To zahrnuje jeho filtraci, aby se odstranily ne\u010distoty jako zbytky j\u00eddla, voda a dal\u0161\u00ed sedimenty.

Kvalita filtrace je kl\u00ed\u010dov\u00e1 pro fin\u00e1ln\u00ed kvalitu biodieselu.

K odd\u011blen\u00ed vody lze pou\u017e\u00edt odst\u0159edivku nebo nechat olej usadit.<\/p>\n

Transesterifikace<\/p>\n

Toto je hlavn\u00ed krok v procesu v\u00fdroby biodieselu. Zahrnuje reakci pou\u017eit\u00e9ho oleje s methanolem (nebo ethanolem) v p\u0159\u00edtomnosti katalyz\u00e1toru, obvykle hydroxidu sodn\u00e9ho (NaOH) nebo hydroxidu draseln\u00e9ho (KOH).

Odd\u011blen\u00ed glycerolu<\/p>\n

Po dokon\u010den\u00ed transesterifikace je nutn\u00e9 odd\u011blit glycerol od biodieselu. Glycerol, vedlej\u0161\u00ed produkt procesu, se usazuje na dn\u011b n\u00e1doby.

Po umyt\u00ed a su\u0161en\u00ed je biodiesel znovu filtrov\u00e1n, aby se odstranily ve\u0161ker\u00e9 zbyl\u00e9 ne\u010distoty.
