Isiphumo kunye nomsebenzi we-agent ye-template kwi-synthesis ye-ZSM ye-molecular sieve

Kwinkqubo ye-molecular sieve synthesis, i-agent ye-template idlala indima ebalulekileyo.I-agent ye-template yi-molecule ye-organic engakwazi ukukhokela ukukhula kwe-crystal ye-molecular sieve ngokusebenzisa i-intermolecular interaction kwaye inqume isakhiwo sayo sokugqibela se-crystal.
Okokuqala, i-agent ye-template inokuchaphazela inkqubo ye-synthesis ye-molecular sieve.Kwinkqubo ye-synthesis ye-molecular sieve, i-agent ye-template ingasetyenziselwa "njengesikhokelo" sokunceda ukudibanisa i-molecular sieve kunye nobukhulu obuthile bepore kunye nokuma.Oku kungenxa yokuba i-ejenti yetemplate iyakwazi ukuqaphela kunye nokulungelelanisa kwiintlobo ezithile ze-silicate ze-inorganic, ngaloo ndlela zilawula indlela yazo yokukhula kunye nesantya.Okwesibini, i-agent ye-template inokuchaphazela ubungakanani bepore kunye nokuma kwe-molecular sieve.
Iisefu zemolekyuli ezinobukhulu obuhlukeneyo kunye neemilo zinokudityaniswa kunye neearhente ezahlukeneyo zetemplate, kuba ubungakanani bemolekyuli kunye nemilo ye-arhente yetemplate imisela ubungakanani bepore kunye nokumila kwesihluzo sokugqibela semolekyuli.
Ngokomzekelo, i-template ye-decyl ingasetyenziselwa ukudibanisa i-ZSM-5 i-molecular sieve kunye nesakhiwo se-cyclopore esinamalungu alishumi, ngelixa i-template ye-dodecyl ingasetyenziselwa ukudibanisa i-molecular sieve ye-ZSM-12 kunye nesakhiwo se-cyclopore esinamalungu alishumi elinambini.
Ukongezelela, i-agent ye-template inokuchaphazela i-acidity kunye nokuzinza kwe-molecular sieve.Iindidi ezahlukeneyo zee-agent ze-template zinokunika i-asidi ehlukeneyo kwi-molecular sieve, kuba i-agent ye-template inokunxibelelana neziko le-acidic ye-molecular sieve ngokusebenzisa amaqela ayo asebenzayo.
Ngexesha elifanayo, ii-agent ze-template ezahlukeneyo zinokuchaphazela ukuzinza kwe-thermal kunye nokuzinza kwe-hydrothermal ye-molecular sieve.Ngokomzekelo, ukusetyenziswa kwe-template ye-amide kunokuphucula kakhulu ukuzinza kwe-thermal ye-ZSM-5 ye-molecular sieves.
Ekugqibeleni, i-agent ye-template idlala indima ebalulekileyo kwi-synthesis ye-ZSM ye-molecular sieve.
Ngokukhetha i-arhente yetemplate efanelekileyo, iisefu zemolekyuli ezinobungakanani obuthile kunye nokumila kwepore, iasidi elungileyo kunye nozinzo zinokudityaniswa, ukuze kuhlangatyezwane ngcono neemfuno zeendlela ezahlukeneyo zokuphendula.
