Abstract
In accordance with the present invention, there is provided a process for producing hydrogen and graphitic carbon from a hydrocarbon gas comprising: contacting at a temperature between 600° C. and 1000° C. the catalyst with the hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and graphitic carbon, wherein the catalyst is a low grade iron oxide.
Claims16
A process for producing hydrogen and graphitic carbon from a hydrocarbon gas comprising:
- contacting at a temperature between 600° C. and 1000° C. a catalyst with the hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and graphitic carbon,
- wherein the catalyst is a low grade iron oxide;
- wherein reacted catalyst is reduced and wherein unreacted catalyst is non-reduced;
- wherein the hydrocarbon gas is selected from the group consisting of methane, ethane, ethylene, propane, butane, and a mixture thereof;
- and
- wherein upon contact with the hydrocarbon gas the non-reduced catalyst fragments into micro- and nano-scale fragments from inter-granular pressure caused by graphite precipitation.

A process for producing hydrogen and graphitic carbon from a hydrocarbon gas comprising:
- contacting at a temperature between 600° C. and 1000° C. a catalyst with the hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and graphitic carbon,
- wherein the catalyst is a low grade iron oxide,
- wherein, the contacting the catalyst with the gas is performed in a plurality of pressurized reactors arranged in series, and
- wherein the reactors are arranged in series to allow catalyst to flow from a first reactor to a subsequent reactor and each subsequent reactor in the series is operated at a higher pressure than the reactor preceding it, allowing catalyst to travel to reactors of higher pressure.
