Z\u00e1kladn\u00ed suroviny pro v\u00fdrobu biodieselu jsou rostlinn\u00e9 oleje (nap\u0159. \u0159epkov\u00fd, slune\u010dnicov\u00fd, sojov\u00fd) a methanol.

K tomu lze pou\u017e\u00edt mechanick\u00e9 m\u00edchadlo.<\/p>\n

Proces transesterifikace<\/h3>\n

Transesterifikace je chemick\u00e1 reakce, p\u0159i kter\u00e9 se triglyceridy v rostlinn\u00e9m oleji reaguj\u00ed s methanolem za p\u0159\u00edtomnosti katalyz\u00e1toru (hydroxid sodn\u00fd). Reakce je exotermn\u00ed, tj. uvol\u0148uje teplo. Je d\u016fle\u017eit\u00e9 udr\u017eovat optim\u00e1ln\u00ed teplotu reakce (cca 50-60 \u00b0C) a pe\u010dliv\u011b dodr\u017eovat pom\u011br surovin. Po dokon\u010den\u00ed reakce (obvykle trv\u00e1 n\u011bkolik hodin) je nutn\u00e9 odd\u011blit glycerin (vedlej\u0161\u00ed produkt) od biodieselu. To se prov\u00e1d\u00ed decantac\u00ed nebo centrifugac\u00ed.<\/p>\n

\u010ci\u0161t\u011bn\u00ed a fin\u00e1ln\u00ed \u00faprava<\/h3>\n

Po odd\u011blen\u00ed glycerinu je biodiesel nutn\u00e9 propl\u00e1chnout vodou, aby se odstranily zbytky methanolov\u00e9 f\u00e1ze a katalyz\u00e1toru. N\u00e1sledn\u011b se biodiesel nech\u00e1 usadit a zfiltruje se, aby se odstranily p\u0159\u00edpadn\u00e9 zbytky ne\u010distot. Kvalita fin\u00e1ln\u00edho produktu se m\u016f\u017ee d\u00e1le zlep\u0161it pou\u017eit\u00edm filtr\u016f s jemn\u011bj\u0161\u00edmi p\u00f3ry. P\u0159ed pou\u017eit\u00edm je vhodn\u00e9 ov\u011b\u0159it vlastnosti biodieselu, jako je nap\u0159\u00edklad cetanov\u00e9 \u010d\u00edslo a viskozita.<\/p>\n

P\u0159i pr\u00e1ci s methanolem a hydroxidem sodn\u00fdm je nezbytn\u00e9 dodr\u017eovat p\u0159\u00edsn\u00e1 bezpe\u010dnostn\u00ed opat\u0159en\u00ed. Methanol je jedovat\u00fd a ho\u0159lav\u00fd, a proto je nutn\u00e9 pracovat v dob\u0159e v\u011btran\u00e9m prostoru a pou\u017e\u00edvat ochrann\u00e9 pom\u016fcky, jako jsou rukavice, br\u00fdle a respir\u00e1tor. Hydroxid sodn\u00fd je \u017e\u00edravina a m\u016f\u017ee zp\u016fsobit pop\u00e1leniny. P\u0159i pr\u00e1ci s n\u00edm je nutn\u00e9 db\u00e1t maxim\u00e1ln\u00ed opatrnosti.<\/p>\n
