Analyses Of Hydrogen Production From Sub-Quality Natural Gas (Ii): Stem Reforming And Autothermal Stem Reforming Of Sqng


Steam reforming of sub-quality natural gas (SRSQNG) can be a more desirable approach for hydrogen production than direct thermolysis of SQNG because the processes produce two more moles of hydrogen via water splitting. A Gibbs reactor unit operation in the AspenPlus™ chemical process simulator has been employed to carry out equilibrium calculations for the SQNG + H2O and SQNG + H2O + O2 systems. Water and oxygen inlet flow rates do not significantly affect the decomposition of H2S at < 1000°C. The major co-product of the processes is carbonyl sulfide while sulfur dimer and carbon disulfide (CS2) are minor by-products within this temperature range. At > 1300°C), CS2 and sulfur dimer become major co-products. No acid gas components are generated. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
