Proces v\u00fdroby<\/p>\n

Nejprve je t\u0159eba p\u0159ipravit roztok hydroxidu sodn\u00e9ho v methanolu. To se d\u011bl\u00e1 pomal\u00fdm p\u0159id\u00e1v\u00e1n\u00edm hydroxidu sodn\u00e9ho do methanolu za st\u00e1l\u00e9ho m\u00edch\u00e1n\u00ed. Reakce je exotermn\u00ed, tak\u017ee se sm\u011bs bude zah\u0159\u00edvat. Po \u00fapln\u00e9m rozpu\u0161t\u011bn\u00ed hydroxidu sodn\u00e9ho se p\u0159id\u00e1 pou\u017eit\u00fd rostlinn\u00fd olej a sm\u011bs se d\u016fkladn\u011b prom\u00edch\u00e1. Reakce prob\u00edh\u00e1 za zv\u00fd\u0161en\u00e9 teploty (kolem 50-60 \u00b0C) a trv\u00e1 n\u011bkolik hodin.

Po ukon\u010den\u00ed reakce se nech\u00e1 sm\u011bs ust\u00e1t, aby se odd\u011blily dv\u011b vrstvy: biodiesel naho\u0159e a glycerin dole.<\/p>\n

Po odd\u011blen\u00ed vrstev se biodiesel odd\u011bl\u00ed od glycerinu. Glycerin je vedlej\u0161\u00ed produkt, kter\u00fd lze pou\u017e\u00edt v kosmetick\u00e9m pr\u016fmyslu nebo jako hnojivo. Biodiesel je pak nutn\u00e9 propl\u00e1chnout vodou, aby se odstranily zbytky glycerinu a methanolu. K tomu se pou\u017e\u00edv\u00e1 separ\u00e1tor, kter\u00fd umo\u017e\u0148uje efektivn\u00ed odd\u011blen\u00ed vody a biodiesely.

V\u00fdroba biodiesely doma vy\u017eaduje maxim\u00e1ln\u00ed opatrnost. Methanol a hydroxid sodn\u00fd jsou vysoce toxick\u00e9 a \u017e\u00edrav\u00e9 l\u00e1tky. V\u017edy dodr\u017eujte bezpe\u010dnostn\u00ed pokyny a pracujte v dob\u0159e v\u011btran\u00e9m prostoru. Pou\u017e\u00edvejte ochrann\u00e9 rukavice, br\u00fdle a z\u00e1st\u011bru.

Testov\u00e1n\u00ed a skladov\u00e1n\u00ed<\/p>\n

Po dokon\u010den\u00ed v\u00fdroby a \u010di\u0161t\u011bn\u00ed je vhodn\u00e9 otestovat kvalitu biodiesely. Existuj\u00ed testy na stanoven\u00ed obsahu voln\u00fdch mastn\u00fdch kyselin a vody.
