How to make biodiesel

Biodiesel is an alternative fuel for diesel engines made from vegetable oil or animal fat. Since it is derived from renewable organic materials and has been shown to reduce certain harmful emissions when burned compared to conventional diesel, bio-diesel has received wide attention as a “green” source of energy. Here are steps to synthesize this renewable fuel yourself.

Generally speaking, bio-diesel is an alternative or additive to standard diesel fuel that is made from biological ingredients instead of petroleum. And oils are just fats that are liquid at room temperature. The common thread shared by all bio-diesel sources is that they all contain fat in some form. These fats namely triacylglycerols are made up of hydrogen, carbon and oxygen atoms bound together and arranged into a specific pattern. These triacylglycerols are pretty pervasive. In addition to household vegetable oils, they’re also in general things like lard and butter. You could have seen a triglyceride count listed if you’ve been to a doctor and had some blood work done. There is only one way to visualize these fats as is to consider the capital letter “E”. The vertical skeleton that forms this E is a molecule called glycerol. Glycerin is a common ingredient for the manufacture of soaps, medicines and cosmetics. The horizontal element attached to this glycerol skeleton and forming E is three long chains of carbon, hydrogen and oxygen. These are called fatty acids.

Back to the topic, how to make bio-diesel? There are some process below to show you making it by yourself:

Obtain high quality oil

For bio diesel making, the easiest oils are neutral vegetable oils such as canola, sunflower oil and corn. These oils are readily to buy at grocery stores or convenient shop, even supermarket and it has a low melting point, which means they will not solidify through too cold environment as depository. There are some tips below,

1. Avoid using peanut oil, coconut oil, palm oil, tallow, and lard. These sources of oil solidify at relatively high temperatures. Bio-diesel usually has a lower melting point than the oil it’s made from, but these oils can still be difficult for beginners.

2. Avoid olive oil. It, peanut oil, palm oil, tallow, and lard all contain more acids than in the recommended neutral oils. These extra acids can interfere with the reactions that take place to create the bio-diesel.

Work in a safe place

You can find suitable laboratories at most colleges and research institutions. Working at home is also possible but requires caution – manufacturing your own bio diesel may be illegal and can put your house at risk of a fire, smoke or carbon monoxide. But the main points are about well-ventilated and have clear access to running water, fire extinguisher, eye-wash stations.

Let’s do it

Heat the oil you prepared to 120 F, then add the calculated amount of methanol/hydroxide mixture. The FuelMeister processor we used conveniently lets you do the methanol/lye mixing inside a tank mounted to the lid. Agitate for an hour by running the transfer-pump hose back into the vessel. At this point the oil will have been converted into biodiesel. Allow the heavier glycerin to settle out for a few hours. Drain the glycerin from the bottom until you get lighter-colored, thinner biodiesel pouring from the valve. Then use water to wash the excess methanol, lye and soapy residue from the biodiesel. The water will settle to the bottom of the vessel in a few hours, where you can drain it out. That is cool, you may produce bio-diesel by yourself.

The ones and twos about Bio-Diesel

Nowadays, the most of article, snippet was related to the oil or its price if you have read news or watched TV for the news lately. Certainly, this is necessary things we care daily because normally we drive the cars or related vehicles or other transport tools, some machines using fuels for our destination of offices, sea port or workshop. But following advanced science and technology to be developed, recently there is one alternative for gas fuel as biodiesel.

What is biodiesel? This new thing still not comes in our daily life to be used by us however i trust its value will attract our eye and finally mass and lot production for that. Actually bio-diesel is a renewable fuel made from biomass. Most bio-diesel from America is produced from animal fats and vegetable oils. Bio-diesel can be used in the same equipment as diesel fuel made from petroleum. The major sources of feedstock (raw material) for making bio-diesel in the United States and their shares of total bio-diesel raw material in 2017 as below,

Soybean oil—52%

Canola oil—13%

Corn oil—13%

Recycled feedstocks, such as used cooking oils and yellow grease—12%

Animal fats—10%

Certainly, related data show that in other countries bio-diesel has been produced by main ingredient Rapeseed oil, sunflower oil, and palm oil and so on. So how bio-diesel works is another attention by people.

Bio-diesel environmentally friendly

Emissions control is main issue to the bio-diesel argument, particularly in legislation matters. At the present, there are a few harmful components of emission to cause concern among scientists, consumers and lawmakers. However this is the major selling point for bio-diesel that it is environmentally friendly. Bio diesel after testing, it has fewer emissions than standard diesel, is biodegradable, and is a renewable source of energy. Bio diesel may reduce harmful emissions. About the present bio-fuel, bio diesel is the only one to have successfully completed emissions testing in terms of the Clean Air Act.

Bio diesel is also safer. It is non-toxic and has a higher flashpoint comparing to conventional diesel. Because it burns at a higher temperature, it is less likely to accidentally combust. This makes movement and storage regulations easier to accommodate. Next, we will look at the cons and the future of bio-diesel.

Bio-diesel can match to any engine using standard diesel

Bio-diesel is most often blended with petroleum diesel in ratios of 2% (referred to as B2), 5% (B5), or 20% (B20). Bio-diesel can also be used as pure bio-diesel (B100). It as new fuel can be used in regular diesel engines without making any modification to the engines. Meanwhile, Bio-diesel blends are also

used as heating oil. Bio-diesel can be stored and transported using petroleum diesel fuel tanks and equipment.

Bio-diesel may lubricate the engine

Actually bio-diesel is estimated that a bio diesel blend of just 1 percent could increase fuel lubricity by as much as 65 percent (U.S. DOE Office of Transportation Technology). It also contributes to an engine’s lubricity, or ease of movement about engines. It acts as a solvent, which helps to loosen deposits and other gunk from the insides of an engine that could potentially cause clogs. Since pure bio-diesel leaves no deposits of its own, this will definitely increased engine life as well.
