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 DEG C and 1000 DEG 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 synthesise graphitic material with a desired morphology.

Description

technical field [0001] The present invention relates to a method of controlling the morphology of graphite during the production of graphite. Background technique [0002] Solid carbon, or more specifically graphite, is considered a key material in the emerging green technology market. It has proven useful in energy storage, electric vehicles, photovoltaics and modern electronics. Since different forms of graphite exhibit different properties, the commercial use of graphite is also highly dependent on the form. [0003] According to reaction formula (1), natural gas can be catalytically cracked into solid carbon and hydrogen. [0004] CH 4 →C+2H 2 (1) [0005] ΔH 裂解,298K =74.81kJ / mol, ΔG 裂解,298K =50.72kJ / mol [0006] In this method, solid carbon material is deposited on the surface of the catalyst and hydrogen gas is released. There are many known catalysts that can be used in this method, including noble metal, transition metal and carbon-based catalysts. [0007...
