Abstract
In one aspect, a process to decompose a hydrocarbon such as methane into carbon (graphitic powder) and hydrogen (H2 gas) without secondary production of carbon dioxide, employing a cycle in which a secondary chemical can be recycled and reused, is disclosed.
Claims22
A process for producing hydrogen, comprising:
- reacting a hydrocarbon and a metal salt to produce a hydrogen-containing gaseous product and a solid product that comprises carbon;
- and
- wherein the hydrogen-containing gaseous product and solid product react to produce the metal salt and hydrogen gas.
A process for producing hydrogen, comprising:
- reacting methane or ethane and a metal salt to produce a hydrogen-containing gaseous product and a solid product,
- wherein the hydrogen-containing gaseous product and solid product react to produce the metal salt and hydrogen gas,
- wherein the metal salt is a metal halide in which the metal comprises zinc, calcium, magnesium, manganese, cobalt or nickel.
