Ama-Hydrotreating Catalystsdlala indima ebalulekile ekutholweni kwemikhiqizo kaphethiloli, ikakhulukazi e-hydrodesulization (Ama-HD) kaNaphtha, uwoyela wegesi we-Vacuum (Uhlobo lwegazi lokutholwa phansi) kanye ne-ultra-low sulfur diesel (Ulsd). Lawa ma-catalysts abucayi ekususeni isibabule, i-nitrogen kanye nokunye ukungcola okuvela kwizingxenyana zamafutha e-crude, ngaleyo ndlela kuthuthukise ikhwalithi kanye nokuhambisana nomkhiqizo wokugcina. Ukuqonda ukubaluleka kweAma-Hydrotreating Catalysts, kuyadingeka ukudonsa emcabangweni we-hydrotreating kanye neqhaza lama-catalysts kule nqubo.
Yini i-hydrotreting catalyst?
I-Hydrotreating Catalysts yizinto ezikhuthaza ukusabela kwamakhemikhali ababambe iqhaza ku-hydrotreating of crude kawoyela izingxenyana. I-Hydrotreating isho isethi yezinqubo ze-catalytic ezibandakanya ukusetshenziswa kwe-hydrogen ukususa ukungcola nokuthuthukisa ikhwalithi yemikhiqizo ehlukahlukene kaphethiloli. Izinhlobo eziphambili zeIHydroprocessing ifaka i-hydrotreating, i-hydrocracking, futhihydrofinishing, ngamunye adinga ama-catalysts athile ahambisana nokusabela okufiselekayo.
UNaphtha Hydrotreating Catalyst
UNaphtha Hydrotreating ubandakanya ukususa isibabule, i-nitrogen nokunye ukungcola ukuze ahlangabezane nemithetho eqinile yezemvelo futhi athuthukise ikhwalithi yomkhiqizo. Ama-catalysts asetshenziswe ngaphakathinaphtha hydrotreatingNgokuvamile kususelwa kwizinsimbi ezinjenge-cobalt, i-molybdenum ne-nickel zisekelwa ku-alumina noma ezinye izinto eziphakeme zendawo. Lawa ma-catalysts akhuthaza i-hydrogenation kanye nokusabela kokususela ukukhiqiza i-sulfur ephansi, i-High-Octane Naphtha efanelekile ngokuhlanganiswa kophethiloli.
Vgo hds
I-Vacuum gesi Amafutha(Vo) iyisididi sokudla esibalulekile ngezinqubo ezahlukahlukene ezansiwa phansi, kufaka phakathi ukuqhekeka kombhede kashukela Kodwa-ke, i-VGO ivame ukuqukethe amazinga aphezulu esibabule ne-nitrogen, edinga ukwehliswa ukuze kuhlangatshezwane nokucaciswa komkhiqizo. Ama-Hydrotreating Catalysts aklanyelwe ngqoVgo hdszimiswe ngokucophelela ukumelana nezimo ezinzima zokusebenza futhi zikhuthaze ukususwa kwama-sulfur nama-nitrogen compound, okuholela ekuhlanzeni, okubangelwa ukwenziwa kwe-vgo ebaluleke kakhulu.
Ngenxa yamazinga okuphuma aqinile, u-Ultra-Low Sulfur Diesel (Ulsd) ngumkhiqizo obalulekile embonini yanamuhla yokucwengeka. Ukukhiqizwa kwe-Ulsd kufaka phakathi i-hydrotreating ukunciphisa okuqukethwe sulfur kumazinga aphansi we-Ultra-aphansi. Ama-ulsd hds ama-catalysts akhetha kakhulu ukusungula ngenkathi unciphisa ama-hydrogenation kwezinye izingxenye, uqinisekise ikhwalithi yomkhiqizo edingekayo kanye nezidingo zokulawula.
Indima ye-catalyst
Kuzo zonke lezi zinqubo zokuzijabulisa kwe-hydrotreating, ama-cardysts adlala indima enkulu ekuthuthukiseni ukusabela okufisayo ngenkathi egcina ukuqina kanye nokuqina kwesikhathi eside. Ukukhethwa kwekwakheka kwe-catalyst, kufaka phakathi uhlobo kanye nokuqoqwa kwezinsimbi ezisebenzayo nezinto zokweseka, kuthinta kakhulu ukusebenza kahle kanye nokukhetha ukusabela kwe-hydrotreating. Ngokwengeziwe, ukuthuthuka kobuchwepheshe be-catalyst, njengokuthuthukiswa kwezindlela ezintsha zensimbi ezikhuthaze ngensimbi kanye nezinto zokweseka ezithuthukisiwe, qhubeka nokwenza ngcono ukusebenza nokuphila isikhathi eside kwama-hydroprocessing Catalysts.
Ekuphetheni
Ama-Hydrotreating Catalystszibalulekile ekukhiqizeni imikhiqizo ehlanzekile, ephakeme yekhwalithi ye-petroleum. Njengoba imithetho yezemvelo iba nzima ngokwengeziwe, isidingo sama-catalysts asebenzayo futhi akhetha izinqubo ze-hydrotreating ayaqhubeka nokukhula. Umsebenzi oqhubekayo wokucwaninga nobuchwepheshe beCatalyst ubuchwepheshe obuhlose ukuthuthukisa ukusebenza nokuqina kwama-cardroprocessing carlysts, uqinisekisa ukukhiqizwa kwesikhathi esizayo kwamafutha omvelo kanye nama-petrochemicals.
