I-Hydrotreating inqubo ebalulekile ekucoculweni komkhiqizo kaphethiloli, okuhlose ukususa ukungcola nokwenza ngcono ikhwalithi kagesi. Ama-catalysts asetshenziswa e-hydrotreating adlala indima ebalulekile ekwenzeni lula le nqubo. Enye yezinhloso eziphambili ze-hydrotreating ukususa isibabule, i-nitrogen kanye nokunye ukungcola okuvela kwezingxenyana ezihlukene ze-crude, ezinjengeNaphtha, uwoyela we-vacuum gesi (vgo) nodizili. Le ndatshana izonikeza ukubukeka okujulile ngokubaluleka kokubaluleka kweAma-Hydrotreating Catalysts, ngqo eHydrodesulfurhanization (HDS) yeNaphtha ne-VGO neHydrodenitrization (HDN) kaphethiloli kadizili.
I-Hydrotreating Catalysts ibaluleke kakhulu kwinqubo ye-hydrofinishing ngenxa yekhono labo lokuguqula isibabule elingafuneki kanye nama-nitrogen amakhompiyutha abe yi-hydrogen sulfide kanye nama-ammonia amafomu. Lokhu kuguqulwa kutholakala ngochungechunge lokusabela kwe-catalytic okwenzeka ngaphansi kokushisa okuphezulu kanye nezimo eziphakeme zokucindezela. Ama-catalysts amabili owaziwayo asetshenziswa ku-hydrotreating kukhonaGC-HP406na-GC-HP448, eklanyelwe ngqo izingxenyana ezihlukile zamafutha.
Endabeni kaNaphtha, i-HydrodesulfurIzation isinyathelo esiyisihluthulelo esiseHydrotreating selokhu uNaphtha yiyona ephambili feedstock yokukhiqiza uphethiloli. Le khasiGC-HP406inhlehlingststIklanyelwe ukuthuthukisa ngempumelelo ukususwa kwamakhompiyutha sulfur kusuka kwaNaphtha, ukuqinisekisa ukuthi umkhiqizo wokugcina uhambisana nemithetho eqinile yemvelo kanye nemininingwane yekhwalithi. I-Catalyst idlala indima ebalulekile ekuthuthukiseni ikhwalithi ephelele kaphethili ngokuqhakambisa ukuguqulwa kwamakhompiyutha aqukethe ama-sulfur ku-hydrogen sulfide.
Ngokufanayo, e-hydrotreating of vgo nodizili, bobabiliI-HDS ne-HDNizinqubo ezibalulekile.GC-HP448 Catalystihlelwe ngokukhethekile ukufeza izidingo ze-hydrotreating of vgo and diesel izingxenyana. Isusa ngempumelelo ama-sulphur nama-nitrogen compounds, ngaleyo ndlela ethuthukisa inombolo ye-cetane nekhwalithi ephelele yamafutha edizili. Ngokwengeziwe, i-Catalyst isiza ukunciphisa okuqukethwe se-sulfur eVgo, okubaluleke kakhulu ukubhekana nokucaciswa kwesibabule kwemikhiqizo ehlukahlukene ye-vgo-okususelwa ku-vgo-okususelwa, njengodizili.
Ama-Catalysts asetshenziswa e-hydrotreating anenjinizo ekhombisa umsebenzi ophakeme, khetha u-Seleaty kanye nokuqina ngaphansi kwezimo ezinzima zokusebenza kwenqubo yokuhlanzeka. Zenzelwe ukubekezelela ukungcola kanye nobubi obungaba khona endaweni yokuphakelayo, kuqinisekiswe impilo ye-catalyst enwetshiwe kanye nokusebenza okungaguquki. Ngokwengeziwe, intuthuko ebukhwini be-catalyst iholele ekuthuthukisweni kwama-catalysts ngokumelana okwandayo ekusebenzeni, ekusizeni ukukhulisa ukusebenza kahle kanye nokusebenza kwezindleko.
Ngokufigqiwe,Ama-Hydrotreating Catalystszibaluleke kakhulu ekukhiqizweni okusebenzayo nokuzinzile kwemikhiqizo esezingeni eliphakeme kaphethiloli. Ukuthuthukiswa kwe-Catalyst Technology okumelwe yi-GC-HP406 ne-GC-HP448 kukhuthaze kakhulu ukusebenza kwezinqubo ze-hydrotreating, ikakhulukazi ku-HDS kaNaphtha neVgo ne-HDN of Diesel. Njengoba ukufunwa kwamafutha okuhlanza kuqhubeka nokukhula, indima ye-hydrotreating carlysts ekukhiqizeni ama-fuels asebenza kahle ahlangabezana nezidingo zemvelo azikwazi ukubulawa. Ngokucwaninga okuqhubekayo kanye nemizamo yentuthuko, kunesithembiso esihle ngokuzayo ukuze uthuthukise ukusebenza kahle kwama-cardrotreating carlysts, ngaleyo ndlela uqhubekele imboni yokucwengisisa ekusebenzeni nasekusebenzeni kahle.
