Low Pressure Catalytic Combustion of Hydrogen on Palladium

Low Pressure Catalytic Combustion of Hydrogen on Palladium

Exhausts of airship fabric bag in the stratosphere such as hydrogen which can be used for fuels by using catalytic combustion method. This can save the extra fuels used in the power system. Pd/γAl2O3 catalyst was prepared in this work by impregnation method and the H2 catalytic combustion reaction kinetic was investigated between the pressure of 3.6 kPa and 101.3 kPa. The effects of temperature...

Synthesis of nanostructured palladium, palladium oxide and palladium-palladium oxide nanocomposite by the gel combustion method and application as catalyst of hydrogen release

This paper presents a new gel combustion method to synthesize palladium nanoparticles, palladium oxide (PdO) nanoparticles and palladium-palladium oxide nanocomposites. In the proposed method, there are some effective parameters including palladium chloride concentration, polyvinyl alcohol (PVA) concentration, acid concentration, solvent composition and combustion temperature that their values ...

Catalytic Combustion of Biogas-Hydrogen Mixtures in a Packed Bed Reactor

Catalytic Combustion of Methane

Catalytic combustion is an environmentally benign technology which has recently reached the stage of commercialization. Palladium is the catalyst of choice when considering gas turbines fuelled with natural gas because of its superior activity for methane oxidation. Several fundamental issues are still open and their understanding would result in an improvement of the technology. Hence, the wor...

Catalytic Combustion of Syngas

The catalytic combustion of syngas/air mixtures over Pt has been investigated numerically in a channel-flow configuration using 2D steady and transient computer codes with detailed hetero-/homogeneous chemistry, transport, and heat transfer mechanisms in the solid. Simulations were carried out for syngas compositions with varying H2 and CO contents, pressures of 1 to 15 bar, and linear velociti...
