Research ArticleOpen accessIn the abstractCombustion, Performance and Emission Characteristics of Diesel Engine with Neem Oil Methyl Ester and its Diesel BlendsL. Prabhu, S. Sathish Kumar, M. Prabhahar, K. RajanBiodiesel, an alternative fuel is derived from the fats of animals and plants. As energy demands increase and fossil fuels are limited, research is directed towards alternative renewable fuels. The main advantages of using this alternative fuel are its renewability, biodegradability and better quality of exhaust gases. It is technically competitive and environmentally friendly alternative to conventional petro-diesel fuel for … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhycoremediation and the Potential of Sustainable Algal Biofuel Production using WastewaterAdel A. Fathi, Mohamed M. Azooz, Mohamed A. Al-FredanWastewater remediation by microalgae is an eco-friendly process with no secondary pollution as long as the biomass produced is reused and allows efficient nutrient recycling. This study was undertaken to evaluate the remediation of wastewater by the green alga Chlorella vulgaris and the potential of these alga (biomass) to produce sustainable biofuel. The results shows that the cultivation of green … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 27 Feb 2013 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Wheat Straw Varieties Cultivated Under Different Climatic and Soil Conditions in Three ContinentsYaning Zhang, A. E. Ghaly, Bingxi LiOver 500 million tonnes of wheat straw are produced annually worldwide, the majority of which are burnt in the field causing significant environmental and health problems as well as serious traffic accidents in addition to loss of a valuable resource. Wheat straw is abundantly available and renewable and can be used as an energy source in gasification and combustion systems. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 26 Jun 2012 · 21,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Corn ResiduesYaning Zhang, A. E. Ghaly, Bingxi LiCorn residues (cobs, leaves and stalks) are abundantly available renewable materials that can be used as an energy source in gasification and combustion systems. Proper understanding of the physical properties of these materials is necessary for their use in thermochemical conversion processes. The physical properties (moisture content, particle size, bulk density and porosity) of corn cobs, leaves and stalks were … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 19,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Nitrogen on Growth and Lipid Content of Chlorella pyrenoidosaSubhasha Nigam, Monika Prakash Rai, Rupali SharmaProblem Statement: In today’s scenario, microalgae are widely recognized as a promising source for biofuel production as a renewable source of energy. They are exceedingly rich in oil, which can be converted to biofuel. This paper deals with one of the method to enhance the lipid content in microalgae. Approach: Microalga, Chlorella pyrenoidosa, was grown autotrophically in batch culture and … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 12,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransesterification of Palm Oil for the Production of BiodieselKhalizani Khalid, Khalisanni KhalidProblem statement: Palm oil is known as an important source of edible oil with significant values of renewable energy. Depletion of petroleum had captured much attention on producing biodiesel from the palm oil. Approach: The most concerning methods for the production of biodiesel were discussed, namely transesterification (alkali and acid), enzymetic approach and supercritical alcohol. Results: The results showed the … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 8,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Total Solid Contents on Biogas Yield from Cattle Manure Using Rumen Fluid InoculumBudiyono, I. N. Widiasa, S. Johari, SunarsoProblem statement: Anaerobic digestion was a biological method used to convert organic wastes into biogas and a stable product for land application without adverse environmental effects. The biogas produced could be used as an alternative renewable energy source. The aim of this study was to analyze the influence of total solid contents on biogas yield from cattle manure using fluid … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 12,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractPromotion of Coconut Shell Gasification by Steam Reforming on Nickel-DolomitePattaraporn Chaiprasert, Tharapong VitidsantBiomass gasification by the use of metallic nickel as active metal on dolomite support has been chosen as catalyst because of its activity in biomass steam gasification and tar reduction. The purpose of this study is to study the effects of critical parameters on product gas compositions such as temperature, steam to carbon ratio (S/C) and oxygen input. The results … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 8,410 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Development in Biological Process for Wastewater Treatment to Produce Renewable FuelKadhum M. Shabeeb, Khalid A. Sukkar, Rana A. Azeez et al.Problem statement: Hydrogen is a clean energy source. Bio-conversion of biomass to generate hydrogen has been achieved using anaerobic fermentation of some well-defined materials, in wastewater. No data available on hydrogen yielded from wastewater using inoculum extracted from Iraqi municipal wastewater treatment plant. Approach: This study investigated the effects of substrate concentration, initial pH and process temperature on biohydrogen production … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,252 accessesView PDFCite
