Abstract

A dry distillation reactor for a raw material of hydrocarbon with a solid heat carrier is provided. An inner component with a pore path or a pore space is arranged inside the reactor to form a flow channel for the gas-phase product of the dry distillation. Also a dry distillation method using the dry distillation reactor is provided. The dry distillation method includes moving the reacting materials from top to bottom; moving a gas-phase product of the dry distillation along a designed path in the reactor; and finally leading same out through an outlet arranged in a central collecting channel for the gas-phase product of the dry distillation.
