A method of continuously recovering hydrocarbons from carbon ores can include providing first and second vessels containing rubblized carbon ore. A cooling fuel gas can be introduced into the first vessel. The cooling fuel gas can include oxygen and a recycle gas from the second vessel, which includes hydrocarbons and oxidation products. The oxygen can be consumed through oxidation in an oxidation zone in the first vessel. The temperature of the oxidation zone can be controlled by limiting the oxygen concentration in the cooling fuel gas. This can produce a hot oxidation product gas that heats rubblized carbon ore in a pyrolysis zone downstream of the oxidation zone. Gaseous and vapor hydrocarbons can be produced in the pyrolysis zone. The vapor hydrocarbons can be condensed in a condensing zone downstream of the pyrolysis zone and then collected. The remaining gaseous hydrocarbons and oxidation products can be recycled as the recycle gas. The oxidation zone and the pyrolysis zone can continuously move through the rubblized carbon ore in a downstream direction. Optionally, by using nitrogen free oxygen for the oxidation, a nitrogen free stream of carbon dioxide is produced suitable for carbon dioxide capture and management. This can also eliminate the production of NOx in the oxidation process.

Systems and methods are provided for production of carbon nanotubes and H.sub.2 using a reaction system configuration that is suitable for large scale production. In the reaction system, a substantial portion of the heat for the reaction can be provided by using a heated gas stream. Optionally, the heated gas stream can correspond to a heated H.sub.2 gas stream. By using a heated gas stream, when the catalyst precursors for the floating catalyst-chemical vapor deposition (FC-CVD) type catalyst are added to the gas stream, the gas stream can be at a temperature of 1000° C. or more. This can reduce or minimize loss of catalyst precursor material and/or deposition of coke on sidewalls of the reactor. Additionally, a downstream portion of the reactor can include a plurality of flow channels of reduced size that are passed through a heat exchanger environment, such as a shell and tube heat exchanger. This can provide cooling of the gas flow after catalyst formation to allow for carbon nanotube formation, while also reducing the Reynolds number of the flow sufficiently to provide laminar flow within the region where carbon nanotubes are formed.
