{"title":"Analysis of a Secondary Autothermal Reformer Using a Thermodynamic POX Model","authors":"Akbar Zamaniyan, Alireza Behroozsarand, Hadi Ebrahimi","volume":25,"journal":"International Journal of Chemical and Molecular Engineering","pagesStart":81,"pagesEnd":86,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/7735","abstract":"Partial oxidation (POX) of light hydrocarbons (e.g.\nmethane) is occurred in the first part of the autothermal reformer\n(ATR). The results of the detailed modeling of the reformer based on\nthe thermodynamic model of the POX and 1D heterogeneous\ncatalytic model for the fixed bed section are considered here.\nAccording to the results, the overall performance of the ATR can be\nimproved by changing the important feed parameters.","references":"[1] Bharadwaj, S. and L.
