The performance of rapeseed oil combustion in regard to organic pollutant production (solid particulate, light hydrocarbons, aldehydes and PAH) was investigated and compared to the performance of a typical heavy fuel oil burned in the same experimental conditions. C1-C6 hydrocarbons were formed in lower amounts in the rapeseed oil flame, but the composition and distribution was found to be very similar for both fuels. Due to the very high-temperature environment typical of stationary combustion a very low presence of aldehydes like acrolein was found only in the initial region of the rapeseed oil spray flame. Rapeseed oil was found to be a "cleaner" fuel compared to the heavy fuel oil also in respect to the formation of particulates, condensed species, and in particular PAH. The composition of PAH formed from the combustion of both fuels was that typically measured in rich combustion irrespective of the fuel utilised.

HYBRID CATALYTIC COMBUSTION OF METHANE/HYDROGEN MIXTURES
Cimino, S.; Allouis, Christophe Gerard; Mancino, G.; Nigro, R. (2014-05-01)
Hybrid catalytic combustion technology, which is a staged process comprising a preliminary catalytic partial oxidation (CPO) step followed by a homogeneous flame combustion with interstage heat removal, was tested for the first time with mixtures of methane and hydrogen. Short contact time CPO experiments were run to elucidate the effect of the progressive substitution of methane with H-2 in the fuel feed to the structured catalytic reactor, which was operated under self-sustained conditions at high tempera...
Heterpolyacid catalysts for etherification of isoolefins
Obalı, Zeynep; Doğu, Timur; Department of Chemical Engineering (2003)
Due to the water pollution problems created by MTBE, significant research was focused on the production of alternative oxygenates, such as ethyl tert-butyl ether (ETBE), tert-amyl-methyl-ether (TAME) and tert-amyl-ethyl-ether (TAEE) as octane enhancing gasoline blending components. These oxygenates are expected to improve the burning characteristics of gasoline and reduce exhaust emissions of CO and hydrocarbons. Generally, macroreticular acidic resin catalysts (Amberlyst-15) are used for the etherification...
Pyrolysis and Combustion Studies of Fossil Fuels by Thermal Analysis Methods Review
Kök, Mustafa Verşan (1995-02-01)
Instances where differential scanning calorimetry, thermogravimetry and differential thermal analysis have been applied to study the pyrolysis and combustion behaviour of fossil fuels (peat, lignite, bituminous coals, anthracite, oil shales, crude oils, lignite-oil mixtures, etc.) are reviewed. The literature survey showed that thermal methods were important not only theoretically but also from a practical point of view.

Liquid ethanol is widely used in practical fuels as a means to extend petroleum-derived resources or as a fuel additive to reduce emissions of carbon monoxide from spark ignition engines. Recent research has also suggested that ethanol and other oxygenates could be added to diesel fuel to reduce particulate emissions. In this cursory study, the combustion of small ethanol droplets in microgravity environments was observed to investigate diffusion flame characteristics at higher ambient pressures and at vari...
Thermal stability and SO2 resistance of Pd/Rh-perovskite based three-way catalyst wash-coated on cordierite monoliths
Bayram, Bilal; Önal, Işık; Külah, Görkem (2022-01-01)
The effect of hydrothermal aging and SO2 poisoning on the three-way catalytic performance of dispersed Pd/Rh-based and Pd/Rh perovskite-based catalysts were studied by using a dynamic activity test system that simulates redox fluctuations of gasoline engine exhaust conditions. Both catalysts were supported on ceria-zirconia-alumina and wash-coated on cordierite monoliths and were characterized by ICP-OES, BET, XRD, TEM-EDX, DRIFTS, and CO chemisorption. Their performance was very close when the catalysts we...
