Hnub no, biodiesel yog feem ntau ua hauv batch reactors. Ultrasonic biodiesel ua pub rau kev nruam inline ua. Ultrasonication tuaj yeem ua tiav biodiesel tawm los dhau li ntawm 99%. Ultrasonic reactors txo cov sijhawm ua tiav los ntawm cov khoom siv 1 mus rau 4 teev cov txheej txheem ua kom tsawg dua 30 feeb. Tseem ceeb dua, ultrasonication txo lub sijhawm sib cais los ntawm 5 mus rau 10 teev (siv kev ntxhov siab) kom tsawg dua 60 feeb. Lub ultrasonication kuj tseem pab txo qis nyiaj kom tau catalyst kom yuav tsum tau txog li 50% vim tias muaj cov tshuaj lom neeg muaj zog nyob hauv qhov chaw muaj cavitation (saib sonochemistry). Thaum siv ultrasonication cov nyiaj ntau dhau ntawm cov methanol uas xav tau yog txo, ib yam nkaus. Lwm qhov txiaj ntsig yog qhov tshwm sim hauv kev coj dawb huv ntawm glycerin.
Ua ultrasonic ntawm biodiesel yuav cov kauj ruam hauv qab no:
1. cov roj zaub lossis tsiaj muaj roj cov roj tau sib xyaw nrog cov methanol (uas ua rau methyl esters) lossis ethanol (rau ethyl esters) thiab sodium los yog potassium methoxide lossis hydroxide
2. cov kev sib xyaw ua ke yog rhuab, piv txwv li mus rau qhov kub thiab txias ntawm 45 txog 65degC
3. cov sib xyaw ua kom sov yog tau sonicated inline rau 5 rau 15 vib nas this
4. glycerin ua poob tawm los yog sib cais siv centrifuges
5. qhov hloov pauv biodiesel yog ntxuav nrog dej
Feem ntau, qhov sonication tau ua ntawm qhov ntsuas kom siab (1 mus rau 3bar, siab ntsuas) siv lub twj tso kua mis pub thiab ib qho rov qab ntsuas-siab valve ib sab ntawm cov ndlwg ntawm tes.
Cov nqi ntawm Ultrasonic Biodiesel Raug
Ultrasonication yog cov txhais tau tias muaj txiaj ntsig los ua kom cov tshuaj tiv thaiv nrawm thiab hloov pauv hloov hauv kev lag luam biodiesel ua. Ultrasonic cov nqi ua feem ntau los ntawm kev nqis peev rau ultrasonic khoom, nqi hluav taws xob thiab txij nkawm. Kev txuag hluav taws xob zoo tshaj (nyem kab kos rau sab xis) ntawm Altrasonic ultrasonic cov khoom siv pab txo tus nqi hluav taws xob thiab ntawm qhov no yuav ua rau cov txheej txheem no tseem ntsuab dua. Cov nqi rau cov ultrasonication sib txawv ntawm 0.1ct thiab 1.0ct rau ib liv (0.4ct txog 1.9ct / gallon) thaum siv rau hauv cov kev lag luam nplai. Nyeem cov ntaub ntawv ntau ntxiv txog cov nqi tsim nqi ultrasonic.
