my name is david, chemical eng. student at state polytechnic of bandung, indonesia. i'm doing the final assignment to produce biodiesel.
thanks for the information keith, i can understand the answer. the only reason i ask, is just the cost of pure methanol is expensive. it's hard too make the product economically. and keith, i'm not trying the palm oil, but the coconut oil. what will be if i use the palm oil ? may i know what oil have been used by you and the other ? i got another question : 1. i made my biodiesel, but in the end, i have one separated glycerine is still liquid even in the room temperature ( isn't the temperature to keep glycerine in liquid is above of 38 C ? ) and i got one still solid even in 40 C and semi gel in 50 C. Is there anyone know how could it be ? 2. i would like to ask everybody, what's the rate per liter of any diesel fuel in every country, is there any list about it ? please tell me what's the rate per liter any diesel fuel in your country. 3. what could be the effect to the diesel engine if we made the product, say , the density is below the standard ? 4. i'm trying to made biodiesel based on the mike pelly's method to produce a half liter, but i get none but failure. looks like it was soap formation that happened. i'm trying to reduce the amount of NaOH used to half of 3.5 grams and too half of the amount from the titration, but still the soap is formed. is there any calibration rate to produce half or double ? for example say we made it 10 litres and the amount from titration is 2,2 ml. is it mean ( 2.2 + 3.5 ) per liter = 5.7 gr NaOH per liter or 57 grams NaOH ? or there is another way of calculating ? i think that will be enough for now. i really apprecate to you guys, you're more than a teacher for me. thanks. david __________________________________________________ Do You Yahoo!?
