N-butane partial oxidation to maleic anhydride under transient regimes
Maleic anhydride (MA) is commercially produced from partial oxidation of n-butane by air over vanadium pyrophosphate (VPP) catalyst. There has been a huge research interest to better understand the different aspects of this industrially attractive reaction including mechanism, dynamic catalyst phase evolutions as well as the effect of redox operating conditions such as gas/solid residence time, ...

Preparation and characterization of nickel based catalysts for partial oxidation of methane
Hydrogen, which can be used in many fields without polluting the environment, is thought to be the cleanest fuel source of 21th century. Therefore, low cost production, facile storage and transportation of hydrogen are important research subjects that are investigated by many universities and related commercial facilities. Steam-hydrocarbon reforming is the major hydrogen production process ...

Co-production of synthesis gas and power by integration of Partial Oxidation reactor, gas turbine and air separation unit
A new synthesis gas production process based on partial oxidation (POX) of natural gas is investigated. Synthesis gas and mechanical power are generated in a plant that integrates a POX reactor, a synthesis gas turbine and an air separation unit. The synthesis gas is expanded in the turbine which runs the air separation unit. By means of an exergy analysis, it is shown that the synthesis gas ...

Comparative study of steam injection effects on operation of gas turbine cycles
In the present work, gas turbine cycles are modified with steam injection between the combustion chamber exit and the gas turbine inlet. Heat recovery steam generators, utilising the exhaust gases, provide these cycles with the injected steam at saturated vapour. The irreversibility of the different composing units of the cycles and the variation of gas properties owing to steam injection as well ...

What is TPO and Why is it Performed?
Temperature programmed oxidation (TPO) is an analytical technique capable of establishing the oxidation of an element or compound through thermal excitation, with various applications in the field of catalysis. The performance of TPO requires a furnace or microreactor capable of increasing temperatures of a catalyst in precise increments up to extreme conditions, for example in brackets of ...

Nanoporous Pt
n+–CeOxcatalyst films grown on carbon substratesDeposition of the Pt doped cerium oxide catalyst layers on carbon nanotubes and flat carbon substrates by magnetron sputtering leads to growth of solid solution films composed of nanorods oriented perpendicularly to the substrate surface forming fractal like highly porous structure. The films contain only cationic Pt2+ and Pt4+. Cerium oxide is partially reduced. The catalyst films reveal high ...

Cleaning Up Gasification Syngas
Documento sin título Introduction By definition, gasification is the art of changing a non-gaseous substance, such as a liquid or a solid, into a gas. By this definition, processes such as combustion, anaerobic digestion and pyrolysis would be classified as gasification. However, in today’s world, gasification is defined as any process, which produces a “synthesis gas” or a ...
