Hydrogen production by direct contact pyrolysis of natural gas

M Serban, MA Lewis, CL Marshall, RD Doctor - Energy & fuels, 2003 - ACS Publications
In this paper, we propose the concept of utilizing the heat generated in Generation IV
nuclear reactors to produce hydrogen and carbon from methane or natural gas by direct
contact pyrolysis, a process that features zero greenhouse gas emissions. Methane or
natural gas was bubbled through a bed of either low-melting-point metals (eg, lead or tin),
granular or catalytic materials (eg, silicon carbide, α-alumina, NiMo/γ-alumina), or a
mechanical mixture of molten metal and solid media. The methane conversions were found …

Currently petroleum refining is by far the biggest consumer of pure hydrogen, but the major
petroleum companies and vehicle manufacturers, are orienting their industry towards a
hydrogen economy. Motivations for exploring hydrogen as the leading alternative energy
are to assure a future energy supply through a renewable energy source, and to solve
global environmental problems through reducing CO2 emissions, and improving air quality.
It is predicted that the world demand for hydrogen will grow by 10%/yr over the next five …
