One of probably the most discussed alternative fuel sources in the past few years has been algae biofuels. With the world-wide efforts to attempt to cut down on our reliance on fossil fuels Cristiano Ronaldo Jersey , algal biofuels have been showing potential on being able to scale to the quantities of production to inexpensively replace our dependence on traditional oil sources.
Beyond the benefits of currently being renewable, algal biofuels have also shown that they’re considerably much better for the environment through the reduced quantities of Carbon Dioxide released at the time of their use. Bio-diesel from algae is one of the alternative fuel sources currently being explored for potential widespread usage. To comprehend this we must first answer the question of what is bio-fuel?
What Makes Up Biofuel?
Biofuels could be in various forms to including liquid, gas, or solid materials. This source are generally made from any biological carbon-based substances, with corn and soy beans being the most popular crops utilized for biodiesel manufacturing. Utilizing these crops needs the land normally used to grow food that we eat. As a result Sergio Ramos Jersey , the renewable fuels business has been investing time and effort into refining the method to extract biofuel from algal mass as a third generation biofuel.
Algae Biodiesel Benefits
Algae will develop at 50 to a hundred times faster than corn or soy, and don’t need freshwater or farm land to be developed. Algae may be grown in non potable water or suspended containers located exactly where the land can not be used to grow food. The conventional barriers to successful use of algae as a biodiesel have been the relative low expense of oil when compared to the cost of extracting the biofuel from algae, however, with enhanced technology and increased crude oil costs this distance has decreased over the past couple of years.
When developed in closed photo bioreactor systems, the algae growth process can be controlled resulting in greater yields and improve biodiesel production. Another advantage with the algae development method is the algae pulls carbon dioxide from the air and replaces it with clean oxygen. This makes bio-diesel algae farms a lot more attractive to place near industrial plants that produce extreme amounts of carbon dioxide to help decrease pollution but also benefit the algae grower.
Biodiesel algae has the potential to replace all crude oil world-wide. If algae farms can live up to their potential Real Madrid Jersey , then this could be completed 100 million acres in contrast it would take exponentially much more land to accomplish the same effect with conventional biofuel crops.
How Is Oil Extracted from Algae?
Extracting the oil from algae biomass has been the major expense barrier for the growth of algae biodiesel into the industry. Once the algae are harvested, the oils are then extracted through the algae cells. The most rudimentary method to do this is to use an oil press which is similar to how an palm oil press functions. The oil press has roughly a 75 % extraction rate. Another method used to extract the oil is the hexane solvent extraction. This method results in approximately a 95 percent extraction rate of the oil from the algae.
The third technique employed is the super-critical fluids approach which can get up to 100 percent of the oil out of the algae. In this approach, carbon dioxide is used to act as the super-critical fluid. The algal biomass is pressurized and heated to alter it into a fluid and gaseous state. Then, the carbon dioxide is mixed with the algae which turns it almost entirely into oil. This method needs a significant investment in equipment and incurs considerable expense. Once the algae oil is extracted, it is then refined utilizing the transesterification method where sodium hydroxide is mixed with methanol to produce biofuel from algae biomass.
