Whereas pyrolytic decomposition of hydrocarbons typically produces unstructured carbon, the nanoplatelets are characterized by dimensions of 200 â 500 nm, occurring in stack of 2-6 with morphology resembling mildly crumpled paper. Methane conversion can reach 90% with selectivity to products determined by the effluent streamâs temperature regime. Accompanying spectral diagnostics are used to characterize the reacting flow. The complement CCBA material has structure analogous to that of commercial high-value conductive carbon blacks, with high electrical conductivity higher than that of some commercially available conductive carbon blacks. These results highlight the importance of advanced plasma technology for the economic utilization of natural gas by producing premium carbon materials.
The co-production of hydrogen and high-value carbon materials from natural gas offers opportunities to reduce the costs associated with large-scale production of industrial or fuel hydrogen or platform chemicals while also producing synthetic, high-value carbon products such as the graphene nanoplatelets. H Quest Vanguard Inc. is developing microwave plasma processing of natural gas as a modular, compact and portable technology for production of hydrogen and premium carbon products.
