Carbon production by thermal methane cracking in tubular quartz reactor

Methane cracking is explored as a bridge technology that enables the production of hydrogen while capturing carbon in the form of valuable materials, which could potentially lower hydrogen production costs and reduce carbon emissions. The process of methane (CH 4 ) cracking consists in the conversion CO molecules into carbon and hydrogen CH 4(g) = C (s) + 2H 2(g) 2-free of methane The valorization of the carbon product plays a crucial role in reducing H 2 (1) prices and improving overall process economics. To achieve this, a comprehensive understanding of the complex network of reactions involved in methane thermal cracking is essential, particularly in relation to the formation of valuable carbon and unwanted byproducts such as carbon nanoparticles. The study focuses on the experimental analysis and kinetic modelling of methane cracking in a tubular quartz reactor, exploring the morphology of the carbon products.
