Catalysts for Biodiesel

A key ingredient in the homebrew biodiesel recipe is catalyst. Sodium Hydroxide and Potassium Hydroxide are the most commonly used. The glycerin and soap that settles out from a reaction using Sodium Hydroxide will be solid, while the soap and glycerin that settles out from a reaction using Potassium Hydroxide will be liquid.  



Methanol for Biodiesel

Methanol or wood grain alcohol is the simplest form of alcohol. It is both poisonous and flammable. It is used in racing, making it available at both chemical supply houses and fuel distributors. It burns without a visible flame in bright sunlight and it is the most expensive ingredient for most homebrewers.




Oil for Making Biodiesel

There is a huge variation in fats and oils used to make biodiesel. This article goes into the properties of the different oils to help you know which are best for making biodiesel. For instance, how much saturated fat an oil contains determines it's gel point.





Titrating WVO before Making Biodiesel

Titrating WVO is essential to understanding the quality of your oil. It is a simple test and is used to build a biodiesel recipe. This article contains instructions and videos on how to tirate.





How to Collect Waste Vegetable Oil

Collecting WVO for Making Biodiesel

Cheap and free oil is what makes homebrew economical. Homebrewers have a big advantage over commercial producers because they can pick up oil on their way to and from work. Commercial producers either have to buy their oil and pay to have it delivered or have to hire a driver to collect oil directly from restaurants.




Drying WVO for Biodiesel

The most common cause of problems such as emulsions and low quality conversions when making biodiesel fuel is water in the feedstock oil. You cannot tell by looking at the oil if it is dry or wet. Usually Cloudy oil is an indication of wet oil and clear oil is usually an indication of dry oil, but that is not always the case.
