Hydrogen production from decalin dehydrogenation over Pt-Ni/C bimetallic catalysts

Hydrogen production from methanol decomposition over Pt/Al2O3 and ceria promoted Pt/Al2O3 catalysts

We present the activities and selectivities of Pt/Al2O3-based catalysts in the production of hydrogen from methanol through catalytic decomposition. For the decomposition reaction, the Pt and Pd catalysts promoted by ceria exhibit similar activity reaching 100% conversion at 315 C. Promoting with ceria had a positive effect on activity and selectivity. Among all catalysts, the 9% Pt– 10% CeO2/A...

Desorption of Furfural from Bimetallic Pt-Fe Oxides/Alumina Catalysts

In this work, the desorption of furfural, which is a competitive intermediate during the production of biofuel and valuable aromatic compounds, was studied using pure alumina, as well as alumina impregnated with iron and platinum oxides both individually and in combination, using thermogravimetric analysis (TGA). The bimetallic sample exhibited the lowest desorption percentage for furfural. Hig...

Neopentane Reactions over Bimetallic Pt-Sn/AI203 and Pt-Au/SiO2 Catalysts

The reaction of 2,2-dimethylpropane (neopentane) with hydrogen was studied over two series of supported bimetallic catalysts containing platinum as the primary group VIII metal and either gold or tin as the second metallic component. In both catalyst series the platinum nominal loading was maintained constant at 1 wt%. The loading of the second metal component was varied. An effort has been mad...

Reforming and oxidative dehydrogenation of ethane with CO2 as a soft oxidant over bimetallic catalysts

Kinetic modeling of pure hydrogen production from decalin

We investigate the dehydrogenation of decalin for the production of pure hydrogen for fuel cell applications. Supported Pt catalysts can achieve about 98% conversion with >99.9% selectivity for the dehydrogenation reaction. Cracking reactions occur only at high temperature. The partially dehydrogenated product, tetralin, was formed with a molar selectivity <6%, depending on the operating condit...
