Methane reforming with carbon dioxide to synthesis gas over Mg-promoted Ni/HY catalyst... 

Methane reforming with carbon dioxide proceeds in a complex sequence of reaction steps involving the dissociative adsorption/reaction of methane and COj at metal sites. Hydrogen is generated during methane dissociation In the second set of reactions CO2 dissociates into CO and adsorbed oxygen. The reaction between the surface bound carbon (from methane dissociation) and the adsorbed oxygen (from CO2 dissociation ) yields carbon monoxide. A stable catalyst can only be achieved if the two sets of reactions are balanced.

Steam methane reforming with PSA for hydrogen production. 

An integrated proof-of-concept (POC) size fluidized-bed methane reformer with embedded palladium membrane modules for simultaneous hydrogen separation is being developed for demonstration (Tamhankar et al., 2007). The membrane modules will use two 6 in. X 11 in. Pd-alloy membrane foils, 25-pm thick, supported on a porous support. The developmental fluidized-bed reactor will house a total of five (5) membrane modules with a total membrane area of about 0.43 m2 and is scheduled for demonstration by September 2007. 

Besides the economic benefits, the PSA-based hydrogen plant has a number of technical advantages compared to traditional Steam Methane Reforming with solvent extraction and methanation. These advantages include172 ...

In Table 2, the nuclear electricity generation is now commercially conducted, and nuclear hydrogen production is now under research and development. As for the nuclear hydrocarbon production, a nuclear synthetic methane recycling process is being developed by the Tokyo Institute of Technology for on-board steam-methane reforming with calcium oxide for CO2 sorption (Ref. 5). 

Figure 3 Hydrogen by steam methane reforming with CO2 removal.

The CALCOR process is similar to a conventional steam methane reformer with an amine acid gas removal system, except that the CO2 from the amine system is recycled to the reformer furnace. The reformer operates at a very low pressure to reduce reforming severity. The synthesis gas from the CO2 removal system is just above atmospheric pressure. It is saturated with water and residual CO2 and must be compressed before entering downstream separation equipment. The process features a very low methane slip below 500 ppm in the synthesis gas [11].
