This research is a study of biodiesel production using a catalyst from the shells. The shells will be burned at a temperature of 900 0 C for 4 hours because the shell is burnt in the temperature range of 700-900 will have a very 0C pore ก่วา shell is burnt in the temperature range from 600 OC and present a catalyst analysis X-ray diffraction (XRD) techniques, scanning electron microscope (SEM) techniques, technical energy dispersive spectrometer (EDS), Fourier transform infrared spectrometer technique (FT-IR) technical thermo-gravimetric analysis (TGA), differential scanning calorimetry (DSC) techniques and tricks, Brunauer – Emmett – Teller (BET) on the check, and then is found to accumulate in calcium carbonate shells will change to cache all chrome oxide.Analysis found that the catalyst can be introduced from the shells produce bio-93.3% percent at di through trans esters Arriva app Philadelphia production at a temperature of 65 ± 5 OC using catalyst 3% by mass and the ratio of methanol per oil is 9:1.The gist: bio di Celle, shells, calcium oxide.
