Izici ze-particulate catalysts
Ama-catalyst athile anendawo ethile ephezulu kanye ne-porosity, athuthukisa kakhulu ukusebenza kahle kokusabela. I-methanol yethu-kuya{2}}kuma-aromatics catalysts kanye nama-hydrogenation catalysts wonke aklanywe ngendlela eyizinhlayiya, abonisa ukuzinza okuhle kakhulu nokukhetha. Phakathi kwazo, imikhiqizo ye-zeolite ye-molecular sieve ibuye ibe nama-topology ahlukile njenge-FAU/MWW.
Ama-catalyst ezinhlayiyana ayikilasi elibalulekile lezinto ezisetshenziswa kakhulu emikhakheni yamakhemikhali, emvelo, kanye namandla. I-particle morphology yabo eyingqayizivele nokusebenza kwe-catalytic kubenza babe ingxenye ebalulekile ezinqubweni eziningi zezimboni. Ukusetshenziswa kwama-catalyst ezinhlayiyana kusekelwe ikakhulukazi endaweni yawo ephezulu ethize, ukuhlakazeka okuhle, nomsebenzi we-catalytic, onganciphisa kakhulu amandla okuqalisa futhi kuthuthukise izinga lokusabela nokukhetha ekuphenduleni kwamakhemikhali.
Umsebenzi we-catalytic wama-catalyst ezinhlayiya ikakhulukazi usuka kumasayithi awo asebenzayo. Lawa masayithi angakwazi ukukhangisa ama-molecule asabelayo, akhuthaze ukuphuka nokwakheka kwamabhondi amakhemikhali. Idizayini yezinhlayiya ayikhulisi nje kuphela indawo yokuxhumana phakathi kwe-catalyst nama-reactants kodwa futhi yenza kube lula ukugeleza nokuhlakazeka ku-reactor, ithuthukise ukusebenza kahle kokudlulisa okukhulu. Ngaphezu kwalokho, ama-catalyst ezinhlayiyana ngokuvamile anamandla amakhulu emishini, amelana nokuguga komzimba nokugqwala kwamakhemikhali phakathi nenqubo yokusabela, anweba impilo yawo yesevisi.
