    Efecto de la concentración y el tipo de biorregulador en la calidad qdel caite del piñón blanco (jatropha curcas L) para la producción de biodiesel en la región San Martín

    Biofuel is a clean fuel affordable, sustainable and reliable, available locally, which is obtain ned from renewable sources. Biomass fractions that have been used and are still enjoying renewed attention as a feedstock far the production of liquid biofuels from agriculture, such as lipids (oils and fats), simple sugars and polysaccharides sources.Biodiesel include alkyl esters (methyl, ethyl or propyl) obtained by chemical reaction of fat y acids from renewable plant or animal origin, with an alcohol. Biodiesel is an alternative fuel, clean combustion, the fassil diesel. Chemically, biodiesel comprises alkyl esters instead of alkanes and aromatic hydrocarbons of petroleum diesel.Today the white gear (Jatropha curcas) has pleasantly surprised the researchers from several countries, not only because of their agronomic characteristics, such as drought resistance and growth even in poor soil, or its ability to adapt effortlessly in tropical and semitropical areas, especially far its high oil content (50-55%) and protein (25-30%). Biodiesel can be obtained from the oil contained in the seeds of Jatropha curcas by transesterification.In this thesis work was evaluated the effect of two bio-regulators (Enzinom and Wuxal Baro), applied at three different levels (O ce I Ha, 1500 ce I Ha and 2000 ce I Ha) on the physical and chemical Jatropha seeds and its oil, which are important in the production of biodiesel. The bio-regulators were applied in two stages, the first at the beginning of flowering and the second fifty percent of flowering.Subsequently, the seeds of physic nut were pressed with a mechanical press actuated by ahydraulic jack, the oil obtained after filtration was subjected to various analyzes.The best time to harvest was determined by analyzes in the seed as the total fat content, which reached 50.43% value in the state of maturity.In the oil obtained from seeds when ripe pinion, analyzes yielded the fallowing results:-Acid, oil 1.14 mg KOH I g.- Peroxide, 2.03 02 I kg.- lodine, 98. 77 g iodine / 100 mi.- lndex kinematic viscosity, 40.43 cSt.Also, we evaluated the specific gravity and density, sulfated ash and specific residues.Finally, we determined that the best time to harvest Jatropha curcas is when you are in a mature state, because of better features and better quality oil far biodiesel production.
