V\u00fdb\u011br surovin<\/p>\n

Nejd\u016fle\u017eit\u011bj\u0161\u00ed surovinou pro v\u00fdrobu biodieselu je rostlinn\u00fd olej. Nej\u010dast\u011bji se pou\u017e\u00edv\u00e1 \u0159epkov\u00fd olej, slune\u010dnicov\u00fd olej, s\u00f3jov\u00fd olej a dal\u0161\u00ed rostlinn\u00e9 oleje s vysok\u00fdm obsahem triglycerid\u016f. Kvalita oleje ovliv\u0148uje kvalitu v\u00fdsledn\u00e9ho biodieselu. Pou\u017eit\u00ed pou\u017eit\u00e9ho fritovac\u00edho oleje je mo\u017en\u00e9, ale vy\u017eaduje d\u016fkladn\u011bj\u0161\u00ed \u010di\u0161t\u011bn\u00ed. Druhou kl\u00ed\u010dovou surovinou je methanol (methylalkohol), siln\u011b jedovat\u00e1 l\u00e1tka, s n\u00ed\u017e je nutn\u00e9 zach\u00e1zet s maxim\u00e1ln\u00ed opatrnost\u00ed. Je d\u016fle\u017eit\u00e9 pou\u017e\u00edvat \u010dist\u00fd methanol, bez ne\u017e\u00e1douc\u00edch p\u0159\u00edm\u011bs\u00ed. Katalyz\u00e1tor, obvykle hydroxid sodn\u00fd (NaOH) nebo hydroxid draseln\u00fd (KOH), urychluje reakci transesterifikace.<\/p>\n

Proces transesterifikace<\/p>\n

Transesterifikace je chemick\u00e1 reakce, p\u0159i kter\u00e9 se triglyceridy v rostlinn\u00e9m oleji reaguj\u00ed s methanolem za p\u0159\u00edtomnosti katalyz\u00e1toru, \u010d\u00edm\u017e vznik\u00e1 biodiesel (methylestery mastn\u00fdch kyselin) a glycerin. Tento proces prob\u00edh\u00e1 v n\u011bkolika kroc\u00edch:<\/p>\n

    \n
  1. P\u0159\u00edprava roztoku katalyz\u00e1toru:<\/strong> Hydroxid sodn\u00fd se rozpust\u00ed v methanolu. Je nutn\u00e9 db\u00e1t na bezpe\u010dnostn\u00ed opat\u0159en\u00ed, proto\u017ee reakce je exotermick\u00e1 a m\u016f\u017ee v\u00e9st k pop\u00e1len\u00ed.<\/li>\n
  2. Sm\u00edch\u00e1n\u00ed surovin:<\/strong> P\u0159ipraven\u00fd roztok katalyz\u00e1toru se pomalu p\u0159id\u00e1 k rostlinn\u00e9mu oleji. Sm\u011bs se d\u016fkladn\u011b prom\u00edch\u00e1.

  3. Reakce:<\/strong> Sm\u011bs se nech\u00e1 reagovat po dobu n\u011bkolika hodin p\u0159i teplot\u011b kolem 50-60 \u00b0C. B\u011bhem reakce se postupn\u011b odd\u011bluje glycerin od biodieselu.<\/li>\n
  4. Separace:<\/strong> Po ukon\u010den\u00ed reakce se sm\u011bs nech\u00e1 usadit, aby se glycerin odd\u011blil od biodieselu. Glycerin je hust\u0161\u00ed a usad\u00ed se na dn\u011b n\u00e1doby.<\/li>\n
  5. Myt\u00ed:<\/strong> Biodiesel se n\u00e1sledn\u011b umyje vodou, aby se odstranily zbytky glycerinu a katalyz\u00e1toru.<\/li>\n
  6. Su\u0161en\u00ed:<\/strong> Po umyt\u00ed se biodiesel usu\u0161\u00ed, aby se odstranila zb\u00fdvaj\u00edc\u00ed voda.<\/li>\n<\/ol>\n\n\n\n\n\n\n\n\n\n\n
