P\u0159\u00edprava konopn\u00e9ho oleje<\/h3>\n

Z\u00e1kladem v\u00fdroby biodieselu je kvalitn\u00ed konopn\u00fd olej. Ten se z\u00edsk\u00e1v\u00e1 lisov\u00e1n\u00edm semen konop\u00ed. Kvalita oleje ovliv\u0148uje fin\u00e1ln\u00ed vlastnosti biodieselu. Ide\u00e1ln\u00ed je olej s n\u00edzk\u00fdm obsahem voln\u00fdch mastn\u00fdch kyselin a ne\u010distot. P\u0159ed samotnou v\u00fdrobou biodieselu je vhodn\u00e9 olej filtrovat, aby se odstranily p\u0159\u00edpadn\u00e9 zbytky semen nebo jin\u00fdch ne\u010distot.

Transesterifikace je chemick\u00fd proces, p\u0159i kter\u00e9m se triglyceridy v konopn\u00e9m oleji p\u0159em\u011b\u0148uj\u00ed na methylestery mastn\u00fdch kyselin (biodiesel) a glycerin.

Separace glycerin a \u010di\u0161t\u011bn\u00ed biodieselu<\/h3>\n

Po dokon\u010den\u00ed transesterifikace je nutn\u00e9 odd\u011blit glycerin od biodieselu. Glycerin, vedlej\u0161\u00ed produkt procesu, se usazuje na dn\u011b n\u00e1doby. Biodiesel se pot\u00e9 z horn\u00ed vrstvy od\u010derp\u00e1. Pro dosa\u017een\u00ed co nej\u010dist\u0161\u00edho biodieselu je nutn\u00e9 ho d\u00e1le \u010distit.

Kontrola kvality biodieselu<\/h3>\n

Kvalita vyroben\u00e9ho biodieselu se kontroluje pomoc\u00ed r\u016fzn\u00fdch test\u016f, kter\u00e9 ov\u011b\u0159uj\u00ed jeho vlastnosti, jako je nap\u0159\u00edklad cetanov\u00e9 \u010d\u00edslo, viskozita, obsah vody a voln\u00fdch mastn\u00fdch kyselin. Tyto testy jsou d\u016fle\u017eit\u00e9 pro zji\u0161t\u011bn\u00ed, zda biodiesel spl\u0148uje po\u017eadavky pro pou\u017eit\u00ed v dieselov\u00fdch motorech.<\/p>\n

Bezpe\u010dnostn\u00ed opat\u0159en\u00ed<\/h3>\n

V\u00fdroba biodieselu zahrnuje pr\u00e1ci s chemik\u00e1liemi, proto je nutn\u00e9 dodr\u017eovat p\u0159\u00edsn\u00e1 bezpe\u010dnostn\u00ed opat\u0159en\u00ed.
