Investigation of Blended Palm Biodiesel-Diesel Fuel Properties with Water Emulsification

چکیده مقاله:
Under the crisis of global warming and drastic climate changing, carbon-neutral renewable energy is considerably proposed as a feasible clean alternative energy to fractionally replace fossilized fuel. To cop up with ever stringent emission regulations, researchers have investigated different types of renewable fuels like biodiesel and water emulsion. The fuel physical characteristics are among the most important parameter to determine the quality of each fuel before it being tested in the engine. This study aims to evaluate the stability period and mean droplet size of the particles and to characterize the physicochemical properties of emulsified biodiesel blend B20 in terms of kinematic viscosity, density and calorific value with different percentage of water; 5%, 10%, 20%, and 30%. The tested fuel samples were compared with diesel fuel and blended palm biodiesel (B20). The experimental results show that when the proportion of water was increased in diesel-biodiesel blends, the dispersed water droplets become larger. The stability period in terms of days for emulsion fuels becomes lower when the amount of water was increased to the blends. The least stability period for emulsion obtained by emulsion with 20% and 30% water content which is 2 days. The kinematic viscosity and density of biodiesel emulsions were larger than those of the neat biodiesel. The calorific value for emulsion with 5% water content is comparable to blended fuel and conventional diesel even though there was a slight reduction

Fuel properties of loofah (Luffa cylindrica L.) biofuel blended with diesel
Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...

Biodiesel Production from Chicken Fat Using Nano-calcium Oxide Catalyst and Improving the Fuel Properties via Blending with Diesel
In this research, biodiesel was produced using chicken fat in the presence of calcium oxide nano-catalyst. To do so, the effect of various parameters like temperature, reaction time, catalyst amount and methanol to oil ratio was investigated on the biodiesel production. The results showed that the best conditions for biodiesel production were obtained such as the temperature of 65oC, methanol t...

Biodiesel as an Alternative Fuel for Diesel Engines
There is growing interest in biodiesel (fatty acid methyl ester or FAME) because of the similarity in its properties when compared to those of diesel fuels. Diesel engines operated on biodiesel have lower emissions of carbon monoxide, unburned hydrocarbons, particulate matter, and air toxics than when operated on petroleum-based diesel fuel. Production of fatty acid methyl ester (FAME) from rap...
