Abstract
This research focuses on the catalytic effect of nickel foam metal through steam reforming of methane. The experiments were conducted under the conditions of steam-carbon (S/C) ratio of 22.2, 16.4, and 5.01. The results showed that almost all of the produced syngas is composed of H_2 and CO for S/C=22.2 and 16.4, which may be one of the peculiar features of this nickel foam metal. Also, the conversion reaches 95.2% under the condition of S/C=22.2. On the other hand, coking was observed with low S/C, which led to catalytic effect instability during reforming. It is expected that, by separating H_2 from syngas using hydrogen separation membrane and lowering its concentration, more H_2 would be produced from CO rich gas through shift reaction.
