An apparatus for production of a carbon product from a biomass source, the apparatus including a reactor having a hollow body configured to receive the biomass source therein. The hollow body has a proximal end with an entry opening and a distal end with an exit opening, and a load zone between the proximal end and the distal end. The apparatus further includes an entry mover at the proximal end of the hollow body and movable between the proximal end and the distal end, and an exit mover within the hollow body positioned distal to the entry mover. The apparatus further includes at least one heating element configured to heat at least one heating zone of the hollow body. A method of producing a carbon product from a biomass source is also disclosed.
