D\u016fle\u017eit\u00e9 je, aby olej nebyl zka\u017een\u00fd nebo \u017elukl\u00e9. 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.

Pro v\u00fdrobu biodiesely budete pot\u0159ebovat n\u011bkolik z\u00e1kladn\u00edch pom\u016fcek. Krom\u011b n\u00e1dob na m\u00edch\u00e1n\u00ed budete pot\u0159ebovat kvalitn\u00ed m\u00edchadlo, nejl\u00e9pe s regulac\u00ed ot\u00e1\u010dek.

Postup v\u00fdroby biodiesely<\/p>\n

    \n
  1. P\u0159\u00edprava methanolu:<\/strong> Methanol se opatrn\u011b sm\u00edch\u00e1 s hydroxidem sodn\u00fdm v samostatn\u00e9 n\u00e1dob\u011b. Reakce je exotermick\u00e1, proto je nutn\u00e9 postupn\u011b p\u0159id\u00e1vat NaOH a n\u00e1dobu chladit.<\/li>\n
  2. Sm\u00edch\u00e1n\u00ed oleje a methanolu:<\/strong> P\u0159ipraven\u00fd roztok se pomalu p\u0159id\u00e1 k rozeh\u0159\u00e1t\u00e9mu rostlinn\u00e9mu oleji. Sm\u011bs se intenzivn\u011b m\u00edch\u00e1 po dobu 60 – 90 minut p\u0159i teplot\u011b okolo 50\u00b0C.<\/li>\n
  3. Odd\u011blen\u00ed glycerinu:<\/strong> Po dokon\u010den\u00ed reakce se sm\u011bs nech\u00e1 n\u011bkolik hodin st\u00e1t, aby se glycerol (vedlej\u0161\u00ed produkt) odd\u011blil od biodiesely. Glycerol je hust\u0161\u00ed a usad\u00ed se na dn\u011b.<\/li>\n
  4. Filtrace:<\/strong> Biodiesela se opatrn\u011b odlije a zfiltruje p\u0159es filtra\u010dn\u00ed materi\u00e1l, aby se odstranily zbytky glycerinu a ne\u010distot.<\/li>\n
  5. Uskladn\u011bn\u00ed:<\/strong> Hotov\u00e1 biodiesela se uskladn\u00ed v \u010dist\u00e9, vzduchot\u011bsn\u00e9 n\u00e1dob\u011b.<\/li>\n<\/ol>\n

Methanol je vysoce toxick\u00fd a jeho v\u00fdpary jsou nebezpe\u010dn\u00e9 pro zdrav\u00ed. V\u017edy pracujte v dob\u0159e v\u011btran\u00e9m prostoru a pou\u017e\u00edvejte ochrann\u00e9 rukavice, br\u00fdle a respir\u00e1tor. Dodr\u017eujte p\u0159esn\u00e9 pom\u011bry surovin a postupujte dle n\u00e1vodu. P\u0159i pr\u00e1ci s hydroxidem sodn\u00fdm je nutn\u00e1 maxim\u00e1ln\u00ed opatrnost, proto\u017ee je \u017e\u00edrav\u00fd.<\/p>\n
