Mvura netsvina dziripo muzvinonyungudutsa zvinhu zvisina kunaka mumaindasitiri, uye zvinoda kubviswa nezeolite molecular sieves, inozivikanwa sekuoma kwekunyungudutsa kana kugadzirisa zvinonyungudutsa. Nehukuru hwadzo chaihwo hwepore uye kugadzikana kwekemikari, masefa emamorekuru ave asingadzokerike uye anonyatso shanda zvinhu zvekugadzirisa zvinonyungudutsa, kunyanya mumaindasitiri emakemikari nemishonga.
Matambudziko Akajairika Mukugadzirisa Kurapa
Zvinyungudutsa zvemaindasitiri zvinowanzove netsvina, senge yakawandisa mvura (yakawanda uye inonyanya kupesvedzera), acidic kana alkaline zvinhu, organic zvinhu, uye kusachena magasi (carbon dioxide, nitrogen, uye hydrocarbons) akaunzwa mushure mekugadzirisa kupora, nezvimwe.
Kukanganisa kwemvura iyi netsvina pamaitiro emaindasitiri zvinosanganisira (asi kwete kugumira): kuvhiringa kuita kwemakemikari, kusvibisa zvinhu, kuunza njodzi dzezvakatipoteredza uye hutano. Saka dzinofanirwa kubviswa kuti dzigutse zvinodiwa pakuita, uye kudzivirira kukanganisa mumhando yechigadzirwa uye kudzokorodza kwezvinonyungudutsa.
Sei Molecular Sieve Isingadzoreki?
Kunyatsogona: Masefa emolecular ane yakanyanyisa adsorption kugona uye adsorption rate, achivagonesa kunyatsobvisa mvura kubva kune zvinonyungudutsa mukati menguva pfupi yenguva, uye nekudaro vachivandudza kuomesa.
Kusarudzika: Masefa mamorekuru anosarudza adsorb kusachena mamorekuru pasina kukanganisa zvakanyanya zvimwe zvikamu muzvinonyungudutsa. Iyi yakasarudzika adsorption pfuma inopa ma molecular sieves yakasarudzika mabhenefiti mune solvent kurapa maitiro.
Kugadzikana: Seyakanakisa adsorption zvinhu, ma molecular sieves anoratidza yakakwira kupisa kugadzikana uye kugadzikana kwemakemikari, uye anogona kuchengetedza yakagadzikana adsorption kuita pasi pemamiriro akasiyana ekushanda uye kinetic mamiriro.
Renewability: Masefa emolecular zvinhu zvine hushamwari kwezvakatipoteredza, uye kuita kwavo adsorption kunogona kudzoreredzwa kuburikidza nekuvandudza maitiro, zvichibvumira kudzokorodza uye nekudaro kuderedza mutengo wehupfumi.
Molecular Sieves For Solvent Kurapa
Nyora 3A Zeolite Molecular Sieve: Inokodzera kuomeswa diki molecule polar solvents akadai ethanol, methanol, acetone, DMF, THF, etc. Inogonawo kushandiswa kuomesa solvents akadai acetonitrile uye 2-propanol.
Nyora 4A Zeolite Molecular Sieve: Inonyanya kushandiswa uye inodhura-inoshanda desiccant ine simba rekusveta. Yakakodzera kuomesa svikiro polar solvents senge chloroform, dichloromethane, ether, ethane uye nezvimwe.
Tora 5A Zeolite Molecular Sieve: Inogona kutora mvura, carbon dioxide, hydrogen sulfide, uye mamorekuru madiki senge linear alkanes. Inokodzera kurapa zvakasanganiswa zvinonyungudutsa, kubvisa tsvina yepolar, uye kupatsanura mahydrocarbon.
Nyora 13x Zeolite Molecular Sieve: Ine saizi yakakura yepore uye yakakwira adsorption, uye inokodzera kurapa kwepolar uye isiri{0}}polar solvent. Inoshandiswa zvakanyanya kubvisa mvura netsvina kubva kune zvinonyungudutsa zvakaita seanonhuwirira uye alkanes.
