Effects of catalytic bed position on hydrogen production by methane decomposition
Journal of Mechanical Engineering and Sciences, 2022 COx free hydrogen can be produced by thermal decomposition of methane. Such process is carried out in a fixed bed catalytic reactor. Where heterogeneous catalytic reaction occur when methane come in contact with catalyst bed at a temperature range of ...

CPFD SIMULATION OF A FIXED BED GASIFICATION REACTOR [PDF]
WIT Transactions on Ecology and the Environment, 2020 Biomass gasification is regarded as one of the most promising energy recovery technologies. The gases produced from the biomass gasification can be used for heat and power production. Alternatively, they can be used for the production of liquid biofuel. Fixed bed downdraft gasification reactors are easier to use in small scale gasification processes. A

Pyrolysis of Tyre Waste in a Fixed-Bed Reactor
Symmetry, 2023 This paper presents the results of investigations on the pyrolysis of tyre waste in a laboratory fixed-bed batch reactor. The results regarding the influence of either the reaction temperature (425, 450, 475, and 500 °C) and the flow of the inert gas (0, 100, 300, and 500 mL/min) on product yield (referred to as pyrolysis of waste tyres) are also ...
