Isha Srivastav, Mtech ,Thermal Engineering RTU Mr.Harimohan Sharma Mtech Coordinator ,AIET Sitapura affliated toRTU Sourabh Khandelwal Assistant Professor,AIET Sitapura Prof.Vikas Bansal RTU Kota ABSTRACT- Alternative energy resources need to be developed in order to meet the increasing demand for thefossil fuels.Furthermore from environmental perspective,these new sources of energy must be environmental friendly. Biomass and particularly vegetable oils ,fulfill these imperatives and is seen as potential substitute for mineral diesel .Base catalysed transesterification is most acceptable process for biodiesel production.In this research paper,we prepared biodiesel from Canola oil by transesterification process using methanol and KOH.The experimental investi- gation was made to check the constituent of biodiesel. Gas chromatography technique is employed to check the component of biodiesel.By this technique canola methyl ester is found in biodiesel sample.After that we calculate the performance characteristics ofCanolaBiodiesel with Diesel in air cooled engine. Brake thermal efficiency, Brake specific fuel consumption and Brake mean effective pressure are to be calculated experimentally. Keywords:Canola methyl ester,transesterification Volume VIII Issue XI NOVEMBER 2019 Page No : 448 Science, Technology and Development ISSN : 0950-0707 INTRODUCTION- The enhanced use of diesel fuel and the strict emission norms for the protection of environment have necessitated finding sustainable alternative and relatively green fuels for compression ignition engines. This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuels published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from algae by a chemical process called transesterification. Biodiesel is also called methyl or ethyl ester of the corresponding feed stocks from which it has been produced. Biodiesel is completely miscible with diesel oil, thus allowing the use of blends of mineral diesel and biodiesel in any percentage. Presently, biodiesel is blended with mineral diesel and used commercially as fuel in many countries. Biodiesel fueled CI engines perform more or less in the same way as that fueled with the mineral diesel. Exhaust emissions are significantly improved due the use of biodiesel or blends of biodiesel and mineral diesel. The oxides of nitrogen are found to be greater in exhaust in case of biodiesel compared to mineral diesel. But the higher viscosity of biodiesel also enhances the lubricating property. Biodiesel being an oxygenated fuel improves combustion.

In this study, oil was extracted from the seed by conventional soxhlet extraction with n-hexane and ultrasonication technique. Seeds without wing were found to contain about 15% oil for 6 hours soxhlet extraction at 50°C and 45 minutes ultrasonication at 40°C. Fatty acid composition of the soxhlet extracted oil analyzed by GC-FID showed stearic acid and oleic acid as the major components. Acid value, iodine value, saponification value, peroxide value, refractive index, viscosity were also determined. Thermogravimetric analysis of the oil for the determination of the thermal stability of the oil. Transesterification and Saponification process were carried out to produce Biodiesel and the soap from the extracted seed oil. The produced biodiesel and the soap were characterized and a comparative studies were carried out with international standards. The optimum yield for biodiesel was found around 40% of the raw materials and the cytotoxic analysis of the produced soap were carried out. The integrated production of biodiesel and soap from Sal seed oil will bring a drastic change in the realization fuel and cosmetic industries.

  • Von Hagen•Annotated+Index
    Introduction This annotated bibliography is intended for researchers, managers, policymakers, and industry participants concerned with development and conservation of non- timber forest products in the Pacific Northwest. Citations are followed by brief abstracts that highlight key themes as well as research methods, the location of the research or analysis, and the implications for management of nontimber forest products in the Pacific Northwest. Keywords at the end of each annotation are organized in an index that references species (both common and scientific name), geographic location, and key themes, topics, and organizations. The Pacific Northwest Research Station is also making this annotated bibliography available on diskette. The regional literature on nontimber forest products is fairly limited, although it has expanded considerably in the last 5 years. Much of the regional literature, espe- cially that addressing management and policy options, remains, however, in the realm of “gray” literature: unpublished manuscripts, discussion papers, proceedings of meetings, and agency memos. Given the wealth of information and perspectives, we have chosen to include regional gray literature in this bibliography. We also have drawn heavily on global lessons of nontimber forest product manage- ment, particularly from the Amazon basin, where nontimber forest product devel- opment has been attempted as a conservation mechanism, and from Scandinavia, where substantial government efforts have been directed towards catalyzing berry and mushroom collecting and bough production for rural development purposes. We have been hampered in our search of global examples by language barriers, access to publications, and time. In particular, a further exploration of the literature in Japanese, Russian, and Polish is warranted.
