1. A process comprising:
pre-treating a naturally occurring polycrystalline iron oxide catalyst, wherein the pre-treatment comprises heating;
providing the pre-treated catalyst to a fluidized bed reactor;
in the fluidized bed rector, contacting at an elevated temperature, the pre-treated catalyst with a hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and carbon and thereby selectively synthesise carbon material; and
extracting from the fluidized bed reactor a first stream which includes the synthesised carbon material and a second stream comprising the hydrogen.
