Hydrotreating catalystsimagwira ntchito yofunika kwambiri pakuyenga zinthu zamafuta, makamaka mu hydrodesulfurization (Zithunzi za HDSmafuta a naphtha, vacuum gasi (VGO) ndi dizilo ya sulfure yotsika kwambiri (ULSD). Zothandizira izi ndizofunikira kwambiri pakuchotsa sulfure, nayitrogeni ndi zonyansa zina m'tigawo ta mafuta osakhazikika, potero kumapangitsa kuti mafutawo azigwirizana ndi chilengedwe. Kuti timvetse kufunika kwahydrotreating catalysts, m'pofunika kufufuzidwa mu lingaliro la hydrotreating ndi udindo wa catalysts mu ndondomekoyi.
Kodi hydrotreating catalyst ndi chiyani?
Hydrotreating chothandiziras ndi zinthu zomwe zimalimbikitsa kuyamwa kwa mankhwala omwe amaphatikizidwa mu hydrotreating ya tizigawo ta mafuta amafuta. Hydrotreating imatanthawuza njira zothandizira zomwe zimakhudza kugwiritsa ntchito haidrojeni kuchotsa zonyansa ndikuwongolera zinthu zosiyanasiyana zamafuta. Mitundu yayikulu yahydroprocessing ikuphatikizapo hydrotreating, hydrocracking,ndihydrofinishing, chilichonse chimafuna chothandizira kuti chigwirizane ndi zomwe mukufuna.
Naphtha Hydrotreating Catalyst
Naphtha hydrotreating imaphatikizapo kuchotsa sulfure, nayitrogeni ndi zonyansa zina kuti zikwaniritse malamulo okhwima a chilengedwe ndikusintha mtundu wa octane wazinthuzo. Ma catalysts omwe amagwiritsidwa ntchitonaphtha hydrotreatingnthawi zambiri zimatengera zitsulo monga cobalt, molybdenum ndi faifi tambala zomwe zimathandizidwa ndi alumina kapena zida zina zapamwamba. Zothandizira izi zimalimbikitsa hydrogenation ndi desulfurization reactions kuti apange otsika sulfure, high-octane naphtha yoyenera kusakaniza kukhala mafuta.
VGO HDS
Phunzirani mafuta a gasi(VGO) ndi chakudya chofunikira kwambiri panjira zosiyanasiyana zakutsika, kuphatikiza ma fluidized bed catalytic cracking (FCC) ndi hydrocracking. Komabe, VGO nthawi zambiri imakhala ndi sulfure ndi nayitrogeni wambiri, zomwe zimafunika kuchepetsedwa kuti zigwirizane ndi zomwe zagulitsidwa. Ma hydrotreating catalysts opangidwira makamakaVGO HDSamapangidwa mosamala kuti athe kupirira zovuta zogwirira ntchito ndikulimbikitsa kuchotsedwa kwa mankhwala a sulfure ndi nayitrogeni, zomwe zimapangitsa VGO yoyera, yamtengo wapatali kuti ipitirire kukonzanso.
Chifukwa cha malamulo okhwima, dizilo ya sulfure yotsika kwambiri (ULSD) ndi chinthu chofunikira kwambiri pamakampani oyenga amakono. Kupanga kwa ULSD kumaphatikizapo hydrotreating kuti muchepetse sulfure kukhala yotsika kwambiri. Zothandizira za ULSD HDS zimasankha kwambiri desulfurization pomwe zimachepetsa hydrogenation yazinthu zina, kuwonetsetsa kuti zinthu zili bwino komanso kukwaniritsa zofunikira.
Udindo wa chothandizira
Munjira zonsezi za hydrotreating, zothandizira zimagwira ntchito yofunika kwambiri polimbikitsa zomwe mukufuna ndikusunga bata ndi ntchito yayitali. Kusankhidwa kwa chothandizira kupanga, kuphatikizapo mtundu ndi kuchuluka kwa zitsulo zogwira ntchito ndi zipangizo zothandizira, zimakhudza kwambiri mphamvu ndi kusankha kwa hydrotreating reaction. Kuonjezera apo, kupita patsogolo kwa teknoloji yothandizira, monga kupanga mapangidwe atsopano opangidwa ndi zitsulo ndi zipangizo zowonjezera zothandizira, zikupitiriza kupititsa patsogolo ntchito ndi moyo wautali wa hydroprocessing catalysts.
Pomaliza
Hydrotreating catalystsndizofunika kwambiri popanga mafuta oyeretsera, apamwamba kwambiri. Pamene malamulo a chilengedwe akukhala okhwima, kufunikira kwa zopangira zogwira mtima komanso zosankhidwa mu njira za hydrotreating zikukulirakulira. Ntchito yopitilira kafukufuku ndi chitukuko muukadaulo waukadaulo ikufuna kupititsa patsogolo magwiridwe antchito komanso kukhazikika kwa zopangira ma hydroprocessing, kuwonetsetsa kuti mtsogolomo padzakhala mafuta otetezedwa ndi chilengedwe komanso mafuta a petrochemicals.
