“…They found that (1) the surface chemistry and the pore size distribution played an important role in the initial conversion rate of methane and the long-term sustainability of the catalyst, respectively, (2) microporous carbons with high content of oxygenated surface groups exhibited high initial conversion rates but they became rapidly deactivated, and (3) mesoporous carbons with high surface area provided more stable and sustainable hydrogen production. Recently, Serrano et al [23] used ordered mesoporous carbons as catalysts for methane decomposition using a thermobalance. The results showed that OMC had remarkable stability as compared with carbon black and activated carbon due to its unique ordered mesopore system.…”

This article reports on the use of mesoporous carbons as catalysts for hydrogen production by thermocatalytic decomposition of methane. The prepared ordered mesoporous carbons (OMCs) and commercial carbon materials (including disordered microporous carbon, mesoporous carbon, and carbon nanotube) were tested for their catalytic activities for methane decomposition in a fixed-bed reactor. Characterizations by different techniques including gas adsorption, x-ray photoelectron spectroscopy, and transmission electron microscopy were carried out for the pristine and used catalysts. Results showed that the initial activity was related to the chemical structure of the catalysts such as defects, while the long-term activity was related to the physical characteristics such as the BET surface area and pore volume. Unlike disordered carbons, OMCs with relatively larger uniform pores could maintain a steady catalytic activity for a longer time, followed by a sharp activity decline due to the blockage of most of the pores. It is conceived that by designing and preparing carbon materials with ideal pore systems using the replication method, it is possible to enhance the catalytic activity and stability of the reaction.

Methane pyrolysis using a molten metal process to produce hydrogen is compared to steam methane reforming (SMR) for the industrial production of hydrogen. Capital and operating cost models for pyrolysis and SMR were used to generate cash‐flow and production costs for several different molten pyrolysis systems. The economics were most sensitive to the methane conversion and the value obtained for the solid carbon by‐product. The pyrolysis system at 1500 °C is competitive with a carbon tax of $78 t−1; however, if a catalytic process at 1000 °C were developed using a conventional fired heater, it would be competitive with SMR without a carbon dioxide cost penalty. Several pyrolysis alternatives become competitive with increasing carbon dioxide taxes.
