Proces transesterifikace<\/h3>\n

Transesterifikace je chemick\u00e1 reakce, p\u0159i kter\u00e9 se triglyceridy v oleji nebo tuku reaguj\u00ed s alkoholem (nej\u010dast\u011bji methanolem) za p\u0159\u00edtomnosti katalyz\u00e1toru (obvykle hydroxidu sodn\u00e9ho nebo draseln\u00e9ho). V\u00fdsledkem t\u00e9to reakce je biodiesel (methyl-estery mastn\u00fdch kyselin) a glycerin. Tento proces je z\u00e1kladem v\u00fdroby biodieselu.<\/p>\n

Postup v\u00fdroby biodieselu<\/h3>\n
    \n
  1. P\u0159\u00edprava oleje:<\/strong> Olej se zbav\u00ed ne\u010distot a vody. V p\u0159\u00edpad\u011b pou\u017eit\u00e9ho oleje je nutn\u00e9 ho d\u016fkladn\u011bji vy\u010distit filtrac\u00ed a p\u0159\u00edpadn\u011b usadit.<\/li>\n
  2. P\u0159\u00edprava roztoku hydroxidu:<\/strong> Hydroxid sodn\u00fd (NaOH) se rozpust\u00ed v methanolu. Toto je exotermick\u00e1 reakce, proto je nutn\u00e9 postupovat opatrn\u011b a pou\u017e\u00edvat ochrann\u00e9 pom\u016fcky. Pom\u011br NaOH a methanolu je z\u00e1visl\u00fd na zvolen\u00e9 metod\u011b v\u00fdroby.<\/li>\n
  3. Sm\u00edch\u00e1n\u00ed:<\/strong> Roztok hydroxidu se pomalu p\u0159id\u00e1v\u00e1 k zah\u0159\u00e1t\u00e9mu oleji za st\u00e1l\u00e9ho m\u00edch\u00e1n\u00ed. Tato f\u00e1ze je kritick\u00e1 pro \u00fasp\u011bch cel\u00e9ho procesu.<\/li>\n
  4. Reakce:<\/strong> Reakce prob\u00edh\u00e1 n\u011bkolik hodin p\u0159i m\u00edrn\u011b zv\u00fd\u0161en\u00e9 teplot\u011b (kolem 50-60 \u00b0C). Doba reakce z\u00e1vis\u00ed na kvalit\u011b surovin a pou\u017eit\u00e9m katalyz\u00e1toru.<\/li>\n
  5. Odd\u011blen\u00ed glycerin\u016f:<\/strong> Po ukon\u010den\u00ed reakce se sm\u011bs nech\u00e1 usadit. Glycerin se usad\u00ed na dn\u011b n\u00e1doby a biodiesel se nach\u00e1z\u00ed naho\u0159e. Odd\u011blen\u00ed lze usnadnit pomoc\u00ed separ\u00e1toru.<\/li>\n
  6. O\u010di\u0161t\u011bn\u00ed:<\/strong> Biodiesel se promyje vodou, aby se odstranily zbytky glycerin\u016f a katalyz\u00e1toru. Pot\u00e9 se nech\u00e1 usadit a zbavit se zb\u00fdvaj\u00edc\u00ed vody.<\/li>\n
  7. Filtrace:<\/strong> Pro dosa\u017een\u00ed dokonal\u00e9 \u010distoty se biodiesel filtruje p\u0159es filtr pap\u00edr.<\/li>\n<\/ol>\n
