We used 50 liters of oil that was cleaned using glycerin byproduct. It titrated at 2 KOH.
The other 50 liters was straight out of the drum from the deep fryer. It had settled about a month and looked clear. It titrated at 4 KOH.
Mixed it titrated at 3 KOH.
The first mix was hard for about 6 mins at 150F. Total mixing about 12 mins. over 45 mins time.
I used 9 for a base using 85% KOH. That is 9 grams base per liter KOH out of the bag plus 3 grams for titration.
5.5 gallons methanol for 100 liters of oil because I wanted to make high conversion biodiesel single stage for sure !
We passed 3/27 at 68F. It was clear. No cloudiness at all ! :)
Greengril and I did the 3/27 test. No dropout.
