“…The addition of Rh to spc-Ni/ MgAl catalyst restricted the deactivation of the catalyst due to the carbon formation in steam reforming of LPG and also renders long-term stability to the catalyst under tested conditions. It was found [9] that addition of Rh metal to the spc-Ni/MgAl catalyst had a promoting effect by inhibiting the sintering of Ni metal particles under tested conditions. 0.3 wt%Rh spc-Ni/MgAl catalyst showed the strong restraint of carbon formation compared to 0.3 wt%Ru spcNi/MgAl catalyst.…”

“…Steam reforming of hydrocarbons, especially of methane, is the largest and generally the most economical way to make hydrogen and has been reported by many researchers [6,[9][10][11]. Steam reforming gives the highest quantity of hydrogen in the product stream, but the requirements of considerable heat input, high catalyst loadings and large reactors are necessary.…”

Hydrogen has been attracting great interest as a major energy source in near future. The lack of an infrastructure has led to a research effort to develop fuel processing technology for production of hydrogen. In this review, we are reporting the catalytic reforming of gaseous hydrocarbons carried out in our research group, covering dry-reforming of CH 4 , tri-reforming of CH 4 , the electrocatalytic reforming of CH 4 by CO 2 in the SOFC (solid oxide fuel cell) system and steam reforming of LPG. Especially, we have focused on our work, though the related work from other researchers is also discussed wherever necessary. It was found that tri-reforming of CH 4 over NiO-YSZ-CeO 2 catalyst was more desirable than dry-reforming of CH 4 due to higher reforming activity and less carbon formation. The synthesis gas produced by trireforming of CH 4 can be used for the production of dimethyl ether, Fischer-Tropsch synthesis fuels and high valued chemicals. To improve the problem of deactivation of catalyst due to carbon formation in the dry reforming of CH 4, the internal reforming of CH 4 by CO 2 in SOFC system with NiO-YSZ-CeO 2 anode catalyst was suggested for cogeneration of a syngas and electricity. It was found that Rh-spc-Ni/MgAl catalyst showed long term stability for 1,100 h in the steam reforming of LPG under the tested conditions. The addition of Rh to spc-Ni/MgAl catalyst restricted the deactivation of catalyst due to carbon formation in the steam reforming of LPG and diesel under the tested conditions. The result suggested that the developed reforming catalysts can be used in the reforming process of CH 4 , LNG and LPG for application to hydrogen station and fuel processor system.

“…2.13 ). Kim et al 136 also observed that loading of about 0.3 wt % Rh on NiMgAl mixed oxide catalysts derived from hydrotalcite precursors improved the catalytic activity in the steam reforming of n -hexadecane. Added Rh acts as a promoter, reduces the carbon formation on the catalyst surface, and prevents Ni metal from sintering.…”

Biodiesel's contribution as a renewable energy carrier is increasing continuously. Fuel cell market penetration, although slow, is now an irreversible reality. The combination of solid oxide fuel cells (SOFC) with biodiesel offers considerable advantages because it entails both high energy conversion efficiency and nearzero atmospheric carbon emissions.This work is aimed at proving the efficiency of a newly-developed (patent pending), Al 2 O 3 /YSZ-supported NiAl 2 O 4 spinel catalyst to steam reform biodiesel. Reforming converts biodiesel into a gaseous mixture, mainly composed of H 2 and CO, used directly as SOFC fuel.The work is performed in a test rig comprising a lab-scale, fixed-bed isothermal reactor and a product-conditioning train. The biodiesel/water mixtures are emulsified prior to their spray injection in the reactor preheating zone, where they are instantaneously vaporized and rapidly brought to the desired reaction temperature to avoid thermal cracking. Reforming takes place at gas hourly space velocities equal to or higher than those in industrial reforming units. The products are analysed by at-line gas chromatography.The results show that biodiesel conversion is complete at steady state. Thermodynamic calculations reveal that the fast reforming reaction reaches chemical equilibrium. The catalyst's performance is very efficient and prevents carbon formation and deactivation.
