Reforming of methane

Steam reforming of CH is commonly carried out at 750 to 900°C, thus at the lower operating temperature of MCFCs a high activity catalyst is required. The internal reforming of methane in IRMCFCs, where the steam-reforming reaction... 

Methane. The largest use of methane is for synthesis gas, a mixture of hydrogen and carbon monoxide. Synthesis gas, in turn, is the primary feed for the production of ammonia (qv) and methanol (qv). Synthesis gas is produced by steam reforming of methane over a nickel catalyst. 

One can only admire the insight of the first researchers who used Ni as the active electrode material in the Ni/YSZ cermet anodes In addition to being a good electrocatalyst for the charge transfer reaction (3.8), Ni is also an excellent catalyst for the steam or C02-reforming of methane ...

Discuss the importance of the steam-reforming process for the production of hydrogen and synthesis gas. Is this process endothermic or exothermic What is the rate-limiting step for the steam reforming of methane ... 

Carbon dioxide reforming of methane to produce synthesis gas, i.e, a mixture of carbon monoxide and hydrogen (COj+CH, ZCO ZHj, = 261 0 kJ/mol) has attracted substantial... 

In a number of publications, Rostrup-Nielsen discusses different mechanism of methane steam reforming over Ni catalysts [17]. The proposed simplified reaction sequence for reforming of methane is as follows ... 

Figure 2.14 depicts the thermodynamic equilibrium data related to C02 reforming of methane at atmospheric pressure. It is noteworthy that at temperatures below 800°C, elemental...
