Evaluation of thermodynamically favourable operating conditions for production of hydrogen in three different reforming technologies

摘要: Abstract With the aid of thermodynamic analysis using AspenPlus™, characteristics three different types reforming process are investigated. These include: steam-methane (SMR), partial oxidation (POX) and autothermal (ATR). Thereby, favourable operating conditions identified for each process. The optimum steam-to-carbon (S:C) ratio SMR reactor is found to be 1.9. air POX 0.3 at a preheat temperature 312 °C. S:C ATR 0.29 0.35, respectively 400 °C. Simulated material energy balances show that CH4 flow rates required generate 1 mol s−1 hydrogen 0.364 mol s−1 POX, 0.367 mol s−1 0.385 mol s−1 SMR. results demonstrate system has lowest cost produce same amount from CH4.
