An apparatus for converting carbonaceous raw materials into a carbonized product and activating the product, includes a device for heating the carbonaceous raw materials to form a carbonized product, and equipment for activating the carbonized product and supplying by-product of the activation to the device to help in the heating. The device heats a column of carbonaceous raw materials to pyrolize it and form a carbonized product and vapors and gases. Upward flow of the gases and vapors is restrained so that they flow, with the carbonized product, out of the bottom of the column where they are burned in a combustion box and the resultant hot gases used to heat the column through a tube defining the column. Descending carbonized materials pass rapidly through the combustion box into the equipment which through electical resistance heating and steam, activates the carbonized materials and passes gas and vapor by-products thereby created up into the combustion box to help fuel the heating of the raw materials.
An apparatus for carbonizing carbonaceous raw materials, comprising a tube having a bottom for holding a column of carbonaceous raw materials, a mechanism for subjecting the column to heat and pyrolysing the raw materials to produce a carbonized product and gases and vapors and deliver them through the bottom of the tube, and a device for burning the gases and vapors at the bottom of the tube and using the heat generated thereby to heat the column, wherein the burning device includes a separator to dissever the gases and vapors from the carbonized product wherein the burning device includes a combustion box and the separator is mounted above the combustion box and restrains downward movement of the column, wherein the carbonized product is delivered through the bottom of the combustion box, and the apparatus further includes a reactor for receiving the carbonized product and activating it and for passing by-product gases and vapors thereof to the combustion box for burning.
