“…This means that the formation of carbon residue from marine fuel RMA could be as high as 50 times that of biodiesel. The much lower carbon residue from biodiesel is attributed to the FAME in its composition, which contains much less ash, fewer impurities and almost no aromatic compounds [26]. The higher level of oxygen in biodiesel compared with marine fuel also leads to more complete burning and much less carbon residue formation after the burning process.…”

Biodiesel produced from vegetable oils, animal fats and algae oil is a renewable, environmentally friendly and clean alternative fuel that reduces pollutants and greenhouse gas emissions in marine applications. This study investigates the influence of biodiesel blend on the characteristics of residual and distillate marine fuels. Adequate correlation equations are applied to calculate the fuel properties of the blended marine fuels with biodiesel. Residual marine fuel RMA has inferior fuel characteristics compared with distillate marine fuel DMA and biodiesel. The flash point of marine fuel RMA could be increased by 20% if blended with 20 vol% biodiesel. The sulfur content of residual marine fuel could meet the requirement of the 2008 MARPOL Annex VI Amendment by blending it with 23.0 vol% biodiesel. In addition, the kinematic viscosity of residual marine fuel could be reduced by 12.9% and the carbon residue by 23.6% if 20 vol% and 25 vol% biodiesel are used, respectively. Residual marine fuel blended with 20 vol% biodiesel decreases its lower heating value by 1.9%. Moreover, the fuel properties of residual marine fuel are found to improve more significantly with biodiesel blending than those of distillate marine fuel.

Abstract. In this paper, the behavior of different types of biodiesel (from rapeseed, soybean, coconut and palm oils) in contact with different parts of a common rail injection system was evaluated. Stability tests were carried out by static immersion of test pieces in biodiesel at two different temperatures, 50ºC and 75ºC. After 15 days of immersion, interaction between pieces and biodiesel was evaluated considering two parameters: mass variation of pieces and biodiesel acid value (AV). A mass loss in both injector and pipes was found, no matter which biodiesel was used. In case soybean oil biodiesel was used, a slightly lower loss was achieved. On the other hand, coconut oil biodiesel showed a significant acid value increase with respect to the others. The temperature increase influenced mass loss and acid value increase.

“…There are only few examples in the literature involving optimization of transesterification of vegetable oils to produce biodiesel, even knowing that the costs of biofuel production are high (Domingos et al, 2008). Pinzi et al (2011) evaluated together with the process variables, how raw material fatty acid composition affects the biodiesel production. The authors applied a factorial design to determine how the operation conditions affected the transesterification process (reaction temperature, initial catalyst concentration by oil mass and methanol concentration), while the reaction yield was considered as the response variable.…”

“…Optimum Pinzi et al (2011) Another optimization study used Raphanus sativus (L. Var) crude oil in ethanolysis with sodium hydroxide as catalyst. Three process variables were used to develop the experimental design: the ethanol:oil molar ratio (MR of 6:1 and 12:1), the catalyst concentration in relation to oil mass (C of 0.4 and 0.8 wt% NaOH) and the alcoholysis temperature (T of 45 and 65 o C).…”
