the technology related to the production of bio fuels could change in the coming years thanks to algae. now the use of biofuels has been known and well developed and it can be inside volvo xc60 diesel for sale. But, according to theories that "there is no limit to the best ", there are several studies underway to optimize their use in industrial and transport contexts (upstream of biofuel production), and for increase its production efficiency (downstream), through different technologies and different substrates. In this latter regard, biofuels are often and conveniently classified in the first generation and second generation . The first are those obtained from well-known crops, widely used and used for food purposes ( rapeseed, soy, sunflower, palm, corn, wheat, beet and sugar cane) . The latter, however, are not yet significantly present on the market and are produced from substrates, generally not usable for food purposes (lignocellulosic materials, inedible oils, agro-food waste).
Production Of Biofuels
For some years, however, we have also started talking about third generation biofuels , that is, those obtained from the cultivation and processing of algae and / or microalgae . This process dates back to World War II in Germany, and has subsequently been studied predominantly in the United States and Japan and Korea. The most interesting characteristics of this type of substrate for the production of biofuels are: algae cultivation, algae pool, Close-Up Engineering. Productivity Algae have a higher lipid content which is associated with higher productivity per unit area. Non-competitiveness with respect to the food market. In recent years there has been a noticeable intensification of traditional crops for conversion to biofuels (bioethanol first of all) causing an unsustainable increase in the costs of raw materials and a significant impact due to the conversion of forests and grasslands into crops for energy. Although they remain CO 2 sinks , these could cause various environmental, economic and social impacts. Use of otherwise non-productive land . The cultivation of algae could take place in environments that cannot be used in any other way, including the sea which represents more than 70% of the earth's surface. This point is fundamental because it is functional to the sustainability of production understood in the most general and complete way possible. Use of different qualities of water . The cultivation of algae lends itself to different aquifer environments such as fresh and salt water but also urban and zootechnical waste, reducing its environmental impact and exploiting what would otherwise be waste to be treated. Optimal compatibility with the existing infrastructure of transport fuels.
Production And Industrial Processes
In fact, biofuels obtained from the processing of microalgae have the same chemical and physical properties ( Lower Calorific Value ) than bio fuels from crops grown on land. Combined production of energy and fertilizers. Like any organic compound, even algae, after any processing for energy purposes, lend themselves to the production of biofertilizers with high nutritional value. Furthermore, their cultivation has further economic benefits since it can be used for human and animal nutrition. Containment of carbon dioxide emissions. Algae, like any other biomass, are characterized by the so-called zero CO 2 emission cycle , since they release into the atmosphere - during their combustion - the same amount of CO 2 absorbed during their life for biochemical processes. Integration into other production and industrial processes. A volvo xc60 diesel price payer need to know, Additional benefits in terms of energy efficiency and environmental impact can be achieved through the integration between algae cultivation and, for example, water treatment plants and / or intensive farming. In area of renewable energies, the biofuels chain offers now undeniable advantages that have pushed the EU decisively to stimulate its diffusion starting from 2003. Below is a summary of the strengths of this agro-industrial chain by dividing the environmental, agro-environmental, technical-applicative and socio-economic benefits.
Viscosity And Density
Environmental aspects i.e.complete renewability of the resource; biodegradability of the product; positive balance of C (greenhouse effect reduction); positive balance of energy entering and leaving the supply chain system; better quality of emissions from engines fueled with biodiesel (i.e. lower presence of benzene, alkibenzene, sulfur dioxide, CO, heavy metals). Agro-environmental aspects: diversification of agricultural production (increase in biodiversity); enhancement of "difficult" environments thanks to the use of species suitable for non-food production; knowledge of the cultivation techniques of the main oil species destined for trans-esterification; Technical-application aspects: no alteration of the characteristics of the diesel engines (torque, power, specific consumption, maintenance times) using the biodiesel in the mix. with diesel fuel; no alteration of boiler operation using pure oil or pure biodiesel; possibility of using the oil as it is also in high-speed diesels by means of equipment capable of modifying its viscosity and density directly on the vehicle; possibility of using the oil as it is in slow diesel engines or in boilers for the production of electricity. Socio-economic aspects: stable outlet for nonfood products on the commodities market; reduction of surplus food problems in the Community agricultural system; affirmation of the fundamental role of agriculture in the protection of the territory through its multifunctionality; creation of new jobs; increase in tax revenues deriving from the taxation of agricultural and / or industrial activities generated by the supply chain; greater protection of the health of the population (lower toxicity of biodiesel than diesel); well-known and optimized production technologies; existing product distribution network.
