The CO2 reforming of coke oven gases (COG) was carried out over a Ni/γAl2O3 catalyst in order to obtain a suitable syngas for methanol synthesis. The influence of different operating conditions, such as temperature and volumetric hourly space velocity (VHSV), was studied. It was found that the H2 present in the feed gas promotes the Reverse Water Gas Shift reaction (RWGS), which produces water....

2. Productivity at this level means that the production costs of H 2 (expressed as the cost in US dollars per joule of calorific value contained in the molecule) are two to three times higher than for natural gas 4,5. However, taking into account the transportation and distribution costs of natural gas, and how pure you want the H 2 to be, the comparative cost of H 2 production can vary. Biomas...

Renewable hydrogen may be produced in the near term at a cost that is competitive with natural gas reforming by integrating hydrogen production with existing industrial utilization of agricultural residues. A team of government, industrial, and academic organizations is developing a steam reforming process to be demonstrated on the gaseous byproducts from a process for making activated carbon f...

1. Introduction Already in 1868 [1], H 2 was produced by the steam reforming (eq.1) of hydrocarbons in the presence of a calcium oxide, and the use of natural calcium-based sorbents as candidates to remove CO 2 in situ from reactors has been receiving increasing attention. Through simultaneous CO 2 absorption (eq.3) the equilibrium of the homogenous water gas shift reaction (eq.2) is shifted to...

In this study, the modeling of hydrogen production process in microreactors by methanol-steam reforming reaction is investigated. The catalytic reaction of methanol-steam reforming producing hydrogen is simulated considering a 3D geometry for the microreactor. To calculate diffusion among species, mixture average correlations are compared to Stephan-Maxwell equations. The reactions occurring in...

the request for natural gas attention to its adaption with environment and less pollution than the other fossil fuels has the highest growth in last decades. in result this energy has high geopolitical importance. iran with has about 2.18 percent of total world reserves, the largest in the world. but couldn't played important role in the natural gas geopolitics and even it hasn't in b...

There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...

Hydrogen production through steam reforming of ethanol was investigated with conventional supported nickel catalysts and a Ni-containing smectite-derived catalyst. The former is initially active, but significant catalyst deactivation occurs during the reaction due to carbon deposition. Side reactions of the decomposition of CO and CH4 are the main reason for the catalyst deactivation, and these...
