Proces transesterifikace<\/p>\n

Transesterifikace je chemick\u00e1 reakce, p\u0159i kter\u00e9 se triglyceridy v oleji reaguj\u00ed s methanolem za p\u0159\u00edtomnosti katalyz\u00e1toru (NaOH nebo KOH). V\u00fdsledkem t\u00e9to reakce je biodiesel (methylestery mastn\u00fdch kyselin) a glycerin. Proces se obvykle d\u011bl\u00ed na n\u011bkolik krok\u016f:<\/p>\n

    \n
  1. P\u0159\u00edprava roztoku katalyz\u00e1toru:<\/strong> Hydroxid sodn\u00fd se rozpust\u00ed v methanolu. Tato reakce je exotermick\u00e1, proto je nutn\u00e9 db\u00e1t na bezpe\u010dnost a chlazen\u00ed.<\/li>\n
  2. Sm\u00edch\u00e1n\u00ed oleje a roztoku katalyz\u00e1toru:<\/strong> Roztok katalyz\u00e1toru se pomalu p\u0159id\u00e1 k oh\u0159\u00e1t\u00e9mu oleji za st\u00e1l\u00e9ho m\u00edch\u00e1n\u00ed.

  3. Reak\u010dn\u00ed f\u00e1ze:<\/strong> Sm\u011bs se nech\u00e1 reagovat po dobu n\u011bkolika hodin p\u0159i ur\u010dit\u00e9 teplot\u011b (obvykle kolem 50-60 \u00b0C) a za st\u00e1l\u00e9ho m\u00edch\u00e1n\u00ed. D\u00e9lka reakce z\u00e1vis\u00ed na pou\u017eit\u00e9m oleji a katalyz\u00e1toru.<\/li>\n
  4. Odd\u011blen\u00ed glycerinu:<\/strong> Po ukon\u010den\u00ed reakce se sm\u011bs nech\u00e1 odst\u00e1t, aby se odd\u011blil glycerin (t\u011b\u017e\u0161\u00ed frakce) od biodieselu. Glycerin se d\u00e1 n\u00e1sledn\u011b d\u00e1le zpracovat.<\/li>\n
  5. Myt\u00ed a \u010di\u0161t\u011bn\u00ed biodieselu:<\/strong> Biodiesel se promyje vodou, aby se odstranily zbytky glycerinu, metanolu a katalyz\u00e1toru. Kvalita myt\u00ed m\u00e1 velk\u00fd vliv na kvalitu fin\u00e1ln\u00edho produktu.<\/li>\n
  6. Su\u0161en\u00ed biodieselu:<\/strong> Nakonec se biodiesel usu\u0161\u00ed, aby se odstranila zb\u00fdvaj\u00edc\u00ed voda.<\/li>\n<\/ol>\n

    Po v\u00fdrob\u011b je d\u016fle\u017eit\u00e9 ov\u011b\u0159it kvalitu biodieselu. To zahrnuje m\u011b\u0159en\u00ed obsahu vody, voln\u00fdch mastn\u00fdch kyselin a dal\u0161\u00edch parametr\u016f, kter\u00e9 ur\u010duj\u00ed jeho vlastnosti a kompatibilitu s dieselov\u00fdmi motory.
