Decomposition of Natural Gas by Thermal Anoxic Processes
Original language description
Natural gas is widely used as a source of the pure hydrogen production in a process of catalytic cracking and steam reforming. Specific emissions of carbon dioxide from these processes are relatively low, reaching a value of about 55 g CO2 per 1 MJ of the lower heating value (LHV) of hydrogen obtained. Further decrease of CO2 emitted volumes can be reached when a carbon separation as soot, graphite or carbon rich organic compounds proceeds over the thermal natural gas treatment. This treatment is allothermic pyrolysis in the absence of molecular oxygen and any other oxygen-containing compounds. Thermal cracking of natural gas by an indirect heating can produce clean hydrogen for fuel purposes with specific emissions of CO2 ranging from about 10 to 25 gCO2/MJ. This hydrogen production process results in a 50-55 % loss of energy comparing to the natural gas energy as its LHV. Thermal cracking of natural gas in a temperature range of 1150-1250 °C permits to reach the highest hydrogen rec
