Decentralized Production Of Hydrogen From Hydrocarbons With Reduced Co 2 Emission

Keywords

Abstract

Currently, most of the industrial hydrogen production is based on steam methane reforming process that releases significant amount of CO2 into the atmosphere. CO2 sequestration is one approach to solving the CO2 emission problem for large centralized hydrogen plants, but it would be impractical for decentralized H2 production units. The objective of this paper is to explore new routes to hydrogen production from natural gas without (or drastically reduced) CO2 emissions. One approach analyzed in this paper is based on thermocatalytic decomposition (TCD) of hydrocarbons (e.g., methane) to hydrogen gas and elemental carbon. The paper discusses some technological aspects of the TCD process development: (1) thermodynamic analysis of TCD using AspenPlus™ chemical process simulator, (2) heat input options to the endothermic process, (3) catalyst activity issues, etc. Production of hydrogen and carbon via TCD of methane was experimentally verified using carbon-based catalysts.
