condensation trap. A majority of the pyrolysis vapor flow along the vapor flow conduit to the condensation trap is achieved by natural convection. Systems that can practice this process are also disclosed.

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.
