The emission characteristics of methyl ester of refined rice bran oil – diesel blend mixed in the proportion of 10:90, 20:80, 30:70, 50:50 and 10:0 (v/v) were studied. The emission of carbon monoxide, unburnt hydrocarbons, nitric oxide and nitrogen di oxide by different fuels at various load on 3.73 kW C.I. engine were compared with respect to diesel. The emission of carbon monoxide from the en...

The rapid development of China’ s economy and society is obtained at the cost consumption energy, especially fossil energy. And coal-based energy structure enables China to become largest carbon dioxide emitter in world. With enhancement global greenhouse effect, ecological environment deterioration becoming increasingly serious. Carbon emission reduction has one most important international is...

Manure application is effective in promoting soil carbon sequestration, but its impact on N2O emission is not well understood. A field experiment was conducted in a maize-cultivated black soil in Northeast China with six treatments: inorganic fertilizer (NPK), 75% inorganic fertilizer N plus 25% pig (PM1) or chicken (CM1) manure N, 50% inorganic fertilizer N plus 50% pig (PM2) or chicken (CM2) ...

The study investigates the effect of aluminium oxide nanoparticles as an additive to Madhuca Indica (mahua) methyl ester blends on performance, emission analysis of a single-cylinder direct injection diesel engine operated at a constant speed at different operating conditions. The test fuels are indicated as B10A0.2, B10A0.4, B20A0.2, B20A0.4 and diesel respectively. The results indica...

Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...

In this review we give an overview of the present status of research on carbon nanotube (CNT) field emitters and their applications. Several different construction principles of field-emission devices with CNTs are summarized. The emission mechanism is introduced and a detailed overview is given of the measured emission properties and related topics of CNT electron sources. We give also several...

Methane is the second most important greenhouse gas (GHG) after carbon dioxide. Amount of methane emission from energy sector is increasing day by day with various activities. In present work, various sources of methane emission from upstream, middle stream and downstream of oil & gas sectors are identified and categorised as per IPCC-2006 guidelines. Data were collected from various oil & gas ...

Vertically aligned carbon nanotube films with diameters smaller than 5 nm, high densities up to 10/cm, and lengths of ~ 5–8 Am were deposited by microwave plasma-assisted chemical vapor deposition. Experiments show that, by continuous reduction in the thickness of the iron film (i.e., ~0.3–0.5 nm), small diameter carbon nanotubes can be achieved with diameters that ranged from 1–5 nm, and the f...
