Abstract

Structural simplicity is one of the advantages of an autothermal reforming(ATR) reactor. ATR reactor needs no heat-supplying devices such as burners and heat exchanger. The heat balance in an ATR reactor is dependent on operation parameters and they should be carefully determined for reactor stability and high efficiency. To study operation conditions of an ATR reactor, a packed-bed ATR reactor with a commercial catalyst was designed and constructed. Operation parameters such as O₂/C, H₂O/C and GHSV (gas hourly space velocity, /h) were varied and the resultant behavior of the reactor was characterized by analyzing product compositions and monitoring temperatures at various points inside the reactor during operations. Effects of operation parameters on the product compositions in the experiment were different from those predicted by thermodynamic calculations. The difference can be attributed to dependence of the temperature on operation parameters in the real reactor which the thermodynamic calculation does not take into account.
