Wara na ol pipia i stap insait long ol 'solvent' em ol samting we i no gutpela long ol wok bilong indastri, na ol i mas rausim ol long rot bilong 'zeolite molecular sieves', we ol i kolim olsem 'solvent drying' o 'solvent treating'. Wantaim stretpela sais bilong ol hul na kemikel stebiliti bilong ol, ol 'molecular sieves' i kamap olsem ol samting we ol i no inap senisim na ol i gutpela tru long mekim wok long 'solvent', moa yet long ol gutpela kemikel na marasin indastri.
Ol hevi we i save kamap long solvent tritim
Ol indastrial solvent i save gat ol pipia, olsem planti wara (planti taim na i gat bikpela strong), ol samting i gat asid o alkali, ol samting i gat laip, na ol doti ges (kabon daioksait, naitrojen, na haidrokabon) we i save kamap bihain long ol i kisim bek solvent, na ol narapela samting.
Ol hevi bilong ol dispela wara na ol pipia long ol wok bilong indastri em (tasol i no inap long): bagarapim ol kemikel riaksen, bagarapim ol samting, kamapim hevi long envairomen na helt. Olsem na ol i mas rausim ol long inapim ol wok bilong proses, na long stopim ol hevi long kwaliti bilong prodak na risaikel bilong solvent.
Bilong Wanem Molecular Sieve I No Save Senisim?
Gutpela wok: Ol 'molecular sieves' i gat bikpela 'adsorption capacity' na 'adsorption rate', na dispela i mekim na ol i ken rausim wara long ol 'solvent' insait long sotpela taim, na dispela i mekim wok bilong draim i kamap gutpela moa.
Selektiviti: Ol 'molecular sieves' i save kisim ol 'impurity molecules' na i no save bagarapim ol narapela samting insait long 'solvent'. Dispela 'selective adsorption' samting i givim ol 'molecular sieves' ol gutpela samting long wok bilong tritim 'solvent'.
Stabiliti: Olsem wanpela gutpela samting bilong pulim wara, ol molekiul sif i soim bikpela 'thermal stability' na 'chemical stability', na ol i ken holim gutpela wok bilong pulim wara aninit long kain kain wok kondisen na 'kinetic circumstances'.
Rinewabiliti: Ol 'molecular sieves' em ol samting we i no bagarapim envairomen, na ol i ken stretim gut wok bilong ol long rot bilong 'regeneration', na dispela i larim ol i ken yusim gen na daunim ol kos bilong mani.
Ol Molekiul Sif Bilong Tritim Solvent
Type 3A Zeolite Molecular Sieve: Em i gutpela long draim ol liklik molekiul polar solvent olsem ethanol, methanol, acetone, DMF, THF, na ol narapela. Em i ken yusim tu long draim ol solvent olsem acetonitrile na 2-propanol.
Taip 4A Zeolite Molecular Sieve: Em i wanpela 'desiccant' we ol i save yusim planti taim na i no gat bikpela pe na i gat strongpela 'absorption capacity'. Em i gutpela long draim ol 'medium polar solvents' olsem 'chloroform', 'dichloromethane', 'ether', 'ethane' na ol narapela samting.
Type 5A Zeolite Molecular Sieve: Em inap long pulim wara, kabon daioksait, haidrojen salfaid, na ol liklik molekiul olsem ol 'linear alkanes'. Em i gutpela long tritim ol miks solvent, rausim ol 'polar impurities', na separetim ol 'hydrocarbon'.
Taip 13X Zeolite Molecular Sieve: Em i gat bikpela hul sais na bikpela adsorpsen kapasiti, na em i gutpela long polar na non-polar solvent tritmen. Planti taim ol i save yusim dispela marasin long rausim wara na ol pipia long ol samting olsem 'aromatic' na 'alkanes'.
