The document discusses optimizing biodiesel production from sunflower oil using response surface methodology. Specifically, it evaluated the effects of reaction temperature, catalyst concentration, and molar ratio of methanol to oil on biodiesel yield. Sunflower oil, methanol, and potassium hydroxide were used. Experiments involved adding potassium methoxide to sunflower oil and maintaining it for 2 hours to complete transesterification, then separating and washing the biodiesel. Response surface analysis found temperature has an important influence on reaction speed and conversion, with higher temperatures increasing conversion but lower temperatures reducing it below methanol's critical state. The conclusion is that biodiesel can suitably replace petro-diesel without engine modifications.

2. Biodiesel, is a plant
deriver product , it is
not toxic, biodegradable
and, available, has a
high heat value, high
oxigen content and does
not cointain suulfurs
and aromatic
compounds.

3. OBJETIVES
Our work was to evaluate the efects of the reactions parameters of the
temperature. Catalyst concentration and molar ratio of methanor to oil
on the biodiesel yield to optimize the reaction condition using rsm

4. MATERIALS AND EQUIPMENTS
Sunflowers oil, methanol a purity of 99,5%, and potassium
hidroside(koh).
The reactor empcoyed was a lr 2000p modularly expandable
laboratory reactor.
EQUIPMENTS
MATERIALS

5. ESPERIMENTS AND METHODS
2 litres off sunflower oil -> 290 rpm -> the potassium methoxide was
added -> was maintained for 2 hours -> transesterification was completed
-> to separates biodiesel from glycerol.
Biodiesel wash washer out 10 times -> until the color water shifts to white
-> finally, was dried by silica jell.

6. RESPONSE SURFACE ANALYSIS
The temperature has an important influence on speed of reaction an led
to higher conversion of ester.
Hight temperature -> increased quickly the boiling point of alcohol.
Low temperature -> low conversion to methyl ester to the surcritical state
of methanol.

7. CONCLUSION
We can conclude thet biodiesel will be suitable
alternative to replacement petro-diesel without any
modification in engine.
