Environmental Protection Agency under its Clean Air Act. Moreover, it is the only alternative fuel successfully evaluated by the U.S. Biodiesel also contributes to the recycling of waste products, as it is produced from used oils and fats. Moreover, it is less toxic and safe for handling due to a higher flash point. It has lower carbon dioxide emissions as compared to other fuels hence, it reduces the global warming impact and improves human and animal health. ON the third wash I had clear water! Maybe I did get better conversion or maybe it was the gentle washing the first couple of times.Biodiesel is good for the economy, being one of the top renewable fuels and an alternative for petrol and diesel. Didn't seem to make any difference as far as the % of glycerol but I didn't wash so hard on the first couple of washes. I have gotten some emulsions upon vigorous washing so last time I cooked for about an hour vs 45 minutes. Just don't really know how much conversion I have. I put a "t" on top to split the stream going into the unit into the cold and hot connections to get more even distribution and hopefully higher conversion at a quicker rate.

Are GC's easily accessible? I have seen one but don't really know how to use it or who to approach about using one. The user named "neutral" mention using a GC for determining % of conversion. Girl_Mark, You posted on this site about time vs. Good luck, and Guzzler's setup looks really nice (stainless is ideal for all these processes)
I mention this because people often assume that just because they saw glycerol appear, that their process shortcuts must have 'worked'. If you see the glycerol layer appear, it's not a sign that the rest of what's in the container is necessarily biodiesel (it might be some bio and some monoglycerides and diglycerides and oil). But dont' try and speed it up from this time, it's already on the short side.Īnyway, it doesn't cost very much to run a mixer (the initial heating costs a bit more but is still dirt cheap for a 50 gallon batch), and you can put your mixer on a timer after you've added methoxide, so the extra time you put into mixing isn't really 'labor'- you can usually walk away at that point, so there's no need to skimp on it.īasically, mixing time is one of the factors that affects 'conversion' (ie how much of the oily stuff you made is biodiesel rather than monoglycerides and diglycerides), there's no easy way to tell (for a homebrewer) what the exact conversion you achieved was. It's a very rough rule of thumb because the mixing is also affected by the size of pump you're using to mix (or any other mixer) and by the shape of the container. The process time that we usually use for a 50 gallon batch (1-2 hours of mixing) is a rule of thumb that is based on heating to 130F already. That is unless you have a pressurized reactor. However, you shouldn't try to do it above about 140F because methanol boils at 65C or 149F. If I increased the temp to about 145, I could halve the time. I make it at 125-130F and mix for about 40-50 minutes. Supposedly a 10 degree increase in temp will cut process time in half.
