The surface tension is one of the main properties for characterization quality fuel atomization process its use in a diesel engine. There lack published information about values vegetable oils. aim this research to obtain mathematical model based on physical that establishes relationship between tensions different oils and their fatty acid composition. For reason, from literature reports, experimental data related was collected. Knowing as function temperature, total amount 15 feedstocks at...
The production of biodiesel from fatty acid distillates (FAD) is a technically viable route but the assessment engine performance and environmental impact are non-well researched issues. scope this contribution to develop characterization FAD obtained as waste product vegetable oil refining industry evaluate exhaust emissions on diesel engine. A physicochemical also developed. gas chromatography results show acids profile, indicating 50.56% linoleic acid. Acidity level indicated that must be...
The scope of this paper is to analyze the possibility and feasibility use emulsification method applied waste cooking oils fatty acid distillates as diesel engine fuels, compared with other commonly used methods. These products are obtained from refining oil industry, food industry service sector, mainly. They rarely feedstock produce biofuels things, in spite constitute a potential source environmental contamination. From review state arts, significant decreases exhaust emissions nitrogen...
The aim of this research is to identify and quantify the categories which have largest environmental impact in biodiesel production process from Jatropha curcas L oil. selected due its availability Cuba, so 400 L/d was defined as a functional unit. valorization analysis conducted taking into account conventional oil production. based on several factors such use synthetic fertilizers, pesticides, agriculture wastes. activities industrial stages are shown. Life Cycle Assessment addressed...
The excessive blooming of green filamentous macroalgae is a global problem due to their unwanted presence in freshwater, lakes, nursery garden and stagnant waters. An attractive solution use as biofuel feedstock. In this work, the studied was Chaetomorpha cf. gracilis. oil extraction accomplished using Soxhlet method obtaining yield 1.85%. gas chromatography analysis showed higher unsaturated fatty acids (56.14%) compared saturated (35.18%), highlighting content oleic acid, 27.89%. kinematic...
Data on the rapid, elemental and calorimetric analysis, such as ash melting behaviour thermogravimetric profiles of six Cuban biomass feedstock are shown, in order to assess their potential for bioenergy production. The studied biomasses Jatropha curcas husk, Moringa oleifera Dichrostachys cinerea, Ulva lactuca, Chaetomorpha gracilis Sargassum fluitants. Seed, kernels or stems algae were characterized by weight. Sample preparation tests established according referenced German standards with...
Data in this paper covers in-cylinder pressure and volume, crank angle degrees as time magnitude, first derivate of pressure, admission injection a diesel engine fuelled with biodiesel. This data brings additional information such ignition delay rate heat released. As condensed information, some graphs were obtained are into the database vs. CAD, CAD ROHR CAD. The shows measurements cylinder behaviour biodiesel from two different sources, which both interest bioenergy industry at local scenarios (
In this paper, the assessment of puffing and micro-explosion occurrence in emulsion drops with differentwater percentage is studied. The emulsified fuels are formulated using micro channel emulsifier, rapeseedoil diesel fuel as continuous phase, well water Sorbitan Sesquioleate surfactant. Theformulated dispersed systems covered under different experimental factors such ratio andsurfactant percentage. reported all tested (i.e. andwithout surfactant). A sudden highest number noted when...
