Estudo Prospectivo Sobre Processo De Extração De Material Graxo De Resíduos Agroindustriais Com Produção Simultânea De Biodiesel

Abstract

RESUMOO biodiesel é um biocombustível importante para a matriz energética nacional é produzido de diferentes fontes oleaginosas, desempenhando papel importante na produção final do biocombustível. Diante de sua cadeia produtiva e da importância de métodos mais sustentáveis, realizou-se um estudo prospectivo sobre o processo simultâneo de produção de biodiesel visando à condensação das etapas de produção via simultaneidade de extração e respectiva conversão a partir de resíduos agroindustriais oleaginosos. Além disso, tem-se como objeto de estudo a utilização de catálise heterogênea ao sistema, agregando facilidades na separação do produto e do meio catalítico. Neste nicho de pesquisa e desenvolvimento de métodos alternativos para o setor do biodiesel encontram-se poucas patentes e artigos, sendo em sua maioria evidenciados processos em escala laboratorial. Sendo assim, tal tecnologia merece atenção, investimento e desenvolvimento para seu escalonamento, tendo em vista agregar diversos benefícios ao setor, desde a matéria-prima até o processo e distribuição.Palavras-chave: Biodiesel.

PROSPECTIVE STUDY ON THE PROCESS OF EXTRACTION OF AGRICULTURAL WASTE GRAIN MATERIAL WITH SIMULTANEOUS BIODIESEL PRODUCTION ABSTRACTBiodiesel is an important biofuel for the national energy matrix is produced from different oil sources, playing an important role in the final production of biofuel. In view of its production chain and the importance of more sustainable methods, a prospective study was carried out on the simultaneous production process of biodiesel, aiming at the condensation of the production stages through the simultaneity of extraction and respective conversion from agro-industrial oleaginous residues. In addition, the object of study is the use of heterogeneous catalysis to the system, adding facilities in the separation of the product and the catalytic medium. In this niche of research and development of alternative methods for the biodiesel sector are few patents and articles, being mostly evidenced processes in laboratory scale. Therefore, such technology deserves attention, investment and development for its scheduling, aiming to add several benefits to the sector, from the raw material to the process and distribution.

Extraction and Characterization of Pequi Seed Oil for Biodiesel Production: A Green Management of Waste to Biofuel Using Ethanol and Heterogeneous Catalysis

“…Resuming the main differences, also advantages, between the two systems presented are less reactors in the simultaneous extraction/production process, no need of extracting/pre-treating the oil from the raw material previously, reusing of the solvent that will play two roles in the process (extraction and reagent) and also the capacity of reusing the heterogeneous catalyst (one of the most important and significant possibilities for this type of catalyst) promoting the environmental friendly focus of the proposed system. 59 Figure 6 presents the results of the reactions using the proposed system in Figure 5. As it was explained, the ratio between ethanol and pequi's oil had to be adjusted to this new system, that way a mass ratio of 1 to 16.6 of pequi seeds and ethanol, respectively, was used (the ratio was estimated by the minimum volume of ethanol necessary to be recovered and still have enough to continues both reaction steps at the same time).…”
