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 ...

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, ...

First discernments for NO storage and reduction on lithium cuprate at moderate temperatures
Heriberto Pfeiffer works at the Instituto de Investigaciones en Materiales from the Universidad Nacional Autónoma de México at Mexico city. His research interests are focused on different topics as: i) the CO2 capture and catalytic conversion to added product values; ii) the sorption and reduction/oxidation of other acid polluted compounds (CO and NOx); iii) the hydrogen production ...

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 ...

Sources and technology for hydrogen production: a review
A comprehensive review of various processes and possible sources of hydrogen production are discussed in this paper. The various process for hydrogen production reviewed includes industrial process i.e. steam reforming, thermal cracking, partial oxidation of fossil fuels, coal gasification, electrolysis, thermochemical etc. and new emerging processes like photolysis, photo-voltaic electrolysis, ...

Sensitivity analysis in a simulated auto thermal Natural Gas reforming process
Auto Thermal natural gas Reforming (ATR) is one of the mostly used conventional hydrogen generation technologies by the highly developed countries. ATR reactors do not need any direct or indirect heat exchanger, and that is why they are more compact and so preferable than the other reformers. In this study, a process including reformers, carbon dioxide sequestration and a cryogenic separation ...

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 ...

Ultrasonic Assisted Oxidative Desulfurization Equipment and General Process
Diesel as a petroleum refinery products, in the fuel structure of countries have a higher share, has become an important power fuel, with the accelerated development of the world economy and the increase of diesel-fueled vehicles, the future demand for diesel will gradually increase, but the exhaust of diesel combustion on the environment is also increasingly serious harm. Given the wide ...

Petrochemical Manufacturer Breakthroughs Will Mean Less Plastic Goes to Waste
Many waste items provide important value before being tossed into a bin. Discarded plastic products, for example, originally serve as packaging to keep school lunches fresh, lightweight bottles for efficiently transporting fresh water to hard-to-reach areas, containers for soaps and detergents that facilitate hygiene – and much more. But what if that initial purpose was just the ...

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 ...
