NEXBTL
Neste MY Renewable Diesel (formerly NExBTL) is a vegetable oil refining fuel production process commercialized by the Finnish oil and refining company Neste. Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems. Neste guarantees that every gallon sold meets ASTM D975 and EN 15940 specifications in compliance with OEM standards. Despite the former name BTL, the feedstock is vegetable oil and waste animal fats, not whole plants. However, fuel quality is equal to the synthetic Fischer-Tropsch BTL and GTL diesel fuels. Process Neste Renewable Diesel is produced in a patented vegetable oil refining process. Chemically, it entails direct catalytic hydrodeoxygenation (hydrogenolysis) of plant oils, which are triglycerides, into the corresponding alkanes and propane. The glycerol chain of the triglyceride is hydrogenated to the corresponding C3 alkane, propane — there is no glycerol sidestream. This proc ...

Hydrodeoxygenation
Hydrodeoxygenation (HDO) is a hydrogenolysis process for removing oxygen from oxygen-containing compounds. Typical HDO catalysts commonly are sulfided nickel-molybdenum or cobalt-molybdenum on gamma alumina. An idealized reaction is: :R2O + 2 H2 -> H2O + 2 RH The first review on HDO was published in 1983. HDO is of interest in producing biofuels Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic ..., which are derived from oxygen-rich precursors like sugars or lipids. An example of a biomass refining process employing hydrodeoxygenation is the NEXBTL process. HDO of biomass fast pyrolysis vapors under low hydrogen pressures have recently attracted a lot of attention. Bulk molybdenum trioxide (MoO3) was used as catalyst and found to completely deoxygenate cellulose, corn stover, and li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm Oil
Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of oil palms. The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 36% of global oils produced from oil crops in 2014. Palm oils are easier to stabilize and maintain quality of flavor and consistency in ultra-processed foods, so they are frequently favored by food manufacturers. Globally, humans consumed an average of of palm oil per person in 2015. Demand has also increased for other uses, such as cosmetics and biofuels, encouraging the growth of palm oil plantations in tropical countries. The mass production of palm oil in the tropics has attracted the concern of environmental and human rights groups. The palm oil industry is a significant contributor to deforestation in the tropics where palms are grown and has been cited as a factor in social problems due to allegations of human rights violations among growers. In 2018, a repor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jatropha Oil
''Jatropha curcas'' is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics: Mexico, the Caribbean and Central and South America. It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many areas. The specific epithet, ''"curcas"'', was first used by Portuguese doc Garcia de Orta more than 400 years ago. Common names in English include physic nut, Barbados nut, poison nut, bubble bush or purging nut. In parts of Africa and areas in Asia such as India it is often known as "castor oil plant" or "hedge castor oil plant", but it is not the same as the usual castor oil plant, ''Ricinus communis'' (they are in the same family but different subfamilies). ''Jatropha curcas'' is a semi-evergreen shrub or small tree, reaching a height of or more. It is resistant to a high d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae Fuel
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that use algae as the source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil. These fuels have no practical significance but remain an aspirational target in the biofuels research area. History In 1942 Harder and Von Witsch were the first to propose that microalgae be grown as a source of lipids for food or fuel. Following World War II, research began in the US, Germany, Japan, England, and Israel on culturing techniques and engineering systems for growing microalgae on larger scales, particularly species in the genus '' Chlorella''. Meanwhile, H. G. Aach showed that '' Chlorella pyrenoidosa'' could be induced via nitrogen starvation to accumulate as much as 70% of its dry weight as lipids. Since the need for alternative transportation fuel h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogas
Biogas is a gaseous renewable energy source produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, Wastewater treatment, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an Anaerobic digestion, anaerobic digester, biodigester or a bioreactor. The gas composition is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The methane can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for heating purpose, such as in cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. After removal of carbon dioxide and hydrogen sulfide it can be compressed natural gas, compressed in the same way as natural gas and used to power Alternative fuel vehicle, motor vehicles. In the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapeseed Oil
Close-up of canola blooms Canola flower Rapeseed oil is one of the oldest known vegetable oils. There are both edible and industrial forms produced from rapeseed, the seed of several cultivars of the plant family Brassicaceae. Historically, it was restricted as a food oil due to its content of erucic acid. Laboratory studies about this acid have shown damage to the cardiac muscle of laboratory animals in high quantities. It also imparts a bitter taste, and glucosinolates, which made many parts of the plant less nutritious in animal feed. Rapeseed oil from standard cultivars can contain up to 54% erucic acid. Canola oil is a food-grade version derived from rapeseed cultivars specifically bred for low acid content. It is also known as low erucic acid rapeseed (LEAR) oil and is generally recognized as safe by the United States Food and Drug Administration.ecfr.gov version Canola oil is limited by government regulation to a maximum of 2% erucic acid by weight in the US a ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerate ...

Palm Oil Diesel
Vegetable oils are increasingly used as a substitute for fossil fuels. Vegetable oils are the basis of biodiesel, which can be used like conventional diesel. Some vegetable oil blends are used in unmodified vehicles, but straight vegetable oil often needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity and surface tension, sometimes specially made injector nozzles, increased injection pressure and stronger glow-plugs, in addition to fuel pre-heating is used. Another alternative is vegetable oil refining. The availability of biodiesel around the world is increasing, although still tiny compared to conventional fossil fuel sources. There is significant research in algaculture methods to make biofuel from algae. Concerns have been expressed about growing crops for fuel use rather than food and the environmental impacts of large-scale agriculture and land clearing required to expand the production of vegetable oil for fuel use. These effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Political Corruption
Political corruption is the use of powers by government officials or their network contacts for illegitimate private gain. Forms of corruption vary but can include bribery, lobbying, extortion, cronyism, nepotism, parochialism, patronage, influence peddling, Graft (politics), graft, and embezzlement. Corruption may facilitate criminal enterprise, such as drug trafficking, money laundering, and human trafficking, although it is not restricted to these activities. Over time, corruption has been defined differently. For example, while performing work for a government or as a representative, it is unethical to accept a gift. Any free gift could be construed as a scheme to lure the recipient towards some biases. In most cases, the gift is seen as an intention to seek certain favors, such as work promotion, tipping in order to win a contract, job, or exemption from certain tasks in the case of junior worker handing in the gift to a senior employee who can be key in winning the favor. ...
