Nejd\u016fle\u017eit\u011bj\u0161\u00ed f\u00e1z\u00ed v\u00fdroby biodieselu je proces transesterifikace. Jedn\u00e1 se o chemickou reakci, p\u0159i n\u00ed\u017e se triglyceridy v rostlinn\u00e9m oleji reaguj\u00ed s methanolem (nebo ethanolem) za p\u0159\u00edtomnosti katalyz\u00e1toru (obvykle hydroxidu sodn\u00e9ho nebo draseln\u00e9ho). V\u00fdsledkem je sm\u011bs methylester\u016f mastn\u00fdch kyselin (biodiesel) a glycerinu (vedlej\u0161\u00ed produkt).<\/p>\n

  1. P\u0159\u00edprava oleje:<\/strong> Olej je t\u0159eba zbavit ne\u010distot a vody. Filtrace p\u0159es pap\u00edrov\u00fd filtr je doporu\u010dena.<\/li>\n
  2. P\u0159\u00edprava roztoku hydroxidu:<\/strong> Hydroxid sodn\u00fd (nebo draseln\u00fd) se rozpust\u00ed v methanolu. Je nutn\u00e9 dodr\u017eovat p\u0159esn\u00e9 pom\u011bry, aby se dos\u00e1hlo optim\u00e1ln\u00edho v\u00fdsledku. Reakce je exotermn\u00ed, proto je nutn\u00e9 chlazen\u00ed.<\/li>\n

Intenzita m\u00edch\u00e1n\u00ed ovliv\u0148uje rychlost a efektivitu reakce.

  5. Myt\u00ed a \u010di\u0161t\u011bn\u00ed:<\/strong> Biodiesel je nutn\u00e9 propl\u00e1chnout vodou, aby se odstranily zbytky glycerinu a katalyz\u00e1toru. Potom je nutn\u00e9 ho vysu\u0161it.<\/li>\n
  6. Filtrace:<\/strong> Z\u00e1v\u011bre\u010dn\u00e1 filtrace odstran\u00ed ve\u0161ker\u00e9 zb\u00fdvaj\u00edc\u00ed ne\u010distoty.<\/li>\n<\/ol>\n
