Hydrogen production by catalytic cracking of methane over nickel gauze under periodic reactor operation
The catalytic cracking of methane over nickel gauze is proposed as an attractive alternative for the production of GO-Free hydrogen. The catalyst deactivates due to intensive coke deposition. Therefore, the reactor was operated periodically with the reaction followed by the catalyst regeneration by burning of coke in oxidative atmosphere. The optimal reaction performance was found to consist of reaction periods of 4 min followed by 4 min regeneration periods.
