  2. Biodiesel production - Wikipedia

    en.wikipedia.org/wiki/Biodiesel_production

    Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.

  3. Biodiesel - Wikipedia

    en.wikipedia.org/wiki/Biodiesel

    The environmental impact of biodiesel is complex and varies based on factors like feedstock type, land use changes, and production methods. While it can potentially reduce greenhouse gas emissions compared to fossil fuels, concerns about biodiesel include land use changes, deforestation, and the food vs. fuel debate.

  4. Vegetable oils as alternative energy - Wikipedia

    en.wikipedia.org/wiki/Vegetable_oils_as...

    Biodiesel - Biodiesel can be produced from vegetable oil through the process of transesterification. Biodiesel burns like normal diesel and works fine in any diesel engine. The name just indicates that the fuel came from vegetable oil. Straight vegetable oil - Straight vegetable oil works in diesel engines if it is heated first. [5]

    H-Bio, the ConocoPhilips process [7] UOP/Eni Ecofining process. [8] Neste is the largest manufacturer, producing ca. 3.3 million tonnes annually (2023). [9] Neste completed their first NExBTL plant in the summer 2007 and the second one in 2009. Petrobras planned to use 256 megalitres (1,610,000 bbl) of vegetable oils in the production of H-Bio ...

  6. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    The production of biofuels can be very energy intensive, which, if generated from non-renewable sources, can heavily mitigate the benefits gained through biofuel use. A solution proposed to solve this issue is to supply biofuel production facilities with excess nuclear energy, which can supplement the power provided by fossil fuels. [111]

  7. Second-generation biofuels - Wikipedia

    en.wikipedia.org/wiki/Second-generation_biofuels

    The diversion of edible food biomass to the production of biofuels could theoretically result in competition with food and land uses for food crops. First-generation bioethanol is produced by fermenting plant-derived sugars to ethanol, using a similar process to that used in beer and wine-making (see Ethanol fermentation).

  8. Fatty acid methyl ester - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_methyl_ester

    One reason for using FAME (fatty acid methyl esters) in biodiesel production, rather than free fatty acids, is to mitigate the potential corrosion they can cause to metals of engines, production facilities, and related infrastructure. While free fatty acids are only mildly acidic, over time they can lead to cumulative corrosion.

  9. Decarboxylated and decarbonylated biofuels - Wikipedia

    en.wikipedia.org/wiki/Decarboxylated_and_de...

    First generation biofuels such as biodiesel [4] are produced directly from crops, such as cereals, maize, sugar beet and cane, and rapeseed. Second generation fuels are produced from byproducts from production of food and other goods, as well as from household waste, used frying oil from restaurants, and slaughterhouse waste. [5]
