Proces transesterifikace krok za krokem<\/h3>\n
    \n
  1. P\u0159\u00edprava roztoku katalyz\u00e1toru:<\/strong> Katalyz\u00e1tor (nap\u0159. hydroxid sodn\u00fd) se rozpust\u00ed v methanolu. Je nutn\u00e9 dodr\u017eovat p\u0159esn\u00e9 pom\u011bry, aby se dos\u00e1hlo optim\u00e1ln\u00ed reakce.<\/li>\n
  2. Sm\u00edch\u00e1n\u00ed oleje a roztoku katalyz\u00e1toru:<\/strong> Roztok katalyz\u00e1toru se pomalu p\u0159id\u00e1v\u00e1 do p\u0159edeh\u0159\u00e1t\u00e9ho pou\u017eit\u00e9ho kuchy\u0148sk\u00e9ho oleje za st\u00e1l\u00e9ho m\u00edch\u00e1n\u00ed. M\u00edch\u00e1n\u00ed je kl\u00ed\u010dov\u00e9 pro efektivn\u00ed reakci.<\/li>\n
  3. Reakce:<\/strong> Sm\u011bs se nech\u00e1 reagovat po dobu n\u011bkolika hodin p\u0159i ur\u010dit\u00e9 teplot\u011b. Teplota a doba reakce se li\u0161\u00ed v z\u00e1vislosti na pou\u017eit\u00e9m katalyz\u00e1toru a oleji.<\/li>\n
  4. Odd\u011blen\u00ed glycerin a biodiesely:<\/strong> Po dokon\u010den\u00ed reakce se sm\u011bs nech\u00e1 odst\u00e1t. Glycerin, kter\u00fd je t\u011b\u017e\u0161\u00ed, se usad\u00ed na dn\u011b n\u00e1doby, zat\u00edmco biodiesel z\u016fstane naho\u0159e. Odd\u011blen\u00ed se provede opatrn\u00fdm odlit\u00edm biodiesely.<\/li>\n
  5. Myt\u00ed biodiesely:<\/strong> Biodiesel se promyje vodou, aby se odstranily zbytky glycerin a katalyz\u00e1toru. Po umyt\u00ed se biodiesel nech\u00e1 odst\u00e1t, aby se odd\u011blila voda.<\/li>\n
  6. Su\u0161en\u00ed biodiesely:<\/strong> Nakonec se biodiesel vysu\u0161\u00ed, aby se odstranila zb\u00fdvaj\u00edc\u00ed vlhkost.<\/li>\n<\/ol>\n

    \u010ci\u0161t\u011bn\u00ed a filtrace biodiesely<\/h3>\n

    Po transesterifikaci a separaci je nezbytn\u00e9 biodiesel d\u016fkladn\u011b vy\u010distit a filtrovat, aby se odstranily zb\u00fdvaj\u00edc\u00ed ne\u010distoty, glycerin a voda. Kvalita kone\u010dn\u00e9ho produktu z\u00e1vis\u00ed na efektivit\u011b t\u00e9to f\u00e1ze. Pou\u017eit\u00ed vhodn\u00fdch filtr\u016f je kl\u00ed\u010dov\u00e9 pro dosa\u017een\u00ed vysok\u00e9 kvality biodiesely.<\/p>\n

Methanol je toxick\u00fd a pr\u00e1ce s hydroxidem sodn\u00fdm vy\u017eaduje opatrnost. Je nutn\u00e9 pou\u017e\u00edvat ochrann\u00e9 pom\u016fcky, jako jsou rukavice, br\u00fdle a respir\u00e1tor. Pr\u00e1ce by se m\u011bla prov\u00e1d\u011bt v dob\u0159e v\u011btran\u00e9m prostoru.<\/p>\n
