Uses and Benefits of Biodiesel
#1
Biodiesel is a liquid fuel produced from vegetable oil or used oil and grease. Most transportation fuels are liquids, because vehicles usually require high energy density, as occurs in liquids and solids. Biodiesel burns very purely and resembles a standard diesel. It is derived from the oil that is produced from sunflower, soybean or rapeseed oil using methanol and a catalyst. Chemically, it is the mixture of methyl esters of fatty acids. This fuel is a renewable resource because It regenerates at the same speed as being spent. This fuel has a bit lower energy content, but it contains a higher percentage of oxygen which helps it to combust better.

Conventional diesel engines use fuel with 20 percent biodiesel without difficulty, and many of the new engines can also use pure biodiesel. Biofuels do not require the production of a new car or a new car engine, they already have a huge advantage over hydrogen technology which is still at the beginning of the development. In 2010, worldwide biofuel production reached 105 billion liters.

This compatibility with existing engines has prompted many countries to turn to biofuels, confident that they will thus be able to reduce the cost of fossil fuels. The European Union has set itself the goal to use 6 percent of biodiesel by 2010, which will mean a five-fold increase in growing plants that produce ethanol.

The Advantages of Biodiesel Compared to Diesel

Technical aspects:
• Provides better ignition and lubricity which means greater engine efficiency and duration
• Safer handling and storage: flash point of about 150 ° C - fossil diesel about 70 ° C
• Requires no modifications to the engines
• It is not necessary to change transport and storage systems in order to use biodiesel
Ecological aspects:
• Reduced emissions of greenhouse gases, particulates and aromatics: CO2, CO, SO2, NO2, soot, benzene, toluene
• Nontoxic
• Biodegradable
Energetic aspects:
• Renewable basic raw materials and the use of already used cooking oils and fats
• Reduces the need to import oil and the risk of supply
Economic aspects:
At the macroeconomic level, the development of biodiesel production affects the following indicators:
• Employment
• The increase in industrial production
• Additionally increasing funds to agriculture
• Contribution to the economic development of rural areas
• The increase in foreign exchange reserves
• Reducing energy parameters depending on external factors.

Why Biodiesel?

• The need for increased security in the supply of liquid fuel for the transport sector and agriculture using renewable sources;
• The need to be used in diesel engines that don’t pollute the environment and at the same time does not require modifications to the engine and can be blended with fossil diesel;
• Provides users with reliable fuel at a lower price.
• Reduced emissions (especially CO2) that participate in greenhouse gas emissions and their impact on global climate;
• By ratifying the Kyoto Protocol, the EU committed itself to reduce total emissions by 8% by 2012 compared with the level of the year 1990
• EU member states must ensure that the minimum proportion of biodiesel and other renewable fuels is in its markets;
Reference value of the goals set according to Directive 2003/30/EC (calculated based on the total energy content of gasoline and diesel fuel): 2% by 31st December 2005, 5.75% by 31st December 2010, and the European Commission determines further progress.

Selling Equipment for Biodiesel

The innovation is based on a flexible and modular mobile transesterification technology, which allows the conversion of restaurant waste oils and fats to get quality refined oils and fats according to standard EN 14214. Built-in modular units are also necessary for evaporation and distillation of methanol, which enables effective and maximum use of unreacted methanol.

Second-generation biofuels are produced from sustainable feedstock. Sustainability of a feedstock is defined, among others, by availability of the feedstock, and impact on biodiversity and land use. Many second-generation biofuels are under development such as Cellulosic ethanol, Algae fuel, biohydrogen, biomethanol, DMF, BioDME, Fischer-Tropsch diesel, biohydrogen diesel, mixed alcohols and wood diesel.

The problem of energy deficiency is raising in all industrial and economical fields, ant threatens to impact industrial, science and technology progress. Biodiesel is considered a very advanced technology achievement which has the potential to change human life in the sense of overcoming the world energy problem.
