Obtaining Hydrogen by Thermocatalytic Decomposition of Methane Using a Catalyst ‘Nickel on Kieselgur’

Abstract

The process of hydrogen production through thermocatalytic decomposition of methane using a “nickel on kieselgur” catalyst on a quartz sand substrate with a thickness of 1 cm in the “sand-catalyst-sand” configuration was investigated in this work. The experimental results revealed a dependence of the percentage yield of hydrogen on temperature within the temperature range of 530°C to 770°C. As a result, a hydrogen content of 68% in the gas mixture was achieved at the reactor outlet under the conditions of 770°C temperature and a methane flow rate of 2 l/h.
