Elaboración de biodiesel a nivel laboratorio utilizando aceites vegetales refinados-aceites vegetales usados y estudio teórico planta de producción
(Universidad de Chile, 2015)
Existen variados estudios sobre biocombustibles, como alternativa a los combustibles
fósiles, dentro de los cuales encontramos el uso de aceites vegetales y aceites usados
para el desarrollo de biodiesel. Si bien existen algunas experiencias a nivel...
There are several studies on biofuels, as an alternative to fossil fuels, among which we find the use of vegetable oils and used oils for the development of biodiesel. Although there are some experiences at the national level, this practice is not widespread or incorporated in the country. In this seminar, the use of refined vegetable oil was analyzed as a raw material for biodiesel, and it was compared with the use of recycled frying oils (cooking-fast food). For this, the technical and economic capacity for the production of this fuel was analyzed, for a subsequent incorporation of the technique used (basic transesterification) in the installation of a medium-sized biodiesel production plant. The results show that the refined vegetable oil presented the best performance...

Estimación de la huella de carbono y energía neta de especies oleaginosas con potencial energético cultivables en Chile
(Universidad de Chile, 2014)
dependiente de los combustibles fósiles, y los escenarios de volatilidad de sus
actuales precios, lo sitúan en una situación desfavorable. Por lo que ha apostado potenciar la
incorporación de biocombustibles hasta un equivalente al 10% de los combustibles...
Fossil fuels combustion are the main source of energy of man, the principal responsible of atmosphere carbon stocks the increase and global warming. This situation and the current world energy crisis encourage countries to innovate their energy generation systems preferring energy sources that are sustainable in time with generation process with a lower environmental impact. Chilean production systems depends on fossil fuels, however, the current volatility prices scenario put the country at a disadvantage in the international context. For this reason, the government of Chile has decided to enhance the incorporation of biofuels into the energy matrix to an equivalent of 10% of the fuel consumption of land motor vehicles by 2020. The present study analyzed the carbon footprint and net energy of the agronomic or forestry production system of oilseed crops with energy potential such as guindilla (Guindilia trinvervis), higuerilla (Ricinus communis), jatropha (Jatropha curcas), jojoba (Simmondsia chinensis) and moringa (Moringa oleífera). The analysis was based on a life cycle analysis (ISO 14.040) inventory made for all the activities involved in the agronomic or forestry process of each specie. Carbon footprint was estimated according the PAS 2050 standard usually used to estimate carbon footprint of goods and services. The energy balance (net energy) was based on various proposals and studies about energy flux on agronomic or forestry crops. The higher carbonfootprint value corresponds to jojoba culturing (19,4 Ton CO2-e) because his cultural practices considers a 9 years period of management to ensure a stabilized fruit/seed production. Conversely, the lower emissions corresponds to the guindilla management (15,9 TonCO2-e), because his life cycle last less than a year. Jojoba culturing shows the higher net energy value (379.863,1 MJ * ha-1) of all the crops analized because is capable of generate a considerable quantity of fruits and, in turn, seeds once his production is stabilized contributing to the crop energy output. The lower net energy value corresponds to guindilla production system (850,2 MJ * ha-1), because of their low fruit production results in low energy output. The analyzed crops has biofuels production potential as an energy alternative because the relation between the energy used in the field (input energy) and the energy obtained of the harvest (output energy) its higher than zero. The use of these crops in national industry may contribute to reduce greenhouse gases emissions because the carbon dioxide resulting for its use its part of natural carbon dioxide cycle on the earth (biogenic carbon)....
