Fish oil containing energy is the energy content of the 90% diesel engine, and is easy to be refined into bio diesel, bio diesel extracted using fish oil combustion cleaning degree is high, can be used to reduce dependence on fossil diesel and improve air quality. In Iran, as a by-product of fish fish oil processing industry production is very big. Made of the offal fish oil raw materials mainly come from fish processing (the head, tail, fins, internal organs and skin).
In the world, the production of biodiesel, used as compost, formation of bio gas (methane) and burned directly to generate energy, is for fish offal of different utilization ways. The number of years in Iran fish culls the Persian Gulf region is about 300000 tons. The moisture content of fish products waste of about 65% or so. 53% of the fish product waste in the liquid phase state (a mixture of water, oil and suspended solids), can extract about 11% from fish product waste fish oil (using 7 kilograms of fish waste, can produce 3.71 kilograms of liquid phase, and extract 0.81 kg of fish oil from separating). Fish oil through chemical reaction process (methanol, potassium hydroxide and extracted from fish waste oil transesterification), eventually into biodiesel fuel. Per liter of fish oil can produce 0.9 liters of biodiesel. Biodiesel made no sulfur or may lead to air pollution material. In Iran, fish product waste as a sustainable source of biodiesel production, considerable potential. |
