Tam sim no, cov kev tawm tshiab ntawm cov kabmob pneumonia muaj kev cuam tshuam loj heev rau kev lag luam thoob ntiaj teb thiab kev ua haujlwm ntawm nyiaj txiag, kev hloov pauv ntawm thaj chaw hauv cheeb tsam, thiab nce ntxiv rau kev ruaj ntseg ntawm lub zog. Kev tsim kho cov kev lag luam chemical chemical tshiab hauv kuv lub teb chaws yog lub tswv yim tseem ceeb.
Tsis ntev los no, Xie Kechang, tus thawj coj ntawm Tuam Tsev Tshawb Fawb ntawm Suav Academy thiab tus thawj coj ntawm Lub Chaw Ntsuas Hluav Taws Xob ntawm Thev Nthuav Hluav Taws Xob thiab thev naus laus zis ntawm Ministry of Education ntawm Taiyuan University of Technology, tau sau ib tsab xov xwm hais tias kev lag luam chemical chemical niaj hnub, yog ib feem tseem ceeb ntawm lub zog tsim hluav taws xob, yuav tsum "txhawb kev tsim hluav taws xob thiab kev siv hluav taws xob thiab tsim kom muaj cov roj carbon tsis huv, muaj kev nyab xeeb thiab txuag hluav taws xob" yog cov lus qhia tag nrho, thiab cov kev cai yooj yim ntawm "huv si, qis carbon, nyab xeeb thiab muaj txiaj ntsig" yog qhov yooj yim rau kev txhim kho qhov kev lag luam niaj hnub no kev lag luam chemical chemical ua haujlwm thaum "Phiaj Xwm Thib 5 Xyoo". Lub hom phiaj ntawm "6 qhov kev lees paub" yuav tsum tau muaj lub zog ua kom muaj zog loj rau tag nrho kev tsim kho tshiab thiab kev ua neej nyob thiab rov qab los ntawm Tuam Tshoj txoj kev lag luam.
Lub tswv yim muab tso rau ntawm kuv lub teb chaws cov chaw lag luam chemical tsis tau paub meej
Xie Kechang tau qhia tias tom qab xyoo ntawm txoj kev loj hlob, kuv lub teb chaws niaj hnub kev lag luam chemical chemical tau ua rau muaj kev vam meej. Ua ntej, tag nrho qhov ntsuas nyob hauv lub ntiaj teb, thib ob, theem kev ua haujlwm ntawm kev ua qauv qhia lossis cov chaw tsim khoom raug tsim kho tas li, thiab qhov thib peb, feem ntau ntawm cov thev naus laus zis yog nyob rau theem thoob ntiaj teb lossis qib siab. Txawm li cas los xij, tseem muaj qee qhov kev txwv nyob hauv kev txhim kho kev lag luam chemical chemical tshiab hauv kuv lub teb chaws.
Lub luag haujlwm xaiv tsa ntawm kev tsim kho kev lag luam tsis paub meej. Coal yog lub zog loj ntawm Tuam Tshoj lub zog hluav taws xob pab tus kheej. Lub zej zog tsis muaj kev paub txog kev lag luam chemical tshuaj lom neeg niaj hnub thiab kev lag luam chemical ntsuab high-kawg uas tuaj yeem huv thiab ua haujlwm tau zoo, thiab ib feem hloov kev lag luam petrochemical, thiab tom qab ntawd "de-coalization" thiab "ntxhiab tsw tshuaj lom" tshwm sim, uas ua rau Tuam Tshoj kev lag luam chemical tshuaj lom neeg Tus txheej txheem cim Nws tsis tau paub meej thiab meej, uas tau ua rau muaj kev hloov pauv txoj cai thiab kev xav tias cov lag luam tau caij "coaster".
Kev tsis txaus ntseeg cuam tshuam txog qib ntawm kev lag luam kev sib tw. Kev lag luam tshuaj lom neeg nws tus kheej muaj kev siv hluav taws xob tsawg thiab kev hloov pauv ntawm kev ua haujlwm, thiab kev tiv thaiv ib puag ncig teeb meem los ntawm "peb qhov" pov tseg, tshwj xeeb tshaj yog cov chemical chemical khib nyiab, yog qhov muaj koob npe nrov; vim tias qhov tsis txaus ntseeg kev hloov kho hydrogen (hloov dua siab tshiab) cov tshuaj tiv thaiv nyob rau hauv cov tshuab ua hluav taws xob tshiab niaj hnub, kev siv dej thiab cov pa roj carbon emissions yog qhov siab; Vim tias cov khoom lag luam ntau dhau los, kev txhim kho tsis txaus ntseeg ntawm qhov ua kom zoo, txawv txav, thiab cov khoom lag luam tshwj xeeb qis qis, qhov zoo sib piv ntawm kev lag luam tsis yooj yim pom, thiab kev sib tw tsis muaj zog; vim muaj qhov sib txawv hauv kev siv thev naus laus zis thiab kev tswj hwm kev tsim khoom, cov nqi khoom lag luam tau siab, thiab kev ua haujlwm tag nrho tseem yuav tsum tau Txhim Kho thiab lwm yam.
Qhov chaw sab nraud txwv kev tsim kho kev lag luam. Cov roj av nqe thiab muab khoom, peev xwm khoom lag luam thiab kev ua lag luam, kev faib nyiaj thiab kev sau se, kev them nuj nqi qiv nyiaj thiab xa rov qab, kev muaj peev xwm ib puag ncig thiab kev siv dej, tsev cog khoom roj thiab emission txo yog txhua yam sab nraud uas cuam tshuam rau kev txhim kho kev lag luam kev lag luam hauv kuv lub teb chaws. Ib qho los yog ib tus neeg muaj lub ntsiab nyob hauv qee lub sijhawm thiab qee thaj chaw tsis yog txwv tsis pub muaj kev noj qab haus huv zoo ntawm cov thee kev lag luam, tab sis kuj tseem txo cov nyiaj txiag kev lag luam tawm tsam kev pheej hmoo ntawm kev lag luam tsim.
Yuav tsum txhim kho kev lag luam kom tau txais txiaj ntsig thiab muaj peev xwm tiv thaiv kev pheej hmoo
Kev ruaj ntseg hluav taws xob yog qhov teeb meem tag nrho thiab cov tswv yim ntsig txog Tuam Tshoj txoj kev lag luam thiab kev txhim kho. Ntsib nrog txoj kev txhim kho ib puag ncig hauv tsev thiab thoob ntiaj teb, Tuam Tshoj txoj kev txhim kho kev siv hluav taws xob huv yuav tsum muaj kev nthuav dav ntawm cov cuab yeej ua kom muaj kuab paug pov tseg, ntau cov kuab paug tswj kev tswj cov thev naus laus zis, thiab kev kho dej tsis huv. Kev siv tshuab ua xoom thiab "peb pov tseg" kev siv cov khoom siv thev naus laus zis, tso siab rau cov phiaj xwm ua haujlwm kom ua tiav kev lag luam kom sai li sai tau, thiab tib lub sijhawm, raws li qhov chaw muaj huab cua ib puag ncig, dej ib puag ncig thiab cov av ib puag ncig muaj peev xwm, kev tshawb fawb tsim hluav taws xob lub zog tshuaj kev lag luam. Ntawm qhov tod tes, nws tsim nyog los tsim thiab txhim kho cov thee-zog ua haujlwm thiab cov qauv tshuaj lom neeg huv huv thiab cov cai tiv thaiv ib puag ncig, txhim kho huv kev tswj kev tsim cov txheej txheem kev pom zoo, kev saib xyuas tag nrho thiab kev soj ntsuam tom qab, qhia meej kev saib xyuas lub luag haujlwm, tsim lub luag haujlwm saib xyuas lub luag haujlwm, thiab qhia thiab tswj kev tsim hluav taws xob ua kom huv Kev tsim kho kev lag luam tshuaj lom neeg.
Xie Kechang tau taw qhia tias yog hais txog kev siv cov pa roj carbon monoxide qis, nws yog qhov yuav tsum tau hais kom meej meej tias cov thee-lub zog siv hluav taws xob kev lag luam muaj peev xwm thiab tsis ua dab tsi hauv kev txo carbon. Ntawm ib sab, nws yog qhov yuav tsum tau ua kom siv tag nrho cov txiaj ntsig ntawm qhov tseem ceeb ntawm high-concentration CO by-product nyob rau hauv cov txheej txheem ntawm cov thee-zog siv hluav taws xob tshuaj lom neeg kev lag luam thiab nquag tshawb nrhiav CCUS thev naus laus zis. Kev xa tawm ntawm CCS-ua haujlwm tau zoo thiab kev tshawb nrhiav qhov tseeb thiab kev tsim kho CCUS thev naus laus zis xws li CO dej nyab thiab CO-rau-olefins kom nthuav dav siv hluav taws xob CO; ntawm qhov tod tes, nws tsis tuaj yeem "muab pov rau hauv nas" thiab tsis quav ntsej cov txheej txheem cov txheej txheem ntawm cov pa roj carbon-zog lub zog cov pa roj carbon muaj kev lag luam siab, thiab kev cuam tshuam kev tsim kho ntawm kev tsim hluav taws xob-based zog kev lag luam chemical yuav tsum muaj kev cuam tshuam cov thev naus laus zis kom tawg. los ntawm kev ua haujlwm ntawm kev txo emission ntawm qhov chaw thiab lub zog txuag thiab kev ua haujlwm txhim kho kom zoo dua qub, thiab ua kom lub zog ntawm cov pa roj carbon ntau ntawm cov pa roj carbon zog-raws li kev lag luam chemical chemical.
Hais txog kev txhim kho kom muaj kev nyab xeeb, tsoomfwv yuav tsum qhia meej txog qhov tseem ceeb ntawm kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv roj av ua cov khoom siv roj ua "pob zeb" rau kuv lub tebchaw lub zog kev nyab xeeb, thiab kev ncaj ncees rau kev tsim kho kom huv thiab siv thiab ua cov thee li foothold thiab thawj lub luag haujlwm ntawm kev hloov kho lub zog thiab kev loj hlob. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los ua cov kev tsim qauv ntawm kev tsim hluav taws xob thiab kev tsim cov chemical kev cai, qhia kev cuam tshuam cov thev naus laus zis kev tsim kho tshiab, thiab kev txiav txim siab txhawb cov thee-raws li lub zog thiab tshuaj lag luam kom maj mam ua tiav kev ua qauv qhia, kev ua lag luam me thiab kev lag luam tag nrho; tsim kev lav phib xaub txog kev lag luam thiab nyiaj txiag los txhim kho Txhim kho Kev lag luam thiab kev sib tw ntawm cov lag luam, tsim cov nplai roj thiab roj av hloov chaw muaj peev xwm, thiab tsim ib puag ncig sab nraud zoo rau kev txhim kho kev lag luam tshuaj lom neeg ua lag luam niaj hnub no.
Hais txog kev ua haujlwm siab, nws yog ib qho tsim nyog yuav tsum tau ua tiav kev tshawb fawb thiab kev siv tshuab ntawm high-efficiency thee-raws li lub zog hluav taws xob cov tshuab siv hluav taws xob xws li kev sib txuas ncaj qha ntawm olefins / aromatics, thee pyrolysis thiab kev sib koom ua ke, thiab paub kev sib nkag siab hauv lub zog kev txuag thiab siv txo; siv zog txhawb kev lag luam tsim hluav taws xob ua kom muaj zog thiab Kev sib xyaw ua ke ntawm lub zog thiab lwm yam kev lag luam, txuas ntxiv mus rau cov saw hlau kev lag luam, tsim cov khoom lag luam siab, cov yam ntxwv, thiab cov tshuaj muaj txiaj ntsig zoo, thiab txhim kho kev lag luam zoo, kev pheej hmoo tiv thaiv thiab kev sib tw; tob zuj zus kev tswj hwm ntawm lub zog-txuag lub peev xwm, tsom mus rau kev txhawb nqa ntau lub zog ntawm cov thev naus laus zis xws li qib qis ntawm kev siv hluav taws xob, kev siv thee-txuag thiab txuag dej, txhim kho cov txheej txheem thev naus laus zis, thiab txhim kho kev siv hluav taws xob siv kom tau zoo.
