    \n
  1. Filtrace:<\/strong> Olej je nutn\u00e9 d\u016fkladn\u011b filtrovat, aby se odstranily pevn\u00e9 ne\u010distoty, zbytky potravin a jin\u00e9 ne\u017e\u00e1douc\u00ed l\u00e1tky.

    Transesterifikace<\/p>\n

    Nejd\u016fle\u017eit\u011bj\u0161\u00edm krokem p\u0159i v\u00fdrob\u011b biodieselu z kuchy\u0148sk\u00e9ho oleje je transesterifikace. Tento proces zahrnuje reakci triglycerid\u016f v oleji s alkoholem (obvykle methanolem nebo ethanolem) za p\u0159\u00edtomnosti katalyz\u00e1toru (obvykle hydroxidu sodn\u00e9ho nebo draseln\u00e9ho). V d\u016fsledku t\u00e9to reakce vznikaj\u00ed mastn\u00e9 kyseliny methylestery (FAME), kter\u00e9 tvo\u0159\u00ed biodizel, a glycerin, kter\u00fd je vedlej\u0161\u00edm produktem. Proces transesterifikace vy\u017eaduje specifick\u00e9 podm\u00ednky teploty a tlaku a pe\u010dliv\u00e9 sledov\u00e1n\u00ed reakce.<\/p>\n

    \u010ci\u0161t\u011bn\u00ed a separace<\/p>\n

    Po transesterifikaci je nutn\u00e9 produkt o\u010distit a odd\u011blit biodizel od glycerinu. To se prov\u00e1d\u00ed pomoc\u00ed separace, kter\u00e1 vyu\u017e\u00edv\u00e1 rozd\u00edlnou hustotu biodieselu a glycerinu. Glycerin se odd\u011bl\u00ed a m\u016f\u017ee b\u00fdt d\u00e1le zpracov\u00e1n. Biodizel se pak promyje vodou, aby se odstranily zbytky katalyz\u00e1toru a glycerinu.<\/p>\n

    Kvalita a vlastnosti biodieselu<\/p>\n

    Kvalita vyroben\u00e9ho biodieselu z\u00e1vis\u00ed na mnoha faktorech, v\u010detn\u011b kvality pou\u017eit\u00e9ho oleje, spr\u00e1vn\u00e9ho proveden\u00ed transesterifikace a dal\u0161\u00edch proces\u016f \u010di\u0161t\u011bn\u00ed. Vlastnosti biodieselu, jako je cetanov\u00e9 \u010d\u00edslo, viskozita a obsah vody, by m\u011bly spl\u0148ovat normy pro pou\u017eit\u00ed v dieselov\u00fdch motorech.
