shows heptane conversion at different reaction side pressures of 20.0 bar, 25.0 bar and 30.0 bar. The CFFBMR gives 100% conversion of heptane at the beginning of the reformer for all reaction side pressures at almost the same reactor length. The corresponding hydrogen yield profiles are shown in Fig. 8. The increase of the reaction side pressure has direct strong influence on the hydrogen permeation driving force. Substantial improvement of hydrogen yield is achieved by increasing the reaction side pressure. For example the increase of the reaction side pressure from 20.0 bar to 30.0 bar gives 25.9% increase in hydrogen yield. Fig. 9 shows the corresponding H2/CO ratio at various reaction side pressures. It is clearly shown that the increase of the reaction side pressure has also strong influence in reducing the H2/CO ratio. At a reaction side pressure of 30.0 bar the exit H2/CO is 1.61. Hence, the industrial range of the H2/CO ratio has been satisfied. The influence of the increase of the reaction side pressure on methane yield is shown in Fig. 10. The increase of the reaction side pressure has another positive effect of reducing the methane yield. However, the increase of the reaction side pressure produces more carbon dioxide as shown in Fig. 11. The carbon dioxide can be used for other processes such as dry reforming of methane rather than harming the environment.
