Title: Thermal decomposition of methane applied to reduce CO 2 emissions in natural gas
Thermal decomposition of methane (TDM) is an endothermic reaction that can be applied to
convert methane in natural gas to solid carbon and gaseous hydrogen. When a part of the carbon in
natural gas is taken out, the CO2 emissions in the natural gas combustion are reduced. The product
carbon may have commercial value that compensates for the lost heating value. The TDM process
was techno-economically analyzed when four different technologies were applied to conduct the
TDM reaction. The price of the product carbon was found as the most crucial factor affecting the
economic feasibility of the process.
