Z\u00edsk\u00e1n\u00ed oleje a p\u0159\u00edprava surovin<\/h3>\n

Z\u00e1kladn\u00ed surovinou pro v\u00fdrobu biodieselu B100 jsou rostlinn\u00e9 oleje nebo \u017eivo\u010di\u0161n\u00e9 tuky.

Transesterifikace \u2013 kl\u00ed\u010dov\u00fd krok v\u00fdroby<\/h3>\n

Transesterifikace je chemick\u00e1 reakce, p\u0159i kter\u00e9 se triglyceridy v oleji reaguj\u00ed s alkoholem (nej\u010dast\u011bji methanolem) za p\u0159\u00edtomnosti katalyz\u00e1toru (obvykle hydroxidu sodn\u00e9ho nebo draseln\u00e9ho).

Po transesterifikaci je nutn\u00e9 sm\u011bs neutralizovat a vy\u010distit.

Odstran\u011bn\u00ed vody a methanolu<\/h3>\n

Zbytkov\u00e1 voda a methanol v biodieselu mohou negativn\u011b ovlivnit jeho kvalitu a stabilitu. Proto je nutn\u00e9 je p\u0159ed fin\u00e1ln\u00edm zpracov\u00e1n\u00edm odstranit. To se obvykle prov\u00e1d\u00ed su\u0161en\u00edm a odpa\u0159ov\u00e1n\u00edm.<\/p>\n

Fin\u00e1ln\u00ed f\u00e1ze v\u00fdroby zahrnuje filtraci biodieselu, aby se odstranily ve\u0161ker\u00e9 zb\u00fdvaj\u00edc\u00ed ne\u010distoty. N\u00e1sleduje kontrola kvality, kter\u00e1 zahrnuje m\u011b\u0159en\u00ed viskozity, kyselosti a dal\u0161\u00edch parametr\u016f.

V\u00fdroba biodieselu B100 zahrnuje pr\u00e1ci s ho\u0159lav\u00fdmi l\u00e1tkami a \u017e\u00edrav\u00fdmi chemik\u00e1liemi. Je proto nezbytn\u00e9 dodr\u017eovat bezpe\u010dnostn\u00ed p\u0159edpisy a pou\u017e\u00edvat ochrann\u00e9 pom\u016fcky, jako jsou rukavice, br\u00fdle a ochrann\u00fd od\u011bv.
