biodiesel /methanol separation Articles

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • Making biodiesel blends fuel is simple

    Biodiesel is made in the process of transesterification of vegetable oil by methanol, although sometimes ethanol or isopropyl alcohol are used instead. The ration is approximately 200 kg of methanol per 1 ton of oil (plus potassium or sodium hydroxide). Process temperature is approximately 60°С, no pressure increase is required. After the transesterification reaction, the content of ...

  • Hielscher – Ultrasonic Transesterification of Oil to Biodiesel Improves Reaction Speed and Yield

     Ultrasonication can improve the conversion processing of vegetable oils or animal fats to biodiesel by improved mixing and enhanced chemical activity. The manufacturing of biodiesel from oils (e.g. soy, canola, sunflower seed) or animal fats, involves the base-catalyzed transesterification of fatty acids with methanol to give the corresponding methyl esters. The conventional esterification ...

  • Modification of thermal and oxidative properties of biodiesel produced from vegetable oils

    Trans esterification of three vegetable oils, sunflower oil, linseed oil and mixed oils as; sunflower-soyabean and olein were carried out using methanol, and potasium hydroxide as catalyst. The methyl esters of the corresponding oils were separated from the crude glycerol and characterized by physical-chemical methods to evaluate their thermal ...
