Fully modularized mid-feed pyrolysis reactor with simultaneous multi-feed capabilities

A modular pyrolysis reactor having multiple simultaneous feeds, comprising:

• a lower vessel configured for receiving a first biomass material from a first biomass input unit, wherein a truncated cone-shaped rotatable grate is disposed in the lower vessel, and an outlet end of an input pipe of the first biomass input unit is formed at a center of a top of the rotatable grate, so that a side surface of the rotatable grate forms a core reaction zone of the pyrolysis reactor, and wherein a material distribution tower having a pointed apex and a bowl structure is disposed above the top of the rotatable grate, the pointed apex covering the outlet end of the input pipe of the first biomass input unit and having a base that extends radially outwardly substantially to an outer edge of the top of the rotatable grate;
• an upper vessel;
• and
• a middle vessel disposed between the lower vessel and the upper vessel, the middle vessel configured for receiving at least a second biomass material from at least one second biomass input unit, wherein an outlet end of an input pipe of the at least one second biomass input unit extends radially inward to a central region of the pyrolysis reactor that is substantially vertically above the pointed apex and bowl structure of the material distribution tower, and wherein the outlet end of the input pipe of the at least one second biomass input unit is provided with a valve which automatically closes under gravity.
