Comparison of Carbonyls and BTEX Emissions from a Light Duty Vehicle Fuelled with Gasoline and Ethanol-Gasoline Blend, and Operated without 3-Way Catalytic Converter [PDF]
Mehran University Research Journal of Engineering and Technology, 2011 This paper presents the comparison of unregulated emissions such as carbonyls and BTEX (Benzene, Toluene, Ethyl Benzene, and Xylenes) species emanated from a light duty SI (Spark Ignition) vehicle E-0 (fuelled on gasoline) and E-10 (ethanol-gasoline ...

CO2 emissions and soil carbon mineralisation under different systems
Agro@mbiente On-line, 2019 Usage and management alter the dynamics of soil organic carbon (SOC). The aim of this study was to compare the CO2 emissions in a Typic Humudept under different uses, and to relate the effects of CO2 emissions to the organic carbon content of the soil ...

Observation of J = 1 -> 0 emission from H15NC [PDF]
Monthly Notices of the Royal Astronomical Society, 1977 Emission from the J = 1-0 transition of H(N-15)C has been detected in the direction of DR21(OH). The transition frequency of 88,865.69 MHz was measured in the laboratory by microwave absorption spectroscopy. The computed N-15/C-13 isotopic abundance ratio of 1.01 for DR21(OH) is larger than those calculated from isotopes of HCN in other interstellar ...

Mitigation of CO2 emissions by hydrotalcites of Mg3Al-CO3 at 0 °C and high pressure
Applied Clay Science, 2021 This work shows the maximum CO2 capture capacity, using CO2 isotherms at 0, 20 and 30 °C and pressures of up to 35 atm, of four adsorbents with different particle size distribution and different pore size distribution: two hydrotalcites of Mg3Al-CO3, one synthesized in laboratory (C1) and another commercial (C2) and two calcined (C1 500 and C2 500 ...
