Hydrotreating catalystskuita basa rakakosha mukunatswa kwezvinhu zvepetroleum, kunyanya muhydrodesulfurization (HDS) ye naphtha, vacuum gasi mafuta (VGO) uye dhiziri ine sulfur yakaderera (ULSD) Aya ma catalyst akakosha pakubvisa sarufa, nitrogen uye kumwe kusvibiswa kubva kune crude oil fractions, nekudaro kuvandudza kunaka uye kutevedza kwezvakatipoteredza kwechigadzirwa chekupedzisira. Kuti tinzwisise kukosha kwehydrotreating catalysts, zvinodikanwa kunyura mune iyo pfungwa ye hydrotreating uye basa rezvinokonzeresa mukuita.
Chii chinonzi hydrotreating catalyst?
Hydrotreating catalysts zvinhu zvinokurudzira kuita kwemakemikari kunowanikwa muhydrotreating yezvikamu zvemafuta asina kukora. Hydrotreating inoreva seti yemaitiro anokonzeresa anosanganisira kushandiswa kwehydrogen kubvisa tsvina uye kunatsiridza mhando yezvakasiyana zvigadzirwa zvepetroleum. Mhando huru dzehydroprocessing inosanganisira hydrotreating, hydrocracking,uyehydrofinishing, imwe neimwe inoda ma catalysts anoenderana nezvaunoda kuita.
Naphtha Hydrotreating Catalyst
Naphtha hydrotreating inosanganisira kubvisa sarufa, nitrogen uye kumwe kusvibiswa kuti isangane nemirairo yakasimba yezvakatipoteredza uye kuvandudza kunaka kweoctane yechigadzirwa. Catalysts anoshandiswa mukatinaphtha hydrotreatinganowanzo kuve akavakirwa pasimbi senge cobalt, molybdenum uye nickel inotsigirwa paaluminium kana zvimwe zvinhu zvakakwirira pamusoro penzvimbo. Aya macatalyst anokurudzira hydrogenation uye desulfurization reactions kugadzira yakaderera-sarufa, yakakwirira-octane naphtha yakakodzera kusanganiswa kuita peturu.
VGO HDS
Vacuum gasi mafuta(VGO) yakakosha feedstock kune dzakasiyana siyana dzepasi, kusanganisira fluidized bed catalytic cracking (FCC) uye hydrocracking. Nekudaro, VGO kazhinji ine yakakwira sarufa uye nitrogen, iyo inoda kuderedzwa kuti isangane nechigadzirwa. Hydrotreating catalysts yakagadzirirwa chaizvoVGO HDSdzakanyatsogadzirwa kuti dzimirire mamiriro ekushanda akaoma uye kukurudzira kubviswa kwesarufa uye nitrogen mishonga, zvichiita kuti ichenese, yakakosha VGO kuti iwedzere kugadziriswa.
Nekuda kwekuomesera emission standards, Ultra-low sulfur diesel (ULSD) chigadzirwa chakakosha muindasitiri yemazuva ano yekunatsa. Kugadzirwa kweULSD kunosanganisira hydrotreating kudzikisa zvemukati sarufa kusvika kune yakaderera-yakaderera. ULSD HDS catalysts inosarudza zvakanyanya desulfurization uku ichideredza hydrogenation yezvimwe zvikamu, kuve nechokwadi chinodiwa chigadzirwa chemhando uye kusangana nezvinodiwa.
Basa re catalyst
Mune ese aya maitiro e hydrotreating, catalysts anoita basa rakakosha mukusimudzira maitiro anodiwa uchichengetedza kugadzikana kwenguva refu uye chiitiko. Sarudzo yekugadzira catalyst, kusanganisira mhando uye kusungirirwa kwesimbi inoshanda uye zvinhu zvinotsigira, zvinokanganisa zvakanyanya kushanda uye kusarudzwa kweiyo hydrotreating reaction. Pamusoro pezvo, kufambira mberi mune tekinoroji yecatalyst, senge kuvandudzwa kwesimbi-yakasimudzirwa maumbirwo uye yakagadziridzwa zvinhu zvekutsigira, ramba uchivandudza mashandiro uye hupenyu hurefu hwehydroprocessing catalysts.
mukupedzisa
Hydrotreating catalystszvakakosha pakugadzira zvinhu zvakachena, zvemhando yepamusoro petroleum. Sezvo mirau yezvakatipoteredza ichiwedzera kuomarara, kudiwa kweanoshanda uye anosarudza zvinokonzeresa mune hydrotreating maitiro anoramba achikura. Kuenderera mberi kwekutsvagisa uye basa rekusimudzira mune catalyst tekinoroji ine chinangwa chekuwedzera kuvandudza mashandiro uye kusimba kwehydroprocessing catalysts, kuve nechokwadi chekugadzirwa kweramangwana kwemafuta ane hushamwari uye petrochemicals.
