Hydrotreating inzira yakakosha mukunatsa chigadzirwa chepetroleum, nechinangwa chekubvisa tsvina nekuvandudza kunaka kwemafuta. Macatalysts anoshandiswa muhydrotreating anoita basa rakakosha mukufambisa izvi. Chimwe chezvinangwa zvikuru zve hydrotreating ndechekubvisa sarufa, nitrogen uye kumwe kusvibiswa kubva kune akasiyana crude oil fractions, senge naphtha, vacuum gas oil (VGO) uye dhiziri. Ichi chinyorwa chichapa kutarisa kwakadzama kwekukosha kwehydrotreating catalysts, kunyanya mu hydrodesulfurization (HDS) ye naphtha neVGO uye hydrodenitrification (HDN) yemafuta edhiziri.
Hydrotreating catalysts yakakosha kune hydrofinishing process nekuda kwekugona kwavo kushandura zvisingadiwe sarufa uye nitrogen makomisheni kuita iwo akasiyana hydrogen sulfide uye ammonia mafomu. Kutendeuka uku kunowanikwa kuburikidza nenhevedzano yecatalytic reactions inoitika pasi pekushisa kwepamusoro uye high pressure condition. Zviviri zvinozivikanwa zvinokonzeresa zvinoshandiswa mu hydrotreating ndizvoGC-HP406uyeGC-HP448, iyo yakanyatsogadzirirwa zvikamu zvakasiyana zvemafuta asina kuchena.
Panyaya ye naphtha, hydrodesulfurization inhanho yakakosha muhydrotreating sezvo naphtha iriyo huru yekudyisa kugadzirwa kwepeturu. TheGC-HP406catalystyakanyatsogadzirirwa kusimudzira kubviswa kwe sulfur compounds kubva ku naphtha, kuve nechokwadi kuti chigadzirwa chekupedzisira chinoenderana nemitemo yakasimba yezvakatipoteredza uye maitiro ehutano. Iyo catalyst inoita basa rakakosha mukuvandudza huwandu hwese hwepeturu nekusimudzira kushandurwa kwemakomisheni ane sarufa kuita hydrogen sulfide.
Saizvozvo, mune hydrotreating yeVGO uye dhiziri, ese ari maviriHDS uye HDNmaitiro akakosha.GC-HP448 catalystyakanyatsogadzirwa kuti isangane nezvinoda hydrotreating zveVGO uye zvikamu zvedhiziri. Iyo inonyatsobvisa sulfur uye nitrogen makomisheni, nekudaro inovandudza nhamba yecetane uye huwandu hwese hwemafuta edhiziri. Pamusoro pezvo, iyo catalyst inobatsira kudzikisa sulfuri zvirimo muVGO, iyo yakakosha kusangana nesarufa zvakatemwa zvezvakasiyana-siyana zvakabva kuVGO zvigadzirwa, senge mafuta ejeti nedhiziri.
Catalysts anoshandiswa mu hydrotreating anogadzirwa kuti aratidze basa repamusoro, kusarudza uye kugadzikana pasi pemamiriro ekushanda akaomarara ekunatsa maitiro. Izvo zvakagadzirirwa kutsungirira zvinosvibisa uye chepfu inogona kunge iripo mune feedstock, kuve nechokwadi chekuwedzera hupenyu hwekuita uye kuita kunoenderana. Pamusoro pezvo, kufambira mberi kwehunyanzvi hwekugadzira tekinoroji kwakonzera kuvandudzwa kwezvinokonzeresa nekuwedzera kuramba kudzima, zvichibatsira kuwedzera kushanda zvakanaka uye mutengo-kubudirira.
Muchidimbu,hydrotreating catalystsakakosha pakugadzirwa kwakanaka uye kwakasimba kwezvigadzirwa zvepetroleum zvemhando yepamusoro. Kufambira mberi kwehunyanzvi hwekugadzira tekinoroji inomiririrwa neGC-HP406 uye GC-HP448 yakasimudzira zvakanyanya optimization yemahydrotreating process, kunyanya muHDS yenaphtha neVGO uye HDN yedhiziri. Sezvo kudiwa kwemafuta akachena kuri kuramba kuchikura, basa rema hydrotreating catalysts mukugadzira mafuta emhando yepamusoro anosangana nezvinodiwa kwezvakatipoteredza haagone kurerutswa. Kuburikidza nekuenderera mberi kwekutsvaga nekuedza kwekusimudzira, kune chivimbiso chikuru mune ramangwana chekuwedzera kuvandudza kushanda kwehydrotreating catalysts, nekudaro kufambisa indasitiri yekunatsa kune kusimudzira nekubudirira kukuru.
