Proces transesterifikace<\/p>\n

Transesterifikace je chemick\u00e1 reakce, p\u0159i kter\u00e9 se triglyceridy v rostlinn\u00e9m oleji reaguj\u00ed s alkoholem (nej\u010dast\u011bji methanolem) za p\u0159\u00edtomnosti katalyz\u00e1toru (obvykle hydroxidu sodn\u00e9ho nebo draseln\u00e9ho). Tato reakce produkuje methylestery mastn\u00fdch kyselin (biodiesel) a glycerol jako vedlej\u0161\u00ed produkt. Reakce prob\u00edh\u00e1 za specifick\u00fdch teplotn\u00edch a tlakov\u00fdch podm\u00ednek. D\u016fle\u017eit\u00e9 je udr\u017eovat spr\u00e1vn\u00fd pom\u011br mezi olejem, alkoholem a katalyz\u00e1torem.<\/p>\n

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

Po transesterifikaci je nutn\u00e9 odd\u011blit biodiesel od glycerolu a zbavit jej zbytk\u016f katalyz\u00e1toru a dal\u0161\u00edch ne\u010distot. To se prov\u00e1d\u00ed obvykle promyt\u00edm vodou a n\u00e1slednou filtrac\u00ed. Kvalita \u010di\u0161t\u011bn\u00ed je rozhoduj\u00edc\u00ed pro \u017eivotnost motoru a jeho v\u00fdkon. Ne\u010distoty mohou zp\u016fsobit korozi a zanesen\u00ed palivov\u00e9ho syst\u00e9mu.<\/p>\n

Su\u0161en\u00ed a fin\u00e1ln\u00ed kontrola<\/p>\n

P\u0159ed pou\u017eit\u00edm je nezbytn\u00e9 biodiesel d\u016fkladn\u011b vysu\u0161it, aby se odstranila zb\u00fdvaj\u00edc\u00ed voda. Voda m\u016f\u017ee zp\u016fsobit probl\u00e9my s uskladn\u011bn\u00edm a spalov\u00e1n\u00edm. N\u00e1sledn\u011b se provede fin\u00e1ln\u00ed kontrola kvality biodiesely, kter\u00e1 zahrnuje m\u011b\u0159en\u00ed parametr\u016f jako je viskozita, kyselost a obsah vody. Tyto parametry mus\u00ed spl\u0148ovat normy pro palivov\u00e9 biodiesely.<\/p>\n

Methanol je toxick\u00fd a ho\u0159lav\u00fd, 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.
