Abstract:
Hydrogen is projected to be one of the primary energy sources in the 21st century. It has the highest specific energy content of all conventional fuels and is the most abundant element. The three main methods for producing hydrogen from heavy hydrocarbons are: Steam reforming (SR), Partial oxidation (PDX) and Auto-thermal reforming (ATR). In the present work, the catalytic partial oxidation of isooctane for the production of hydrogen over nickel/alumina catalyst for in fixed bed reactor has been considered. A steady state one-dimensional non-isothermal model have been developed to simulate the partial oxidation of isooctane using oxygen in first fixed bed reactor (FBR-1) and air in second reactor '(FBR-2) as oxidants over a Nickel/alumina catalyst to produce hydrogen. The variations of conversion of isooctane and conversion of oxygen with inlet temperature, pressure, C/O ratio in feed and residence time have been shown in both reactors
