| Popis: | Steam methane reforming has been extensively used in producing syngas, but the H2/CO ratio of the syngas produced by the method is too large to feed to subsequent processes such as the Fischer–Tropsch process. The dry methane reforming process produces a syngas with a small H2/CO ratio. Combining these two processes makes it possible to adjust the H2/CO ratio to provide a syngas with a proper ratio for subsequent processes. Dry reforming is well-known to suffer a severe coke generation problem. If the two reactions occur simultaneously in one reactor, the coke generation problem can be greatly reduced by the presence of water in the reactor. However, this setup needs a catalyst suitable for both reactions in terms of both stability and performance, and no commercial catalyst has been reported to do this job. We propose a novel spatially patterned catalytic reactor in which two different catalysts, one suitable for steam reforming and the other suitable for dry reforming, are spatially layered. The catalys... |
