The present study examined the effect of three methods of preparation on the properties and catalytic performance of Cu-Mn/SiO2 catalysts for the water gas shift reaction (WGSR). Impregnation and coprecipitation and the new approach of thermal decomposition of [Cu(H2O)6][Mn(dipic)2].2H2O/SiO2 inorganic precursor complex were used for the synthesis of the silica-supported copper-manganese mixed ...

In the work the thermal behaviour of the magnetic nanoparticles modi ed with polysaccharide dextran of di erent weight ratios to the magnetite Fe3O4 was investigated using thermoanalytical methods di erential scanning calorimetry and thermogravimetric analysis. The adsorption of dextran on the magnetic nanoparticles was con rmed and the in uence of the dextran amount in the modi ed magnetic uid...

Many thermal runaway incidents have been caused by organic peroxides due to the peroxy group, -O-O-, which is essentially unstable and active. Lauroyl peroxide (LPO) is also sensitive to thermal sources and is incompatible with many materials, such as acids, bases, metals, and ions. From the thermal decomposition reaction of various concentrations of nitric acid (HNO3) (from lower to higher con...

Low-speed marine diesel flue gas denitrification is in great demand in the ship transport industry. This research proposes an ammonia supply system which can be used for flue gas denitrification of low-speed marine diesel. In this proposed ammonia supply system, ammonium bicarbonate is selected as the ammonia carrier to produce ammonia and carbon dioxide by thermal decomposition. The diesel eng...

The application of the mass spectrometer to the study of the thermal decomposition of polymers is described. The relationships between the structure of polymers and yield of monomers on decomposition are discussed. A quantitative treatment relating the compositions of certain coploymers and the yields of monomers is given. Data are presented showing the composition of the volatile hydrocarbons ...
