Abstract
A process of controlling the morphology of graphite in a process for the production of graphite, the process comprising: contacting at elevated temperature, a metal-containing catalyst with a hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and carbon; wherein the temperature is between 600° C. and 1000° C. and a pressure between 0 bar(g) and 100 bar(g), and wherein both the temperature and the pressure are set within predetermined value ranges to selectively synthesize graphitic material with a desired morphology.
Claims17
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.
