Thaum lub sij hawm pub mis, cov khoom thiab cov kua ua kua uas tsis yog hydrogen yuav tsum tau hnov mob. Kev sib ntxiv ntawm cov ntaub ntawv ua kua yog tswj tau, uas kuj yog cov txheej txheem tshuaj zoo.

Ib Batch Intermittent

Cov txheej txheem kev tsim tshuaj lom neeg feem ntau yog kev tsim khoom tas mus li, thaum cov txheej txheem ntawm cov kws tshuaj intermediates feem ntau yog ib qho kev sib tshuam ntau lawm. Kev tsim khoom ib leeg yuav tsum tau rov ua ua ntej thiab tom qab ua tiav, thiab cov txheej txheem no yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm Kev Tsim Khoom Zoo rau Cov Khoom Siv Tshuaj. Nyob rau hauv ib tug tas mus li txheej txheem, raw cov ntaub ntawv hla tsis tu ncua los ntawm ib tug txheej ntawm cov khoom tshwj xeeb.

Txhua daim ntawm cov cuab yeej ua haujlwm hauv lub xeev khov kho, tsuas yog ua cov haujlwm tshwj xeeb, thiab cov khoom kawg yog cov khoom tso tawm hauv qhov nruam. Kev tsim khoom tsis sib xws yog hais txog kev ua cov khoom siv raw raws li cov txheej txheem ua ntu zus thiab kev ua haujlwm, thiab tsim cov khoom lag luam tsawg. Qhov xwm ntawm batch txheej txheem yog dynamic, nrog rau kev khiav hauj lwm tej yam kev mob thiab cov khoom zoo hloov lub sij hawm.

Multifunctional Khoom

Reactors nyob rau hauv zus tau tej cov tshuaj intermediates feem ntau yuav tsum tau ua kom tiav multi-kauj ruam cov tshuaj tiv thaiv los yog ntau yam txheej txheem. Cov theem sib txawv yuav tsum muaj kev tswj qhov kub thiab txias los yog tswj siab. Txhawm rau kom ua tiav kev tswj hwm ntawm cov txheej txheem no, ntau yam yuav tsum tau xav txog thaum tsim cov txheej txheem tswj thiab xaiv cov cuab yeej.

Kev lag luam kws tshuaj tam sim no dominates daim ntawv thov batch reactor. Reactors nrog stirrers yog tsim rau feem ntau chav ua haujlwm hauv kev lag luam tshuaj, xws li tshuaj tiv thaiv, rho tawm, distillation, thiab crystallizations. Kev tsim cov txheej txheem batch xav tau kev txiav txim siab ntau dua. Txoj kev ua haujlwm tas mus li muab txoj hauv kev zoom ntau dua thiab qee qhov kev ua haujlwm ntxiv. Cov txiaj ntsig zoo no tau coj ntau thiab ntau lub tuam txhab kws tshuaj los siv kev ua haujlwm tas li raws li txoj hauv kev tshiab rau kev tsim cov tshuaj intermediates thiab cov khoom xyaw tshuaj nquag.

Q: Dab tsi yog ethyl tert-butyl ether siv rau?

A: Ethyl tertiary-butyl ether (ETBE), tseem hu ua ethyl tert-butyl ether, feem ntau yog siv los ua oxygenate roj av additive hauv kev tsim cov roj av los ntawm cov roj crude. ETBE muaj kev sib npaug lossis ntau dua cov txiaj ntsig huab cua zoo dua li ethanol, thaum ua haujlwm thiab logistically nyuaj nyuaj.

Q: Kev siv ETBE yog dab tsi?

A: ETBE yog ib qho oxygenate siv los ua cov roj av sib xyaw kom ntxiv octane. ETBE yog tsim los ntawm kev sib txuas ntawm isobutylene nrog ethanol (feem ntau bio-ethanol kom tau txais cov qhab nia biofuel muaj nyob hauv ntau lub teb chaws) los ntawm kev ua kom sov rau lawv ua ke dhau lub catalyst.
