Research ArticleOpen accessIn the abstractSynthesis and Characterization of Cobalt, Iron and Ruthenium Catalysts for the Production of Synthetic DieselDayna M. Ortiz Rodríguez, María del C. Cotto-Maldonado, José Duconge Hernández et al.Fossil fuels are currently the world's leading source of energy. Environmental legislations, the high price of fossil fuels, the concern about the supply of these fuels and technological development, makes it necessary to search for alternative sources of energy. The production of clean liquid fuels, such as synthetic diesel from synthesis gas, by Fischer-Tropsch (FT) method, is considered a very … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractAir Quality Measurement at the Solid Waste Disposal of Matuail Landfill Site at Dhaka, BangladeshMd. Faruque Hossain, ASM Maksud Kamal, Abdul Halim Farhad Sikder, Zakia ParveenAn investigation was conducted to assess the air quality impact and possible health risk of solid waste disposal on surrounding environment of Matuail landfill site in Dhaka city. Three different locations were selected for soil and plant samples. Leachate samples were collected from active dumping area and fish samples from treated leachate pond. Seven different locations were selected for air … …American Journal of Environmental Sciences, Vol. 15, Issue 5 · 31 Oct 2019 · 8,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Air Quality with Potential Linkage to the Metrological Conditions in Three Major Cities of PakistanNaima Hamid, Muhammad Junaid, Syeda Maria Ali et al.Environmental pollution being fatal for all living organisms is growing adversely due to excessive industrialization and urbanization. Vehicular emissions have aggravated the situation and pose detrimental effects on human health. In this study, the trend of ambient air quality was analyzed in the three metropolitan cities of Pakistan, including Karachi, Lahore and Islamabad for a period of three years (2008-2010). … …American Journal of Environmental Sciences, Vol. 15, Issue 2 · 11 Mar 2019 · 8,857 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoft Sensors for Monitoring Combustion Quality and Flue Gas Emissions in Power Station BoilersNallamilli P G Bhavani, Kesavan Sujatha, Ponmagal RajendranThis research work includes a combination of Fisher’s Linear Discriminant (FLD) analysis by merging Radial Basis Function (RBF) Network and Back Propagation Algorithm (BPA) for monitoring the combustion conditions of a coal fired boiler. The CCD Camera is used to capture the two dimensional flame images. The features such as images, average intensity, area, brightness and orientation etc., of the … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 7 Feb 2018 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on CRDI System Assisted Diesel Engine Fulled by Diesel with NanotubesC. Syed Aalam, C.G. Saravanan, M. KannanThis paper reports on the use of carbon multiwalled nanotubes as additive to the diesel fuel and the effects of their operational characteristics and performance, emission and combustion characteristics of the CRDI system assisted diesel engine. In this study, the tested fuels were prepared by dispersing carbon multiwalled nanotubes into the diesel fuel at the mass fraction of 25 and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 17 Jun 2015 · 7,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of E100 to Fuel a Used 4-Stroke MotorcycleT. SuthisripokProblem statement: Though ethanol and gasohol are proved to be used as alternative fuels in vehicles, 4-stoke motorcycles used nationwide mainly consumed gasoline 91/95. Approach: The motorcycle tested, the used Honda Wave125 model, was properly tuned at the rich relative air-fuel ratio (λ) 0.85, which theoretically gave the maximum power output. For the use of E100, the engine required richer … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 23 Feb 2012 · 9,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmission and Combustion Characteristics of Si Engine Working Under Gasoline Blended with Ethanol Oxygenated Organic CompoundsDhanapal Balaji, Periyasamy Govindarajan, Jayaraj VenkatesanProblem statement: The objective of this study is to investigate the effect of using unleaded gasoline and additives blends on Spark Ignition engine (SI engine) combustion and exhaust emission. Approach: A four stroke, single cylinder SI engine was used for conducting this study. Exhaust emissions were analysed for Carbon Monoxide (CO), Hydrocarbon (HC) and Oxides of Nitrogen (NOx) and carbon … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,141 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting and Time Series Analysis of Air Pollutants in Several Area of MalaysiaMohd Zamri Ibrahim, Roziah Zailan, Marzuki Ismail, Muhd Safiih LolaProblem statement: In keeping abreast with Malaysia’s rapid economic development and to meet the nation's aspiration for an improved quality of life, clean-air legislation limiting industrial and automobile emissions was adopted in 1978. Approach: Yet, to this day, air pollution from both sources still poses a problem for the nation. In order to predict the status of future air quality … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Contribution of Traffic to Air Pollution in the State of KuwaitN. Al-Mutairi, P. KoushkiProblem statement: The reduction in ambient air pollution is a universal goal-particularly in urban areas, the lack of resources often necessitates identification and prioritization of sources of air pollutants.
