I-Hydrotreating iwuhlelo olubalulekile ekucwengisweni komkhiqizo we-petroleum, okuhloswe ngayo ukususa ukungcola kanye nokwenza ngcono izinga likaphethiloli. Ama-catalyst asetshenziswa ku-hydrotreating adlala indima ebalulekile ekwenzeni le nqubo ibe lula. Enye yezinhloso eziyinhloko ze-hydrotreating ukususa isulfure, i-nitrogen nokunye ukungcola ezingxenyeni ezihlukahlukene zikawoyela ongahluziwe, njenge-naphtha, i-vacuum gas oil (VGO) kanye nodizili. Lesi sihloko sizohlinzeka ngokubheka okujulile ngokubalulekai-hydrotreating catalysts, ikakhulukazi ku-hydrodesulfurization (HDS) ye-naphtha ne-VGO kanye ne-hydrodenitrification (HDN) kaphethiloli wedizili.
Ama-hydrotreating catalysts abalulekile enqubweni ye-hydrofinishing ngenxa yekhono lawo lokuguqula izinhlanganisela zesulfure ne-nitrogen ezingafuneki zibe izinhlobo zazo ze-hydrogen sulfide kanye ne-ammonia. Lokhu kuguqulwa kufinyelelwa ngochungechunge lwezimo eziphuthumayo ezenzeka ngaphansi kwezinga lokushisa eliphezulu nezimo zokucindezela okuphezulu. Ama-catalysts amabili aziwayo asetshenziswa ku-hydrotreating yiI-GC-HP406futhiI-GC-HP448, eziklanyelwe ngokukhethekile izingxenye ezahlukene zikawoyela ongahluziwe.
Endabeni ye-naphtha, i-hydrodesulfurization iyisinyathelo esibalulekile ekusetshenzisweni kwamanzi njengoba i-naphtha iwukudla okuyinhloko kokukhiqizwa kukaphethiloli. II-GC-HP406i-catalystyakhelwe ngokukhethekile ukukhuthaza ngempumelelo ukukhishwa kwezinhlanganisela zesulfure ku-naphtha, ukuqinisekisa ukuthi umkhiqizo wokugcina uhambisana nemithetho eqinile yezemvelo kanye nokucaciswa kwekhwalithi. I-catalyst idlala indima ebalulekile ekwenzeni ngcono izinga likaphethiloli lilonke ngokugqugquzela ukuguqulwa kwezinhlanganisela ezinesulfure zibe i-hydrogen sulfide.
Ngokufanayo, ku-hydrotreating ye-VGO ne-diesel, kokubiliI-HDS ne-HDNziyizinqubo ezibalulekile.I-GC-HP448 catalystyakhelwe ngokukhethekile ukuze ihlangabezane nezidingo ze-hydrotreating ze-VGO nezingxenyana zikadizili. Isusa ngempumelelo izinhlanganisela zesulfure ne-nitrogen, ngaleyo ndlela ithuthukise inombolo ye-cetane kanye nekhwalithi iyonke yamafutha edizili. Ukwengeza, i-catalyst isiza ekunciphiseni okuqukethwe kwesibabule ku-VGO, okubalulekile ukuhlangabezana nokucaciswa kwesibabule emikhiqizweni ehlukahlukene ephuma ku-VGO, efana nophethiloli wejethi nodizili.
Ama-Catalysts asetshenziselwa i-hydrotreating akhiwe ukuze abonise umsebenzi ophezulu, ukukhetha nokuzinza ngaphansi kwezimo zokusebenza ezinzima zenqubo yokucwenga. Ziklanyelwe ukumelana nokungcola nobuthi okungenzeka bukhona esitokisini sokuphakelayo, kuqinisekiswe impilo enwetshiwe ye-catalyst nokusebenza okungaguquki. Ukwengeza, inqubekelaphambili kubuchwepheshe be-catalyst iholele ekuthuthukisweni kwama-catalysts anokwenyuka kokumelana nokuvala ukusebenza, okusiza ukwandisa ukusebenza kahle nokusebenza kahle kwezindleko.
Ngokufigqiwe,i-hydrotreating catalystszibalulekile ekukhiqizeni okuphumelelayo nokuqhubekayo kwemikhiqizo ye-petroleum esezingeni eliphezulu. Ukuthuthuka kobuchwepheshe be-catalyst obumelwe i-GC-HP406 ne-GC-HP448 kukhuthaze kakhulu ukwenziwa kahle kwezinqubo ze-hydrotreating, ikakhulukazi ku-HDS ye-naphtha ne-VGO kanye ne-HDN kadizili. Njengoba isidingo samafutha ahlanzekile siqhubeka sikhula, indima ye-hydrotreating catalysts ekukhiqizeni izibaseli ezisebenza kahle ezihlangabezana nezidingo zemvelo ayikwazi ukubukelwa phansi. Ngokuqhubeka kwemizamo yocwaningo nentuthuko, kunesithembiso esikhulu esikhathini esizayo sokuqhubeka nokwenza ngcono ukusebenza kwama-hydrotreating catalysts, ngaleyo ndlela kuqhubekisele phambili imboni yokucwenga ekuzinzeni nasekusebenzeni kahle.
