Environmental Issues nyob rau hauv Traditional Phenol Manufacturing
Tsoos phenol ntau lawm vam khom rau cov peev txheej petrochemical, nrog rau nws cov txheej txheem ua rau muaj teeb meem loj rau ib puag ncig: Cov pa phem emissions:
Kev sib xyaw ua ke siv benzene thiab acetone ua cov khoom siv raw tsim cov dej khib nyiab uas muaj benzene, phenolic tebchaw, thiab lwm yam khoom tsis zoo, ncaj qha kis cov dej hauv lub cev thiab av. Lub caij no, nws tso tawm ntau cov pa roj carbon dioxide thiab lwm cov pa hauv tsev cog khoom, ua rau lub ntiaj teb ua kom sov.
Kev Siv Khoom Siv: Cov tshuaj tiv thaiv yuav tsum muaj qhov kub thiab txias, ua rau muaj kev siv hluav taws xob ntau thiab siv cov khoom siv tsawg, ua rau cov khoom siv pov tseg.
Daim ntawv thov ntawm Niaj hnub nimno Environmental Protection Technologies
Kev tsim kho tshiab hauv Catalysis thiab Green Synthesis Technologies
Tshiab Catalytic Systems: Siv cov catalysts zoo (xws li, molecular sieves, ionic kua catalysts) txo cov tshuaj tiv thaiv kub thiab siab, txo qis zog noj thiab inhibiting los ntawm cov khoom tsim. Piv txwv li, titanium-silicon molecular sieves tuaj yeem txhim kho phenol synthesis efficiency ntau dua 30%.
Green Raw Material Hloov: Siv cov khoom siv bio-raws li raw khoom (xws li, lignin, straw hydrolysates) los yog cov khoom siv cog qoob loo (xws li, eugenol) ua cov substrates, phenol yog npaj los ntawm kev hloov pauv roj ntsha lossis tshuaj synthesis, txo kev cia siab ntawm cov khoom siv roj av.
Pollutant Treatment thiab Recycling Technologies
Nqus Gas Purification: Catalytic oxidation (xws li, TiO₂ photocatalysis, noble hlau catalysts) degrades volatile organic compounds (VOCs);
Txoj kev adsorption (activated carbon, molecular sieves) rov qab tau cov khoom muaj txiaj ntsig zoo li benzene los ntawm cov pa khib nyiab rau kev rov ua dua tshiab.
Kev kho dej khib nyiab:
Membrane cais technologies (rov qab osmosis, ultrafiltration) tshem tawm phenolic tshuaj los ntawm cov dej khib nyiab;
Advanced oxidation technologies (ozone oxidation, Fenton cov tshuaj tiv thaiv) ua kom cov pa phem ntau dhau, ua rau cov dej khib nyiab kom tau raws li cov qauv tso tawm lossis rov qab siv dua.
Cov Tswv Yim Txhim Kho Kom Zoo
Kev txo qhov peev txheej thiab kev ua kom zoo
Siv lub kaw lus kaw: Rov ua cov ntaub ntawv raw (xws li benzene, acetone) los ntawm cov dej khib nyiab thiab cov roj pov tseg kom ua tiav "zero paug";
Hloov cov txheej txheem batch nrog kev tsim khoom tas li kom txo tau lub zog siv thiab cov khoom poob.
Kev siv cov khoom siv rov ua dua tshiab thiab pov tseg
Kev Siv Cov Khoom Siv Khib Nyiab: Cov khoom siv hluav taws xob tau rov tsim dua los ua kom rov ua haujlwm lossis ua kom rov ua kom rov qab muaj zog cua sov; by-products (xws li, acetone) yog purified thiab reinvested nyob rau hauv ntau lawm.
Kev Siv Hluav Taws Xob Cascade: Siv cov tshuaj tiv thaiv pov tseg hluav taws xob rau kev tsim hluav taws xob lossis cua sov kom txo tau tag nrho cov nroj tsuag siv zog.
Kev tsim kho vaj huam sib luag Economy Models
Tsim kom muaj kev sib koom ua lag luam hauv chaw ua si: Ob peb phenol ntau lawm nrog downstream industries (xws li, plastics, resin processing) kom ua tiav lub voj voog kaw ntawm cov khoom siv raw-khoom-khoom pov tseg;
Koom tes nrog cov tuam txhab hluav taws xob los ntes thiab khaws cov pa roj carbon (CCUS) los ntawm cov pa roj carbon monoxide (xws li CO₂), txo cov pa roj carbon emissions.
Cov Lus Qhia Txog Kev Txhim Kho Yav Tom Ntej
Ua kom pom tseeb ntawm Technological Innovation
Biosynthesis Technologies: Tsim cov kab mob genetic engineered los ua ke phenol ncaj qha los ntawm cov suab thaj los ntawm fermentation, ua kom tag nrho bio-based ntau lawm;
Electrochemical thiab Photocatalytic Technologies: Tsav phenol synthesis siv lub zog tauj dua tshiab (hnub ci, hluav taws xob hluav taws xob) kom txo qis carbon emissions.
Txoj cai thiab kev sib koom ua lag luam
Kev koom tes thoob ntiaj teb txhawb nqa cov qauv kev sib koom ua ke thiab ua kom nrawm hla hla ciam teb ntawm cov txheej txheem tiv thaiv ib puag ncig (xws li, ntsuab catalysis, carbon footprint accounting txoj kev);
Tsoom fwv incentivize tuam txhab uas muag los txais yuav tsawg-carbon technologies los ntawm cov se incentives thiab carbon emission trading mechanisms, tsav tsheb kev lag luam ntsuab transformation.
Kev tsim kho kom ruaj khov hauv kev tsim phenol xav tau kev sib koom ua ke thev naus laus zis tshiab nrog cov tswv yim kev lag luam ncig. Los ntawm kev hloov kho catalytic, bio-raws li raw khoom hloov pauv, thiab kev kho cov pa phem hauv qhov tob, ib puag ncig lub nra tuaj yeem txo qis. Lub caij no, kev cia siab rau txoj cai txhawb nqa thiab kev koom tes hauv kev lag luam los tsim kom muaj "peev txheej-tsim-tso rov ua dua tshiab" kaw-voj yuav tsav kev lag luam mus rau qhov tsis muaj cov pa roj carbon tsawg, kev hloov pauv tau zoo, ua tiav qhov yeej-yeej rau kev lag luam thiab ib puag ncig.
