Use this biodiesel titration form for calculating the amount of catalyst you will need for making biodiesel from used vegetable oil.
Where did the Oil Come From?
Catalyst used (KOH or NaOH) _______
Base Amount (5g for NaOH, 7g for KOH) ________ [call this a]
Purity of catalyst ___% /100 = ______ [call this b] ( eg . 90% pure KOH would be 90/100=0.9)
Divide the Base Amount [a] by the Purity [b] ______ / ______ = _______ [call this c]. This is now our Adjusted Base Amount.
Titrate three samples of oil and fill in the details below. If any of the results is more than 5% different from the others then throw the sample away and do another one.
Titration 1 ____________ [call this d]
Titration 2 ____________ [call this e]
Titration 3 ____________ [call this f]
Average [d]+[e]+[f] = _________ [call this g]
Total catalyst needed per liter of oil is ______ [c] + ______ [g] = ________ [call this h]
Total Litres of oil to be processed = __________ [call this i ]
Total catalyst needed is [h] x [ i ] = _________ kg
