(MENAFN- Gulf Times) A research team from the Gas Processing Centre (GPC) at Qatar University College of Engineering (QU-CENG) has synthesised new nanocatalysts and improved existing ones via modern preparation techniques.
The team used bulk and surface sensitive analytical tools to fully characterise the nanocatalysts. Catalysts are materials employed to reduce the energy required for chemical reactions and accelerate their speed.
Catalysts do not consume during reactions and stay with full activity for several years. This project aims to obtain zero emission of unburned natural gas from engines fuelled with natural gas, according to a statement by QU.
'It is worth mentioning here that the greenhouse effect of methane (main component of natural gas) is more than 20 times worse than that of carbon dioxide, GPC research professor Dr Mahmoud Khader said.
He added, 'We have synthesised a novel nanocatalyst via an economical, one-step preparative methodology called ‘Solution Combustion Synthesis' (SCS).
'The new SCS methane oxidation catalyst is made of a solid solution mixture of palladium oxide and ceric oxide supported on aluminium oxide. The catalyst can oxidise an extremely small amount of natural gas in the exhaust of any engine and, therefore, reduce natural gas emission.
Dr Khader noted that steam reforming is the reaction between methane and water vapour to produce hydrogen (and carbon monoxide as well as carbon dioxide). He said, 'SRM is the main source for industrial hydrogen generation. The present invention will solve some problems associated with the existing industrial methane steam reforming catalysts.
'This reaction aims to produce synthesis gas (syngas, hydrogen and carbon monoxide mixture). The DRM is the reaction between carbon dioxide and methane. The resulting syngas can be a useful raw material for various petrochemical processes such as Fischer-Tropsch synthesis and for the production of useful products, for example, ammonia, urea and methanol.
'We developed a novel nickel-based nanocatalyst, which showed to be resistant and stable for the CO2 reformation of methane.
