Hello Seth. Biodiesel is usually processed at as low temperature as possible, 60oC is almost ideal. Any temperature above that is threateing. The hotter the faster the crack. ----- Original Message ----- From: "Seth Macdonald" <[EMAIL PROTECTED]> To: <sustainablelorgbiofuel@sustainablelists.org> Sent: Sunday, February 27, 2011 10:08 PM Subject: Re: [Biofuel] Query on breaking emulsions
At what temp does Bio-Diesel start to crack? Perhaps it is not a great idea to use it in a hydronic system. If the Bio-diesel is only circulated for 24 hrs before being replaced by the next batch, am I still in danger of losing quality?

High temperatures may cause the biodiesel to crack and form solids, so filtering is necessary to keep the circulation running. And the biodiesel will in each case loose quality in connection to heating. The higher degree of unsaturation, the greater the quality loss.But the process can be buffered by the use of anti-oxidants, preferably the BHT based. ----- Original Message ----- From: "Seth Macdonald" <[EMAIL PROTECTED]> To: <sustainablelorgbiofuel@sustainablelists.org> Sent: Tuesday, February 22, 2011 8:16 PM Subject: Re: [Biofuel] Query on breaking emulsions > Thanks for the tips Keith. > > the "Journey to Forever" website has revolutionized my family's life! > Everything > I have learned thus far about Bio-Diesel has been learned from going to > your > site and hands on experience.
