I-Biodiesel evame ukukhiqizwa ku-batch reactors besebenzisa ukushisa nokuxuba umshini njengamandla okufaka amandla. Ukuhlanganiswa kwe-ultrasonic cavitational kuyinto okunye okusebenzayo kusho ukufeza ukuxuba okungcono ekusetshenzisweni kwe-biodiesel yezohwebo. I-cavitation ye-Ultrasonic inikeza amandla okusebenza okudingekile we-biodiesel transesterification yezimboni.

Ukuguqulwa kwe-Transesterification (ukuguqulwa kweMikhali kuya kwe-Biodiesel)

Ukukhiqiza i-biodiesel kusuka kumafutha yemifino (isb soy, i-canola, i-jatropha, imbewu ye-sunflower noma algae) noma amafutha ezilwane, kuhilela ukusekelwa phansi ukudluliselwa kwe-fatty acids nge methanol noma i-ethanol ukunikeza ama-methyl esters afanayo noma e-ethyl esters. I-Glycerin iyinqubo engavinjelwe yalokhu kuphendula.

Amafutha omifino njengamafutha ezilwane ayi-triglycerides akhiwa ngamaketanga amathathu ama-fatty acids ahlanganiswe i-molecule ye-glycerin. I-Triglycerides yi-esters. Ama-Esters ayi-acids, afana nama-fatty acids, ahlangene nokuphuza utshwala. I-glycerine (= glycerol) isilapho esindayo. Esikhathini sokuguqulwa kwezinqubo ze-triglyceride esters ziphendulwa zibe yi-alkyl esters (= biodiesel) besebenzisa i-catalyst (lye) nesiphuzo esiphuzayo, isib. I-methanol, eveza i-methyl esters biodiesel. I-methanol ithatha indawo ye-glycerin.

I-glycerine – isigaba esinzima kakhulu – izogoba phansi. Biodiesel – isigaba sokukhanya – iyahamba phezulu futhi ingahlukaniswa, isb by decanters noma centrifuges. Le nqubo yokuguqulwa ibizwa ngokuthi i-transesterification.

Ukuphendulela okujwayelekile kwe-esterification ku Ukubhekwa kwe-batch kuthatha kancane kancane, futhi ukuhlukaniswa kwesigaba se-glycerin kudla isikhathi, ngokuvamile kuthatha amahora angu-5 noma ngaphezulu.
