Tam sim no, tus kab mob ntsws tshiab mob ntsws muaj kev cuam tshuam loj heev rau kev lag luam thoob ntiaj teb thiab kev lag luam kev lag luam, kev hloov pauv loj hauv geopolitics, thiab ua rau muaj kev ruaj ntseg ntawm lub zog. Txoj kev loj hlob ntawm niaj hnub thee chemical kev lag luam hauv kuv lub teb chaws yog qhov tseem ceeb tshaj plaws.
Tsis ntev los no, Xie Kechang, tus thawj coj ntawm Tuam Tshoj Academy of Engineering thiab tus thawj coj ntawm Lub Chaw Haujlwm Tseem Ceeb ntawm Coal Science thiab Technology ntawm Ministry of Education ntawm Taiyuan University of Technology, tau sau ib tsab xov xwm hais tias kev lag luam thee niaj hnub no, yog ib feem tseem ceeb ntawm kev lag luam. Lub zog hluav taws xob, yuav tsum "txhim kho lub zog tsim hluav taws xob thiab kev siv hluav taws xob hloov pauv thiab tsim kom muaj cov pa roj carbon tsawg, kev nyab xeeb thiab siv hluav taws xob zoo" yog tag nrho cov lus qhia, thiab cov kev cai yooj yim ntawm "huv, qis-carbon, nyab xeeb thiab muaj txiaj ntsig" yog cov kev cai yooj yim rau kev txhim kho kev lag luam thee niaj hnub tshuaj lom neeg thaum lub sijhawm "14th Tsib Xyoo Plan". Lub hom phiaj "rau guarantees" xav kom lub zog muaj zog lav rau tag nrho kev tsim kho thiab kev ua neej nyob thiab kev rov qab los ntawm Tuam Tshoj txoj kev lag luam.
Lub tswv yim txoj hauj lwm ntawm kuv lub teb chaws txoj kev lag luam thee chemical tsis tau paub meej
Xie Kechang tau qhia tias tom qab xyoo ntawm txoj kev loj hlob, kuv lub teb chaws txoj kev lag luam thee niaj hnub tau ua tiav zoo. Ua ntej, tag nrho cov nplai yog nyob rau hauv pem hauv ntej ntawm lub ntiaj teb no, qhov thib ob, kev ua haujlwm theem ntawm kev ua qauv qhia lossis cov chaw tsim khoom tau raug txhim kho tas li, thiab qhov thib peb, feem ntau ntawm cov thev naus laus zis yog nyob rau theem thoob ntiaj teb qib siab lossis qib siab. Txawm li cas los xij, tseem muaj qee qhov txwv tsis pub muaj nyob rau hauv kev txhim kho cov thee niaj hnub tshuaj lom neeg kev lag luam hauv kuv lub teb chaws.
Lub tswv yim qhov chaw ntawm kev tsim kho kev lag luam tsis meej. Coal yog lub zog tseem ceeb ntawm Tuam Tshoj lub zog ntawm tus kheej txaus. Lub zej zog tsis muaj kev paub txog kev lag luam thee niaj hnub thiab tshuaj ntsuab high-end chemical kev lag luam uas tuaj yeem ua kom huv thiab ua haujlwm tau zoo, thiab ib nrab hloov kev lag luam petrochemical, thiab tom qab ntawd "de-coalization" thiab "smelling chemical discoloration" tshwm sim, uas ua rau Tuam Tshoj txoj kev lag luam thee chemical. strategically positioned Nws tsis tau paub meej thiab meej, uas tau ua rau kev hloov pauv txoj cai thiab kev xav tias kev lag luam tau caij "cov menyuam coaster".
Intrinsic deficencies cuam tshuam rau theem ntawm kev lag luam kev sib tw. Kev lag luam thee chemical nws tus kheej muaj kev siv hluav taws xob tsawg thiab kev hloov pauv kev ua haujlwm, thiab teeb meem kev tiv thaiv ib puag ncig los ntawm "peb qhov pov tseg", tshwj xeeb tshaj yog cov dej khib nyiab thee, yog qhov tseem ceeb; vim qhov tsis tseem ceeb ntawm kev hloov pauv hydrogen (hloov pauv) cov tshuaj tiv thaiv hauv cov thev naus laus zis niaj hnub thev naus laus zis, kev siv dej thiab cov pa roj carbon emissions siab; Vim yog cov khoom lag luam loj loj, kev txhim kho tsis txaus ntawm kev ua kom zoo, sib txawv, thiab cov khoom lag luam tshwj xeeb hauv qab, qhov sib piv zoo ntawm kev lag luam tsis pom tseeb, thiab kev sib tw tsis muaj zog; vim qhov sib txawv ntawm kev sib koom ua ke thev naus laus zis thiab kev tswj hwm kev tsim khoom, cov khoom lag luam tus nqi siab, thiab kev ua haujlwm tag nrho tseem yuav txhim kho thiab lwm yam.
Ib puag ncig sab nraud txwv kev tsim kho kev lag luam. Petroleum price and supply, product capacity and market, resource allocation and taxation, credit financing and return, Environmental peev thiab dej siv, tsev cog khoom roj thiab emission txo yog tag nrho cov sab nraud yam uas cuam tshuam rau kev loj hlob ntawm kuv lub teb chaws cov thee chemical kev lag luam. Cov xwm txheej ib leeg lossis cov ntsiab lus tseem ceeb hauv qee lub sijhawm thiab qee thaj tsam tsis tsuas yog txwv tsis pub muaj kev noj qab haus huv ntawm kev lag luam thee tshuaj, tab sis kuj txo qis kev pheej hmoo ntawm kev muaj peev xwm ntawm kev lag luam tsim.
Yuav tsum txhim kho kev lag luam efficiency thiab tiv thaiv kev pheej hmoo
Kev ruaj ntseg hluav taws xob yog qhov teeb meem tag nrho thiab cov tswv yim cuam tshuam nrog Tuam Tshoj txoj kev lag luam thiab kev loj hlob ntawm kev sib raug zoo. Tau ntsib nrog txoj kev loj hlob hauv tsev thiab thoob ntiaj teb ib puag ncig, Tuam Tshoj txoj kev tsim hluav taws xob huv yuav tsum muaj kev txhim kho kev ua haujlwm siab ntawm cov pa phem tshem tawm cov thev naus laus zis, ntau cov pa phem tswj kev tswj hwm thev naus laus zis, thiab kev kho dej khib nyiab. Zero-emission thev naus laus zis thiab "peb qhov pov tseg" kev siv thev naus laus zis, tso siab rau cov haujlwm ua qauv qhia kom ua tiav kev lag luam sai li sai tau, thiab tib lub sijhawm, raws li lub ntiaj teb ib puag ncig, dej ib puag ncig thiab av ib puag ncig muaj peev xwm, kev tshawb fawb siv thee-based. hluav taws xob chemical kev lag luam. Ntawm qhov tod tes, nws yog ib qho tsim nyog los tsim thiab txhim kho thee-raws li lub zog thiab tshuaj huv huv cov qauv tsim khoom thiab muaj feem xyuam nrog kev tiv thaiv ib puag ncig, txhim kho kev tswj hwm kev tsim khoom huv ntawm qhov kev pom zoo, kev saib xyuas tag nrho thiab kev soj ntsuam tom qab, qhia meej txog kev saib xyuas lub luag haujlwm, tsim kom muaj kev lav phib xaub, thiab qhia thiab tswj cov thee-raws li lub zog huv kev txhim kho ntawm kev lag luam tshuaj.
Xie Kechang tau hais tias nyob rau hauv cov nqe lus ntawm kev txhim kho cov pa roj carbon tsawg, nws yog ib qho tsim nyog yuav tsum tau qhia meej txog qhov kev lag luam thee-based hluav taws xob tshuaj lom neeg tuaj yeem ua tau thiab tsis ua rau cov pa roj carbon tsawg. Ntawm qhov tod tes, nws yog ib qho tsim nyog yuav tsum ua kom tag nrho cov txiaj ntsig zoo ntawm cov khoom muaj txiaj ntsig CO los ntawm cov khoom lag luam hauv cov txheej txheem ntawm cov thee-based zog tshuaj lom neeg kev lag luam thiab nquag tshawb CCUS thev naus laus zis. Kev xa tawm siab tshaj plaws ntawm kev ua haujlwm siab CCS thiab kev tshawb fawb thiab kev tsim kho ntawm CCUS technologies xws li CO dej nyab thiab CO-to-olefins los nthuav dav kev siv cov peev txheej CO; Ntawm qhov tod tes, nws tsis tuaj yeem "pov rau hauv tus nas" thiab tsis quav ntsej cov txheej txheem ntawm cov thee-based zog tshuaj lom neeg kev lag luam high-carbon, thiab inhibit Txoj kev loj hlob ntawm kev lag luam thee-based zog tshuaj lom neeg kev lag luam yuav tsum muaj kev cuam tshuam technologies kom tawg. los ntawm lub bottleneck ntawm emission txo nyob rau hauv qhov chaw thiab lub zog txuag thiab efficiency txhim kho, thiab tsis muaj zog cov pa roj carbon ntau yam ntawm thee-based zog tshuaj lom neeg kev lag luam.
Hais txog kev txhim kho kev nyab xeeb, tsoomfwv yuav tsum qhia meej txog qhov tseem ceeb ntawm kev lag luam thiab kev lag luam ntawm cov tshuaj siv hluav taws xob raws li "ballast pob zeb" rau kuv lub teb chaws lub zog ruaj ntseg, thiab mob siab rau ua kom huv thiab muaj txiaj ntsig kev txhim kho thiab kev siv cov thee raws li lub hauv paus thiab lub luag haujlwm tseem ceeb ntawm kev hloov hluav taws xob thiab kev loj hlob. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los ua tus tsim cov thee-raws li lub zog thiab tshuaj lom neeg txoj kev npaj kev tsim kho, coj kev cuam tshuam kev tsim kho thev naus laus zis, thiab kev tswj hwm kev lag luam thee-based zog thiab tshuaj lom neeg kev lag luam kom maj mam ua tiav kev ua qauv qhia, kev lag luam nruab nrab thiab kev lag luam tag nrho; tsim kom muaj kev lav paub txog kev lag luam thiab nyiaj txiag txoj cai los txhim kho Kev lag luam thiab kev sib tw ntawm cov lag luam, tsim cov peev txheej ntawm cov roj thiab roj hluav taws xob hloov pauv, thiab tsim kom muaj ib puag ncig zoo rau kev txhim kho kev lag luam niaj hnub thee.
Nyob rau hauv cov nqe lus ntawm high-efficiency txoj kev loj hlob, nws yog ib qho tsim nyog yuav tsum nquag ua cov kev tshawb fawb thiab kev lag luam daim ntawv thov ntawm high-efficiency thee-raws li lub zog tshuaj technology xws li ncaj qha synthesis ntawm olefins / aromatics, thee pyrolysis thiab gasification kev koom ua ke, thiab paub breakthroughs nyob rau hauv lub zog. txuag thiab txo kev noj; nquag txhawb kev lag luam thee-raws li hluav taws xob tshuaj lom neeg kev lag luam thiab Kev sib koom ua ke ntawm kev tsim hluav taws xob thiab lwm yam kev lag luam, txuas ntxiv rau kev lag luam, tsim cov khoom siv high-end, cov yam ntxwv, thiab cov tshuaj muaj txiaj ntsig zoo, thiab kev txhim kho kev lag luam, kev pheej hmoo thiab kev sib tw; Ua kom tob txog kev tswj hwm lub zog txuag lub peev xwm, tsom mus rau kev txhawb nqa ntau yam ntawm kev txuag hluav taws xob xws li cov thev naus laus zis thev naus laus zis thev naus laus zis thev naus laus zis, thee-txuag thiab dej-txuag thev naus laus zis, txhim kho cov txheej txheem thev naus laus zis, thiab txhim kho cov khoom siv hluav taws xob siv hluav taws xob.
