MicroAlgae Fuel is the 4th generation of the future and oil giants are racing to develop this biofuel

    Hello, algae are photosynthetic organisms that can grow in water and generate energy from carbon dioxide and sunlight. There are two types of algae commonly found: macroalgae and microalgae. There are various materials to make piun from corn to palm oil, but agar is very interesting because it grows fast and produces a lot of fuel. Algal biomass contains three major components: carbohydrates, proteins and lipids or natural oils. Most natural microalgal oils are in the form of tricyclic glycerol, which is the correct type of oil for PSI biofuels.

    Besides microalgae biofuel, it can be used to provide energy in other ways. Some species of algae can produce hydrogen gas under certain growth conditions, but cultured microalgae typically double every 24 hours during the growth phase. Some microalgae peaks double every 3½ hours, and the oil content of microalgae is typically 20-50%, but can reach 80% in some strains. For this reason, microalgae have attracted the interest of several global oil companies, such as Exxon, who have developed two microalgae culture systems currently in use: the open pond system and the closed pond photobioreactor. I'm here. Cultivation of microalgae. In this system, the shallow ponds are typically around 30 cm deep and the algae grow under conditions similar to their natural environment.

    The pond is designed in a static configuration, with water wheels ensuring circulation and mixing of algal cells and nutrients. Officially, it can be made out of concrete or simply dug into the ground and covered with plastic so the ground doesn't absorb the liquid. This system is often operated in continuous mode. H. Fresh feed containing nutrients, nitrogen, phosphorus and mineral salts was fed, and closed photobioreactors were used to overcome the problems of contamination and evaporation.

    These systems, compared to open ponds, are made of transparent materials and are usually placed outdoors and illuminated by natural light. Culture vessels have a large surface area to volume ratio Teaching light direction Solar tubes are typically less than 10 cm in diameter to maximize sunlight penetration.

    The broth medium is circulated via a pump to a pipe where it is exposed to light for the photosynthetic process and returned to the biomass reservoir. Algal sedimentation is prevented after growing in open ponds or photobioreactors by maintaining highly turbulent flow within the reactor using either mechanical or water-lift pumps. Microalgal biomass must be harvested for further processing. Commonly used harvesting methods are graffiti or centrifugal systems.The oil from the biomass is removed by solvent extraction and further processed into biodiesel.

    In recent years, research groups at universities and corporate groups have developed new methods to increase the efficiency of processing algae into oils and pharmaceuticals. Gebyar's work and microalgae development involves either increasing the oil content of existing strains or choosing new routes with higher oil content. B. Plastic Spirulina and Omega 3 in Indonesia have such a hot season and a very long coastline, unlike countries with four seasons, they can use a very large scale microalgae development system. Unfortunately, microalgae research is still very limited, and efficient extraction techniques have been adopted by various Lex development campuses and foreign companies.

    Some test results show that oil yields from algae still cannot beat petroleum on price, but with product diversification, microalgae can produce products other than biofuels, It can produce large amounts of essential supplemental omega-3 fatty acids. Algae are a very good source of vitamins, minerals and proteins, and seeds such as chlorella and spirulina are commonly consumed for health.Other useful products that can be made from algae are phosphorus It is a bioplastic made from fuel il and takes a very long time to decompose, so it is very unfriendly to the environment.Bioplastic from algae can be produced with low CO2 emissions, or Even by absorbing the emissions of these products, they can be key to the development of algal biofiles.In addition to producing petroleum, they also produce a variety of high-value derivatives.

    Large-scale algae culture is possible if you do it seriously. The world's largest algae culture facility is a deadly legend in Western Australia, where 740 hectares of algae ponds are used to produce beta-carotene supplements and biofuels. Meanwhile, the U.S. federal government is supporting various large-scale algae projects, and of course there are plans to expand Energy Sapphire in the water-rich state of New Mexico, Indonesia. have to explore.
