Use of crude filtered vegetable oil as a fuel in diesel engines state of the art: Literature review

Characteristics of vegetable oils for use as fuel in stationary diesel engines—Towards specifications for a standard in West Africa

“…They must be regularly aired to prevent acidification and heat build-up [13]. Batches are considered to be stabilized if their moisture content is below 9% in weight [38].…”

“…One of the most advantageous branches in the biofuel sector is seen to be the production of straight vegetable oil (SVO) for direct use as fuel in diesel engines. There has been renewed interest in this activity in recent years, for stationary applications in the fields of agriculture, power generation and industry [10][11][12][13][14][15]. These sectors are major consumers of fuel oils, either high distillates (diesel), medium distillates (DDO Distillate Diesel Oil) or heavy Fuel Oil 180 (FO180), which might be wholly or partially replaced with SVO [10,12,13].…”

This solution may contribute to reducing the cost of fossil fuel imports incurred by most developing countries, curb dependence on fossil fuels and limit greenhouse gas (GHG) emissions [14,[16][17][18].…”

“…In such a decentralized scheme, the processing conditions can be very different from one unit to another, leading to a wide range of oil qualities. Using vegetable oil of unknown quality as fuel might be risky and rapidly cause fatal mechanical damage to engines [13,14,28]. Consequently, oil quality is a recurring issue that is impeding the development of the sector, since there is no standard defining what should be the quality characteristics of vegetable oils for fuel purposes in stationary engines.…”

Triagem de métodos de purificação de óleos com acidez elevada para produção de biodiesel

“…Dentre os principais frutos que constituem fontes de óleo, incluem-se nozes, coco, dendê e azeitonas (SIDIBÉ et al, 2010). A Tabela 3.1 demonstra dezessete fontes de óleos vegetais estabelecidas e seus respectivos conteúdos percentuais de lipídeos.…”
