Konstrukce reaktoru<\/p>\n

Pro samotnou reakci transesterifikace, kter\u00e1 p\u0159em\u011bn\u00ed rostlinn\u00fd olej na biodiesel, je pot\u0159eba reaktor. Jednoduch\u00fd reaktor m\u016f\u017ee b\u00fdt vyroben z nerezov\u00e9 oceli, vhodn\u00e9 je pou\u017e\u00edt n\u00e1dobu s v\u00edkem a m\u00edsadlem.

Postup v\u00fdroby<\/p>\n

Postup v\u00fdroby biodieselu je pom\u011brn\u011b jednoduch\u00fd, ale vy\u017eaduje p\u0159esnost a dodr\u017eov\u00e1n\u00ed bezpe\u010dnostn\u00edch p\u0159edpis\u016f. Nejd\u0159\u00edve se p\u0159iprav\u00ed roztok hydroxidu sodn\u00e9ho v methanolu. Pak se tento roztok opatrn\u011b p\u0159id\u00e1 do rostlinn\u00e9ho oleje a d\u016fkladn\u011b se prom\u00edch\u00e1.

Pot\u00e9 je nutn\u00e9 sm\u011bs nechat odst\u00e1t, aby se odd\u011blila glycerolov\u00e1 f\u00e1ze od biodieselu. Biodiesel je pot\u00e9 nutn\u00e9 propl\u00e1chnout vodou a nechat ho usadit aby se odd\u011blila voda.<\/p>\n

Filtrace a \u010di\u0161t\u011bn\u00ed<\/p>\n

Po odd\u011blen\u00ed glycerolu je biodiesel nutn\u00e9 filtrovat, aby se odstranily p\u0159\u00edpadn\u00e9 ne\u010distoty. K tomu lze pou\u017e\u00edt pap\u00edrov\u00e9 filtry, l\u00e1tkov\u00e9 filtry nebo jemn\u00e9 s\u00edto. Kvalita filtrace ovliv\u0148uje kvalitu v\u00fdsledn\u00e9ho biodieselu. \u010ci\u0161t\u011bn\u00ed m\u016f\u017ee zahrnovat i dal\u0161\u00ed kroky, jako je nap\u0159\u00edklad odstra\u0148ov\u00e1n\u00ed vody, ale to vy\u017eaduje ji\u017e sofistikovan\u011bj\u0161\u00ed techniku.<\/p>\n

V\u00fdroba biodieselu doma nese rizika spojen\u00e1 s pou\u017e\u00edv\u00e1n\u00edm toxick\u00fdch a \u017e\u00edrav\u00fdch l\u00e1tek. Je nezbytn\u00e9 dodr\u017eovat v\u0161echny bezpe\u010dnostn\u00ed p\u0159edpisy, pou\u017e\u00edvat ochrann\u00e9 pom\u016fcky a pracovat v dob\u0159e v\u011btran\u00e9m prostoru. V p\u0159\u00edpad\u011b kontaktu s methanolem nebo hydroxidem sodn\u00fdm je nutn\u00e9 okam\u017eit\u011b vyhledat l\u00e9ka\u0159skou pomoc.<\/p>\n
