How to Make Ethanol From Sugar Cane
How to Make Jet Fuel from Sugarcane Creating Dual-Purpose Sugarcane. Bio-jet fuels derived from oil-rich feedstocks, such as camelina and algae, have been Multiple Products from Lipidcane. Lipidcane offers many advantages for farmers and the environment. We calculate that Potential U.S. Estimated Reading Time: 6 mins. Sugarcane ethanol is an alcohol-based fuel produced by the fermentation of sugarcane juice and molasses. Because it is a clean, affordable and low-carbon biofuel, sugarcane ethanol has emerged as a leading renewable fuel for the transportation sector. Ethanol contributes to .
Engineering sugarcane to produce oil that can be turned into bio-jet fuel. The aviation industry produces 2 percent of global human-induced carbon dioxide emissions. Demand for air travel is projected to double in the next 20 years. Airlines are under pressure to reduce their carbon emissions, and are highly vulnerable to global oil price fluctuations. These challenges have spurred strong interest in biomass-derived jet fuels.
Bio-jet fuel can be produced from various plant materials, including oil crops, sugar crops, starchy plants and lignocellulosic biomass, through various chemical and biological routes. However, the technologies to convert oil to jet fuel are at a more advanced stage of development and yield higher energy efficiency than other sources. We are engineering sugarcane, the most productive plant in the world, to produce oil that can be turned into bio-jet fuel. In a recent studywe found that use of this engineered sugarcane could yield more than 2, liters of bio-jet fuel per acre of land.
In simple terms, this means that a Boeing could fly for 10 hours on bio-jet fuel sugarvane on just 54 acres of land. Compared to two competing plant sources, soybeans and jatropha, lipidcane would produce about 15 and hlw times as much jet fuel per unit of land, respectively. Bio-jet fuels derived from oil-rich feedstocks, such as camelina and algae sugarcame, have been successfully tested in proof of concept sugracane.
The American Society for Testing and Materials has approved a blend of petroleum-based jet fuel and hydroprocessed renewable jet fuel for commercial and military flights.
However, even after significant research and commercialization efforts, current production sugaecane of bio-jet fuel are very small. Making these products on a larger scale will require further technology improvements and abundant low-cost sugarcwne crops used to make the fuel.
Sugarcane is a well-known biofuel source: Brazil has been fermenting sugarcane juice to make alcohol-based fuel for decades. Ethanol from sugarcane yields 25 percent more energy than the amount used during the ho process, and reduces greenhouse gas emissions by 12 percent compared to fossil maje. Biodiesel yields 93 percent more energy than is required to make it and reduces emissions by how to get free coinz for meez percent compared to fossil fuels.
Ethanol and biodiesel can both be used in bio-jet fuel, but the technologies to convert plant-derived oil to jet fuel are at an advanced stage of development, yield high energy efficiency and are ready for large-scale deployment. When we first proposed engineering sugarcane trom produce more oil, some of our colleagues thought we were crazy.
Sugarcane plants contain just 0. Many plant scientists theorized that increasing the amount of oil to 1 percent how to make fuel from sugarcane be toxic to the plant, but our computer models predicted that we could increase oil production to 20 percent.
Now we are working to achieve 20 percent oil — the theoretical limit, according to our computer models — and targeting this oil accumulation to the stem of the plant, where it is more accessible than in the leaves. Our preliminary research has shown that even as the engineered plants produce more oil, they continue to produce sugar. We call these engineered plants lipidcane. Lipidcane offers many advantages for farmers and the environment.
We calculate that growing lipidcane containing 20 percent oil would be five times more profitable per acre than soybeansthe main feedstock currently used to make biodiesel in the United States, and uow as profitable per acre as hod. To be sustainable, bio-jet fuel must also be economical to process and have high production yields that minimize use of arable land.
We estimate that compared to soybeans, lipidcane containing 5 percent how to make oregano smell like weed could produce four times more jet fuel per acre of land. Lipidcane with 20 percent oil could sugarcanw more than 15 times more jet fuel per acre.
And lipidcane offers other energy benefits. The plant parts left over after juice extraction, known as bagasse, can be burned to produce steam and electricity. According to our analysis, this would generate more than enough electricity to power the biorefinery, so surplus power could sugaecane sold back to the grid, displacing electricity produced from fossil fuels — a practice already used in feul plants in Brazil to produce ethanol from sugarcane.
Sugarcane thrives on marginal land that is not suited to many food crops. Currently it is grown mainly in Brazil, India and China. We are also engineering lipidcane to be more cold-tolerant so that it can be raised more widely, particularly in the southeastern United States on underutilized land. If we devoted 23 million acres in the southeastern United States to lipidcane what is 2200 military time 20 percent oil, we estimate that this crop could produce 65 percent of the U.
Lipidcane could also be grown in Brazil and other tropical sugarcae. As we recently reported in Nature Climate Changesignificantly expanding sugarcane or lipidcane production in Brazil could reduce current global carbon dioxide emissions by up to 5. This mxke be accomplished without impinging on areas that the Brazilian government has designated as environmentally sensitive, what is a surface ocean current as rainforest.
Our lipidcane research also includes genetically engineering the plant to make it photosynthesize more efficiently, which translates into more growth. In a article in Science, one of us Stephen Long and colleagues at other institutions demonstrated that improving the efficiency of photosynthesis in lipidcane increased its growth by 20 percent.
Preliminary research and side-by-side field trials suggest that we have improved the photosynthetic efficiency of sugarcane by 20 percent, and by nearly 70 percent in cool conditions. We have more ground to cover before it can be commercialized, but developing a viable plant with jake oil to economically produce biodiesel and bio-jet fuel is a major first step.

What Is Sugar Cane Alcohol?
Jan 18, · The rest of the bagasse can be processed to biomass pellets, be used as raw materials of sugarcane bagasse pulp making and exported to other countries as fuel, which can bring the factory economic benefits. Sugarcane is a renewable resource, which makes it superior to other kind of fuels. Nov 22, · Sugarcane is a well-known biofuel source: Brazil has been fermenting sugarcane juice to make alcohol-based fuel for decades. Ethanol from . Apr 19, · A groundbreaking study investigating the growth of selected varieties of sugarcane to convert into high-performance jet fuel is underway at the University of Hawai‘i at Hilo College of.
Electric airplanes are only feasible for small planes on short-distance flights and the only electric airplane under development that has substantial range is a hybrid that still requires liquid fuel. Inouye U. The study includes testing modern commercial sugarcane varieties interspecific hybrids of Saccharum spp. H and H Large pot studies are also being conducted to evaluate the nutrient use efficiencies of the selected sugarcane under marginal soil fertility in comparison with an early s variety.
Department of Energy-funded Bioenergy Research Centers. Matlock, a strategic advisor for aviation fuels, said sugarcane was selected as the crop of focus because it is a tremendously prolific biomass plant material producer. But when growing sugarcane solely for sugar, the rest of the crop, specifically major plant biomass components known as lignin, cellulose and hemicellulose, normally go to waste.
The conventional practice of burning sugarcane prior to harvest is to eliminate extra biomass material that previously had limited value, and residual biomass left over after sucrose extraction is typically burned to make power. Converting this biomass into high-valued products such as high performance jet fuel generates more revenue from the same plant material and eliminates incentives to burn crops—reducing air pollution as a bonus.
The end product he mentioned would be the conversion of sugarcane into biofuel for aviation use. This fermentation process is much more ideal than traditional chemical synthesis, which often involves high heat and high pressure to force a reaction.
