“…Biodiesel has several advantages over petroleum-derived diesel: it is biodegradable, non-toxic, sulfur-free, aromatic-free and can be produced from a number of renewable feedstocks, such as fresh [1][2][3][4][5] or waste [6,7] vegetable oils and animal fats [8,9]. Among oils, both edible (mostly from canola, soybean and palm [1][2]) and non-edible ones (Madhuca indica, Jatropha curcas, Jatropha gossypiifolia and Pongamia pinnata [3][4][5]) can be used to this end; although the latter are still not at a commercial stage, they are being more and more investigated, since they avoid the competition between food and fuel, and they are generally extracted from plants that can be cultivated in arid or marginal lands, which are unsuitable for conventional agriculture.…”

Abstract:The profitability of biodiesel is nowadays limited by the price of raw materials, which require high purity standards to be employed in conventional production processes. To overcome this problem, the transesterification of triglycerides in alcohol supercritical conditions could be conveniently used: the non-catalytic nature of this process allows the use of recycled raw materials, which are cheaper. To this end, a pilot scale plant for the continuous production of biodiesel in supercritical conditions was designed, manufactured and operated. In this research paper, rapeseed oil and bioethanol were used as raw materials, and the investigated temperatures were between 200 and 340°C, the pressure between 150 and 240 bar, and the alcohol-to-oil ratio ranged between 9 and 100. The best fatty acid ethyl ester (FAEE) yields were obtained at 340°C, 240 bar and a molar ratio of 42, which is line with easier-to-control lab-scale tests in batch conditions found in the literature. This encourages widening of the operating conditions to further improve the maximum achievable yields for the rapeseed oil-ethanol system.

“…Indeed, nowadays the oil cost is up to 80% of the total production cost of the biofuels. 1 On the other hand, the production costs could be dramatically decreased using low-grade raw material, such as: acid stocks produced during physical neutralization of fats and oils; domestic or industrial sludge; poultry, porcine or cattle slaughterhouse wastes; 1 algae bioreactors; 16 or nonedible oils, such as from palm-trees 17 or jatropha 18 species. Besides, these low cost fatty materials would address the so called trilemma food/energy/environmental, which has recently being discussed in important publications.…”

O desenvolvimento de um processo ou produto industrial envolve diferentes passos: (i) identificar a necessidade de um novo produto ou processo; (ii) pesquisar no laboratório, em escala de vidraria, um caminho que leve ao produto ou processo desejado; (iii) construir uma planta piloto em escala de laboratório; (iv) scale up uma ou mais vezes a planta piloto; (v) construir e iniciar a produção industrial. Do início de 2002 até o fim de 2011, o Laboratório de Materiais e Combustíveis (Instituto de Química, Universidade de Brasília) dedicou-se ao desenvolvimento de um processo alternativo para produzir biodiesel. O objetivo deste trabalho é descrever todo este desenvolvimento, a fim de mostrar o longo caminho para se construir uma planta piloto em escala de laboratório.The development of an industrial process or product involves different steps: (i) identify the necessity of a new product or process; (ii) research in glassware scale to find a way that leads to the desired product or process; (iii) build up and optimize a laboratory pilot plant; (iv) scale up one or more times the pilot plant; (v) build up an industrial plant and start up a commercial production. From the beginning of 2002 to the end of 2011, the Laboratory of Materials and Fuels (Institute of Chemistry, University of Brasília) has focused in the development of an alternative process to produce biodiesel. The aim of this account paper is to describe all this development in order to show the long way to achieve a laboratory pilot plant scale.

“…However, we had made preliminary measurements (reported earlier) for the Jatropha oil at BNL and had recorded a number of around 12. One published paper [11] has numbers of 17.32 and 8.45 for two genus of Jatropha. In any case, it would seem that Jatropha oil's acid number is similar to or less than that of residual oil and hence might encourage the idea that the blends might not be any more and may even be less 'corrosive' than straight residual oil.…”
