Hmoov Coke yog ib yam khoom tsim tawm hauv cov txheej txheem coking. Vim tias nws cov khoom me me dhau, thaum nws sib sau ua ke hauv lub cub tawg, cov cua ntws yuav tsis du, uas yuav cuam tshuam rau kev khiav ntawm cov khoom siv hauv lub cub tawg, thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov coke metallurgical. Vim tias hmoov coke muaj cov khoom ntawm cov pa roj carbon ntau, tsim cov qhov khoob sab hauv, thiab qee lub zog, cov kws tshawb fawb Suav tau ua kev tshawb fawb dav dav thiab tob txog yuav ua li cas siv hmoov coke hauv xyoo tas los no. HCMilling (Guilin Hongcheng) yog lub chaw tsim khoom ntawmcoke hlaulub tshuab sib tsooCov hauv qab no yog kev qhia txog kev siv lub tshuab sib tsoo metallurgical coke:

1. Cov pa roj carbon uas ua los ntawm cov hmoov sib tsoo coke hauv cov hlau: Cov pa roj carbon uas ua los ntawm cov hlau yog cov khoom siv carbon uas muaj cov qauv me me thiab muaj peev xwm nqus tau zoo. Nws siv dav hauv ntau qhov chaw xws li kev lag luam tshuaj lom neeg, kev ua zaub mov, kev tiv thaiv tub rog thiab kev lag luam tiv thaiv ib puag ncig. Kev ua tau zoo ntawm cov pa roj carbon uas ua los ntawm cov hlau yog cuam tshuam nrog nws thaj chaw tshwj xeeb, qhov ntim me me, qhov loj ntawm cov pa roj carbon uas faib tawm thiab cov tshuaj lom neeg. Tam sim no, cov khoom siv tseem ceeb rau kev npaj cov pa roj carbon uas ua los ntawm cov hlau hauv kuv lub tebchaws yog ntoo thiab thee. Nyob rau xyoo tas los no, vim muaj kev tsis txaus ntawm lub zog thiab lub tebchaws qhov kev tsom mus rau kev tiv thaiv ib puag ncig, tib neeg ib txwm nrhiav lwm cov khoom siv raw rau kev npaj cov pa roj carbon uas ua los ntawm cov hlau. Hmoov Coke yog cov khoom lag luam ntawm kev lag luam coking. Nws muaj cov pa roj carbon ruaj khov siab, cov pa roj volatile tsawg thiab cov tshauv, lub zog siab, thiab yooj yim nrhiav tau cov khoom siv raw. Nws yog cov khoom siv zoo heev rau kev npaj cov pa roj carbon uas ua los ntawm cov hlau. Tam sim no, cov pa roj carbon uas ua los ntawm cov hlau feem ntau yog tsim los ntawm kev kho cov hmoov coke los ntawm kev ua kom lub cev thiab kev ua kom tshuaj lom neeg. Txoj kev ua kom lub cev yuav tsum tau ua kom cov khoom siv raw yuav tsum tau carbonized ua ntej ua kom lub cev, thiab tom qab ntawd ua kom lub cev ntawm 600 txog 1200 ° C. Tus activator muaj cov pa roj oxidizing xws li CO2 thiab cov pa dej, thiab cov pa roj carbon atoms hauv cov pa roj oxidizing carbon oxide siv los hla dhau. Cov pa roj carbon activated nrog cov qhov hws zoo tsim los ntawm kev ua haujlwm ntawm kev qhib, nthuav dav thiab tsim cov qhov khoob tshiab. Kev ua kom tshuaj lom neeg yog hais txog kev sib xyaw cov khoom siv raw nrog cov activators (alkali hlau thiab alkali hlau hydroxides, inorganic ntsev thiab qee cov kua qaub) hauv qee qhov sib piv, muab tso rau hauv lawv rau ib lub sijhawm, thiab tom qab ntawd ua tiav cov kauj ruam carbonization thiab kev ua kom ua haujlwm hauv ib kauj ruam.

2. Kev kho dej khib nyiab biochemical los ntawm cov hmoov sib tsoo coke metallurgical: txoj kev adsorption yog ib txoj kev siv ntau los kho cov dej khib nyiab coking. Vim yog qhov tsim cov qhov khoob sab hauv ntawm cov hmoov coke thiab kev ua haujlwm adsorption zoo, qee tus kws tshawb fawb hauv Suav teb tau ua kev tshawb fawb txog kev kho cov dej khib nyiab coking. Zhang Jinyong siv cov hmoov coke uas ua haujlwm los ntawm cov pa dej kom nqus cov dej khib nyiab biochemical los ntawm cov nroj tsuag coking. Tom qab adsorption, qhov kev thov oxygen tshuaj lom neeg (COD) ntawm cov dej khib nyiab raug txo los ntawm 233mg / L mus rau 50mg / L, mus txog tus qauv tso tawm hauv tebchaws thawj chav kawm. Liu Xian et al. siv cov hmoov coke rau kev kho cov dej khib nyiab coking adsorption thib ob, thiab kawm txog cov txheej txheem tsim nyog rau cov dej khib nyiab coking adsorption los ntawm kev sim tas mus li thiab dynamic. Cov txiaj ntsig tshawb fawb qhia tau tias COD ntawm cov dej khib nyiab biochemical tom qab kev kho cov hmoov coke siab heev tuaj yeem txo qis dua 100mg / L, thiab tus nqi tshem tawm chromaticity tuaj yeem ncav cuag ntau dua 60%, uas ua tau raws li cov kev xav tau zoo ntawm cov tuam txhab coking.

3. Kev tsim cov hmoov coke sib tsoo metallurgical nrog cov khoom ntxiv: cov txheej txheem coke hmoov nws tus kheej tsis muaj kev nplaum, thiab nws feem ntau yog siv los ntawm kev ntxiv cov khoom sib txuas rau nws rau kev nias thiab tsim. Muaj ntau hom coke hmoov ntxiv, thiab qhov zoo ntawm coke tsim tawm tsis zoo ib yam. Liu Baoshan siv cov neeg sawv cev sib xyaw ntawm humate, cov hmoov txhuv nplej siab pov tseg, thee slime, caustic soda thiab bentonite ua cov khoom sib txuas los kawm txog qhov ntau ntawm cov khoom ntxiv, cov xwm txheej molding ntawm coke hmoov, cov duab thiab qhov loj me ntawm lub pob molding, thiab qhov kub thiab txias kom qhuav, thiab cov pob npaj tau sim thiab tua hluav taws, thiab cov txiaj ntsig tau qhia tias cov hmoov coke pob muaj lub zog zoo thiab thermal stability, thiab tuaj yeem siv los tsim cov roj artificially. Zhang Liqi siv cov hmoov coke thiab cov tar residue tsim los ntawm lub tshuab hluav taws xob roj los sib tov thiab duab raws li qee qhov sib piv, thiab tom qab ntawd oxidized thiab carbonized los ua coke rau gasification. Cov khoom ntawm coke tau mus txog tus qauv ntawm gasification coke. Nws muab lub hauv paus theoretical rau kev tsim khoom lag luam.

4. Cov hmoov sib tsoo coke metallurgical los tsim cov coke metallurgical: cov hmoov coke feem ntau yog siv los ua tus neeg sawv cev thinning hauv cov txheej txheem coking. Ntxiv cov hmoov coke tsim nyog hauv cov txheej txheem coking tuaj yeem txhim kho qhov zoo ntawm coke. Vim tias muaj kev tsis txaus ntawm cov peev txheej coking thee hauv Suav teb, txhawm rau nthuav cov peev txheej coking thee thiab txo tus nqi ntawm kev sib xyaw thee, ntau lub tuam txhab coking tau sim siv cov hmoov coke ua cov khoom sib xyaw thee rau coking los txhim kho cov txiaj ntsig kev lag luam ntawm cov hmoov coke. Ntau lub tuam txhab hauv Suav teb tau ua kev tshawb fawb txog qhov loj me thiab feem pua ​​ntawm cov hmoov coke. Yang Mingping tau ua qhov kev sim tsim khoom lag luam raws li qhov kev sim me me ntawm lub qhov cub coke. Cov txiaj ntsig qhia tau tias nyob rau hauv cov txheej txheem coking sab saud, nws muaj peev xwm ntxiv 3% txog 5% ntawm cov hmoov coke los hloov cov thee lean rau coking. Qhov degree thaiv nce ntxiv, thiab tus nqi pauv nyiaj nce ntxiv li 3%. Los ntawm kev tshawb fawb, Wang Dali et al. pom tias coking nrog cov hmoov coke tsis muaj qhov cuam tshuam rau qhov kev cuam tshuam siab tshaj plaws ntawm vitrinite ntawm cov thee sib xyaw. Txawm li cas los xij, los ntawm kev ntsuas me me, nws pom tias cov hmoov coke loj dua 0.2 hli tau ywj pheej hauv coke, thiab nws nyuaj rau kev koom ua ke nrog lwm cov khoom, thiab cov duab tsis hloov pauv; thaum cov hmoov coke me dua 0.2 hli tau yooj yim qhwv los ntawm colloid, uas yog qhov zoo rau kev tsim coke. Qhov feem pua ​​​​​​zoo tshaj plaws ntawm cov hmoov coke yog 1.0% -1.7%, qhov loj me ntawm cov khoom zoo tshaj plaws yog 98% -100% tsawg dua 3 hli, 78% -80% tsawg dua 1 hli, thiab 40% -50% tsawg dua 0.2 hli.

Kev sib tsoo coke metallurgical yog qhov tsis sib cais ntawm lub tshuab sib tsoo coke metallurgical. Ua tus tsim khoom ntawm lub tshuab sib tsoo coke metallurgical, HCMilling (Guilin Hongcheng) tsim tawmcoke hlau Raymondlub zeb, coke hlau zoo heevlub zeb, coke hlau ntsuglub menyuamlub zebthiab lwm yam khoom siv. Nws tuaj yeem tsim tau 80-2500 mesh metallurgical coke hmoov thiab muab kev txhawb nqa rau kev siv cov hmoov sib tsoo metallurgical coke.
