[en] ASPECTS OF ELECTRICITY GENERATION IN BRAZIL, USING BIODIESEL AS FUEL / [pt] ESTUDO DA UTILIZAÇÃO DO BIODIESEL PARA GERAÇÃO DE ENERGIA ELÉTRICA NO BRASIL

FELIPE CARNEIRO DA CUNHA TORRES 14 March 2007 (has links)
[pt] Com a assinatura da Lei 11.097 de 13 de Janeiro de 2005, o Biodiesel fica introduzido na matriz energética brasileira. Até o fim de 2007, a mistura deste biocombustível ao diesel mineral, derivado do petróleo, é voluntária pelas distribuidoras de combustíveis. A partir de Janeiro de 2008, todo o óleo diesel será comercializado obrigatoriamente com 2% de Biodiesel misturado e, a partir de 2013 a mistura deverá conter 5% de Biodiesel. O mercado potencial de Biodiesel para esta meta de 2008 é de aproximadamente 800 mil toneladas anuais. Revela-se, portanto, um enorme esforço de todas as esferas interessadas neste mercado: instituições de ensino e pesquisa, agro-indústrias, indústrias ligadas ao setor energético, entre outras, com objetivo de se atingir a meta estipulada pela Lei. Como parte deste esforço, no presente trabalho foram levantados aspectos técnicos, econômicos, sociais e ambientais sobre a implementação do programa de implementação do Biodiesel na matriz energética brasileira, visando identificar os prós e contras da utilização deste biocombustível. Um modelo de análise termodinâmica de uma usina termelétrica foi desenvolvido para descrever o comportamento de motores ciclo diesel de grande porte operando com 4 tipos diferentes de Óleo Combustível e 5 tipos de Biodiesel. / [en] With the Federal Act number 11.097, from January 13, 2005, Biodiesel is introduced in the Brazilian energy matrix. To the end of 2007, a voluntary mixture of this fuel to mineral diesel oil can be prepared by fuel distributors. From January 2008, diesel oil will have to be commercialized with 2% of Biodiesel. This percentage is to be increased to 5% by 2013. The goal for 2008 means, approximately, 800 thousand ton of Biodiesel annually. All parts involved, universities, research institutes, agro business and energy industries, among others, have been putting a great deal of effort to meet the target set by Federal Government. The present work is a small contribution to this effort. Technical, economical, social and environmental aspects of the problem have been taking into account in the present study, in order to identify pros and cons of the utilization of Biodiesel. A simple thermodynamic model of a thermal-electric power plant was developed to predict the behavior of a large capacity diesel engine operating with conventional fuel (four different types of fuel oil) and with Biodiesel.
