Kushandiswa kweZinc Chloride muActivated Carbon Activation

Akabatwa kabhoni, inozivikanwa nehukuru hwayo hwepamusoro uye kugona kwayo kupinza mvura mumuviri, yakagadzira nzvimbo yakakura mumaindasitiri akasiyana-siyana. Mashandisirwo ayo anosanganisira kuchenesa mvura nekusefa mhepo kusvika pakubatsira kugadzira makemikari uye kuchengetedza simba. Imwe yenzira dzakasiyana-siyana dzekugadzirisa dzinoshandiswa kuvandudza hunhu hwe Yakagadziriswa kabhoni, kushandiswa kwe Zinc chloride yave nzira inoshanda zvikuru. Chinyorwa ichi cheblog chine chinangwa chekuongorora zvizere kuti zinc chloride inoshandiswa sei mukuita kuti Yakagadziriswa Carbon, tichiongorora nzira dzayo, maitiro ekuita kuti ishande, mabhenefiti ayo, nematambudziko anoenderana nayo.

Iyo Activation Mechanism yeZinc Chloride

Iyo activation process inosanganisira zinc chloride inovhurika kuburikidza nekubatana kwemuviri uye kemikari zviitiko. Kana zinc chloride ichishanda semumiriri, inobata necarbonaceous precursor zvinhu pane tembiricha yakakwira. Pane imwe molecular level, zinc chloride inoshanda seye dehydrating agent, ichibvisa mamorekuru emvura kubva kune inotangira. Uku kupera kwemvura kunotanga kuparara kwezvinhu zvakasikwa, zvichikonzera kuumbwa kwepores mukati me carbon structure.

Kemikari, zinc chloride inoshanda seinokonzeresa kurongekazve kwekabhoni maatomu, inosimudzira kuvandudzwa kweyakanyanya kurongeka uye porous kabhoni network. Sezvo tembiricha inokwira, zinc chloride inonyunguduka uye inopinda mu precursor, ichiwedzera zvakanyanya nzvimbo yekubatana pakati peiyo activating agent uye carbonaceous material. Uku kupindirana kwakakwenenzverwa kunogonesa kuita kwakanyatsoita activation process, ichipa kune hierarchical pore chimiro chinosanganisira micropores, mesopores, uye dzimwe nguva macropores. Kuvepo kweaya akasiyana saizi pore kwakakosha zvakanyanya, sezvo ichipa iyo activated kabhoni nekugona kushambadza yakafara spectrum yemamorekuru, zvinoenderana nehukuru hwavo uye maitiro.

The Activation Process

Maitiro ekushandisa zinc chloride ane matanho akati wandei akatevedzana. Pakutanga, zvinhu zvinogadzira kabhoni, zvinogona kusiyana kubva pamatanda ne Kozi Shells kusvika kumalahle, anopwanywa uye anokura kusvika pachiyero chakakodzera. Zvadaro, ma precursors aya anonyudzwa mu zinc chloride solution, maitiro anozivikanwa se impregnation. Impregnation ratio, iyo inomiririra huwandu hwe zinc chloride kune chinhu chinotangira, inodzorwa zvakanyatsonaka. Iyi impregnation ratio inokanganisa zvakanyanya hunhu hwekupedzisira hwe activated carbon; chiyero chepamusoro chinowanzo konzera chimiro che pore chakanyatsogadzirwa asi chinogonawo kukanganisa goho re activated carbon.

Kutevera impregnation, musanganiswa unoomeswa kuti ubvise chero hunyoro hwakawandisa. Iyo yakaomeswa zvinhu zvino inoiswa mukupisa kurapwa mukati memhepo inert, senge nitrogen kana argon. Iyi pyrolysis nhanho inoitika pakudziya kuri pakati pe400°C ne700°C. Munguva iyi yekupisa, zinc chloride inomutsa precursor zvinoenderana nematanho akatsanangurwa kare, zvichitungamira mukuumbwa kweiyo activated kabhoni. Post - pyrolysis, iyo ichangobva kuumbwa activated kabhoni inogeza zvakakwana kubvisa chero yasara zinc chloride. Iyi nhanho yekugeza yakakosha pakuona kuchena uye kushanda kwechigadzirwa chekupedzisira, sezvo chero yasara zinc chloride inogona kukanganisa kuita kweadsorption uye kuisa njodzi yekuchengetedza mune mamwe maapplication.

Zvakanakira Zinc Chloride Activation

Imwe yemabhenefiti akakosha ekushandisa zinc chloride mune activated kabhoni activation iri mune chaiyo kutonga kwainopa pamusoro peiyo pore chimiro. Nekugadzirisa maparamendi akadai seyero yekudzivirira uye activation tembiricha, vagadziri vanogona kugadzirisa iyo activated kabhoni kuti isangane nezvinodiwa chaizvo zvekushandisa kwakasiyana. Semuyenzaniso, mugasi adsorption maapplication uko kushambadza kwemamorekuru madiki kwakakosha, activated carbon ine high density ye micropores inogona kugadzirwa. Sezvineiwo, yemvura - chikamu adsorption, iyo yakabatidzwa kabhoni ine yakanyanya kuenzana pore chimiro, ine chikamu chakakura chemesopores, inowanzofarirwa.

Zinc chloride activation zvakare inozvirumbidza yakanyanyisa kushanda zvakanaka, zvichikonzera activated kabhoni ine yakakura nzvimbo uye yakakwira pore vhoriyamu. Izvi zvinoreva kuti zvishoma precursor zvinhu zvinogona kudiwa kugadzira activated kabhoni ine inodiwa maitiro kana ichienzaniswa nedzimwe nzira dzekuita. Uyezve, maitiro acho ari kukurumidza, kuderedza nguva yekugadzira uye mari yakabatana. Pamusoro pezvo, zinc chloride inowanikwa zvakanyanya uye inodhura - inoshanda, ichiita kuti iyo yese activation process ishande mune zvehupfumi, kunyanya kune yakakura-yekugadzira mashandiro.

Matambudziko Angangoitika uye Mhinduro

Pasinei nezvakawanda zvakanaka, zinc chloride activation haina matambudziko ayo. Chimwe chezvinonyanya kunetsa ndechekukanganisa kwayo kwezvakatipoteredza. Zinc chloride ikemikari ine ngozi, uye kuraswa zvisina kunaka kwetsvina inogadzirwa panguva yekuita activation, kunyanya yekugezesa mvura ine yakasara zinc chloride, inogona kutungamira mukusvibiswa kwevhu nemvura. Kudzikamisa nyaya iyi, matekinoroji epamusoro ekuchenesa mvura yetsvina, akadai sekunaya kwemakemikari uye ion exchange, anogona kuitwa kubvisa zinc ions kubva mumvura ine tsvina isati yabuda. Kudzokorodza uye kushandisa zvakare zinc chloride mhinduro inogona zvakare kubatsira kudzikisa nharaunda tsoka uku uchidzikisa mutengo wekugadzira.

Rimwe dambudziko rine chekuita nekutonga kwemhando yechigadzirwa chekupedzisira. Kubviswa kusina kukwana kweyasara zinc chloride kunogona kukonzera ngura mune mamwe maapplication uye kukanganisa maitiro ekushambadza. Matanho akasimba ekudzora emhando yakakosha, kusanganisira kuongororwa nguva dzose kweiyo activated kabhoni yezvasara zinc zvemukati uchishandisa hunyanzvi hwekuita seatomic absorption spectroscopy (AAS) kana inductively yakasanganiswa plasma - optical emission spectroscopy (ICP - OES). Pamusoro pezvo, kukwenenzvera nzira yekuwachira, senge kuwedzera huwandu hwematanho ekugeza kana kushandisa akakodzera ekugezesa maajenti, anogona kuwedzera kubviswa kwakasara zinc chloride uye kuve nechokwadi chemhando yechigadzirwa.

Mukupedzisa, zinc chloride inoita basa rinokosha mukuita activated kabhoni, ichipa mabhenefiti akasiyana maererano nepore chimiro chekugadzirisa, activation inoshanda, uye mutengo - kushanda. Nekudaro, kugadzirisa zvakabatana kwezvakatipoteredza uye mhando - zvipingamupinyi zvekudzora kwakakosha kune inogoneka uye inoshanda kugadzirwa kweyepamusoro-mhando activated kabhoni. Sezvo kudiwa kweiyo activated kabhoni kuri kuramba kuchikura munzvimbo dzakasiyana siyana, tsvakiridzo yeramangwana uye kuedza kwekusimudzira mu zinc chloride - yakavakirwa activation maitiro angangotarisa pakuwedzera kusimudzira kwezvakatipoteredza uye kuwedzera kunaka kwechigadzirwa.
