Layered double hydroxides: Novel nanocatalysts for combustion of gaseous toluene from polluted air

The catalytic performance of Ni-Al, Mg-Al, and Co-Ni LDHs as novel nanocatalysts was evaluated in the oxidation of toluene. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The XRD and FTIR approved the structure and functional groups of the LDH, respectively. Also, the presence of cations with dif...

Hazardous Air Pollutant Emissions from the External Combustion of Hydrocarbon Gaseous Fuels Can Be Predicted!

Passage of the 1990Amendments to the Clean Air Act made it clear that maximum available control technology (“MACT”) regulations on the emission of hazardous air pollutants (“HAPS”) from process heaters and industrial boilers, used extensively in the petroleum and petrochemical industries, would be promulgated under congressional mandate by the U. S. Environmental Protection Agency in the year 2...

Combustion Studies on Paraffin Wax in Gaseous Oxygen and Nitrous Oxide

A series of static hybrid rocket firings were done in a laboratory scale motor using paraffin wax fuel with gaseous oxygen and nitrous oxide oxidizers. A five element swirl injector was used to inject the oxidizer at the head end of the motor. A pyrotechnic igniter was used to initiate the combustion. The combustion of fuel grain was carried out for a fixed duration and at different oxidizer in...

Characterization of Polycyclic Aromatic Hydrocarbon Particulate and Gaseous Emissions from Polystyrene Combustion

The partitioning of polycyclic aromatic hydrocarbons (PAHs) between the particulate and gaseous phases resulting from the combustion of polystyrene was studied. A vertical tubular flow furnace was used to incinerate polystyrene spheres (100-300 μm) at different combustion temperatures (800-1200 °C) to determine the effect of temperature and polystyrene feed size on the particulate and gaseous e...
