Abstract: The invention provides a method of sequential pyrolysis and carbon deposition to produce a composite carbonaceous product, the method comprising: a pyrolysis process step comprising pyrolyzing a pyrolyzable organic feed at a pyrolysis temperature in a first reaction zone in the presence of a non-oxidising gas to produce hot char and pyrolysis gas, wherein the pyrolysis gas and the non-oxidising gas combine to form a gas mixture; discharging the gas mixture from the first reaction zone to a combustion zone and combusting at least a portion of the pyrolysis gas therein, wherein heat produced by the combusting of the pyrolysis gas is transmitted from the combustion zone to the first reaction zone to provide at least a portion of the heat of pyrolysis; and a decomposition process step comprising contacting a hydrocarbon-rich organic gas with the hot char directly after its production in the pyrolysis process step, wherein the hydrocarbon-rich organic gas catalytically decomposes on the hot char at a decomposition temperature which is higher than the pyrolysis temperature, thereby producing gaseous decomposition products comprising hydrogen and a composite carbonaceous material comprising the char with carbon deposits thereon.

Abstract: The invention provides a system for pyrolysis, comprising: (i) a gas producer comprising a gasification zone and a producer gas outlet, wherein the gas producer is configured to: oxidise at least one carbon-containing feed in the presence of an oxidising gas in the gasification zone to form a producer gas; and discharge the producer gas from the gasification zone via the producer gas outlet, wherein a residual oxygen content of the producer gas is substantially depleted or maintained below a maximum predetermined amount by controlling a ratio of oxygen fed to the gasification zone to the carbon-containing feed, (ii) a pyrolyzer comprising a pyrolysis zone and one or more pyrolyzer gas outlets, wherein the pyrolyzer is configured to: feed the producer gas discharged from the gasification zone to the pyrolysis zone; pyrolyze a pyrolyzable organic feed in the pyrolysis zone in the presence of the producer gas to produce a carbonaceous pyrolysis product and a gas mixture comprising combustible components comprising pyrolysis gas; and discharge the gas mixture from the pyrolysis zone via the one or more pyrolyzer gas outlets, and (iii) a first combustor comprising a combustion zone, wherein the first combustor is configured to: receive the gas mixture discharged from the pyrolysis zone in the combustion zone; feed an oxygen-containing gas to the combustion zone; and combust at least a portion of the combustible components present in the gas mixture in the combustion zone to produce a combustion product gas.
