Literature review of the catalytic pyrolysis of methane for hydrogen and carbon production
This review highlights recent developments and future perspectives in COx-free hydrogen production through methane pyrolysis. We give detailed discussions on thermal and catalytic methane cracking into hydrogen and carbon. Various types of solid and liquid catalysts were reviewed in terms of hydrogen selectivity, methane conversion, and deactivation. Some pilot scale technology was discussed; however, large-scale industrialisation is impeded by rapid solid catalyst deactivation, low-priced carbon (by-product) of molten catalysts, harsh conditions for reactor materials, and performance of stable molten catalysts. For catalytic methane cracking in molten catalysts (salt or metal), substantial advances in catalyst development, product separation, and reactor design are still required to commercialise methane pyrolysis for hydrogen production. To provide guidance to future works in this area, the review is specifically focused on (i) design of catalysts (ii) recent developments of molten salt-based methane cracking, (iii) reactor design and process design.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
