Webreforming of heptane (Chen et al., 2003a,b, 2004). Also, the re-quired heat per carbon atom of heptane is less than methane and the heat duty will be less (Rostrup-Nielsen et al., 1998). WebThe reported hydrogen yield from steam reforming of heptane in a fixed bed reformer is about 2.0 at 723K and 1489kPa [27]. While the simulated hydrogen yield in the CFFBMR is about 2.4, which is the equilibrium hydrogen yield. Both the experimental and simulation results show that the steam reforming system suffers from the thermodynamic ...
