“…The release of poisonous mercaptans and coke deposits, on the surface of the catalyst for this system, is yet to be curtailed, however, in lieu of the impact of this technology on the environment, car manufacturers still deem it a suitable/considerable option to use H 2 as power source for fuel cells. Do et al [28] succeeded in producing hydrogen from propane via hydrothermal/steam reforming, which was aided by a nickel-based catalyst supported on AlSi x O y , where they established the effect of acidity on the performance of the catalyst at high temperatures (i.e. 200-600 • C); they adopted a steam to propane ratio of 1:6, which makes the process somewhat highly energy intensive and expensive in terms of overhead cost of the entire process per kg hydrogen produced.…”

Practically, an ideal catalyst for Formic acid-decomposition is one that best suits the reaction and significantly lowers its activation energy and improves the reaction rate under favourable conditions. Several catalysts for Formic Acid (FA)-decomposition reactions were examined. Based on the volcano curve and the potential of copper to give high hydrogen yields, emphasis was placed on a Cu-catalysed reaction as potential system for sustainable hydrogen production. Some recent advances in hydrogen production from formic acid were discussed and an effective system for FA-decomposition for hydrogen production was proposed. Since helium can be stored in weather balloons and weighs almost the same as hydrogen, a hydrogen buffer made from polyester fabric and coated with polyurethane or a hydrogen cylinder/tube was proposed for storing hydrogen for use as transportfuel. Also, due to the nature of the mechanisms/pathways describing FA-conversion reactions at the sites or surfaces of the copper-nanocatalysts, it is evident that the Cu(2 1 1) coordination site possesses the highest activation energy relative to those of Cu(1 0 0) and Cu(1 1 1), hence, the reason for the noticeable high or low hydrogen yields. Thus, the potential of Cu giving high hydrogen yields from FA spans from the reactions of FA at the Cu(1 1 1) and Cu(1 0 0) sites.

Steam reforming is a method for producing hydrogen gas as a solution for renewable energy generation. One source of hydrogen in a steam reformer is propane gas. The advantage of propane gas is the ease of transportation and storage. The production of hydrogen gas in a steam reformer is certainly influenced by supporting factors such as the temperature of the reformer. In this study, propane steam reforming was simulated in 3D with COMSOL Multiphysics 5.3ª software with bed reformer temperatures varying from 600, 650, 700, 700, 750, 800 and 850 o C with steam to carbon (S/C) ratio 3. The results show that increasing the temperature causes the density of the reformer to decrease, which in turn results in increased gas velocity. In addition, an increase in temperature in the bed reformer increases propane conversion to 87.8% and produces about 40% hydrogen at 850 o C.
