I-Hydrotreating catalystsidlala indima ebalulekileyo ekusulungekisweni kweemveliso zepetroleum, ngakumbi kwi-hydrodesulfurization (HDS) ye-naphtha, i-oyile yerhasi yofukula (VGO) kunye ne-ultra-low sulphur diesel (ULSD). Ezi zixhobo zibalulekile ekususeni isulfure, initrogen kunye nobunye ukungcola kumaqhezu e-oyile ekrwada, ngaloo ndlela kuphuculwe umgangatho kunye nokuthotyelwa kokusingqongileyo kwemveliso yokugqibela. Ukuqonda ukubaluleka kwei-hydrotreating catalysts, kuyimfuneko ukukhangela kwingcamango ye-hydrotreating kunye nendima ye-catalysts kwinkqubo.
Yintoni i-hydrotreating catalyst?
I-Hydrotreating catalysts zizinto ezikhuthaza ukusabela kweekhemikhali ezibandakanyekayo kwi-hydrotreating yamaqhezu e-oyile ekrwada. I-Hydrotreating ibhekiselele kwiseti yeenkqubo ze-catalytic ezibandakanya ukusetyenziswa kwe-hydrogen ukususa ukungcola kunye nokuphucula umgangatho weemveliso ezahlukeneyo zepetroleum. Iintlobo eziphambili zei-hydroprocessing ibandakanya i-hydrotreating, i-hydrocracking, kwayei-hydrofinishing, nganye ifuna i-catalysts ethile eyenzelwe ukusabela okufunayo.
INaphtha Hydrotreating Catalyst
I-Naphtha hydrotreating ibandakanya ukususa isulfure, initrogen kunye nobunye ukungcola ukuhlangabezana nemigaqo engqongqo yokusingqongileyo kunye nokuphucula umgangatho we-octane yemveliso. IiCatalysts ezisetyenziswa kwinaphtha hydrotreatingngokwesiqhelo zisekwe kwiintsimbi ezifana necobalt, imolybdenum kunye nenickel exhaswa kwialumina okanye ezinye izinto ezikumgangatho ophezulu. Ezi catalysts zikhuthaza i-hydrogenation kunye ne-desulfurization reactions ukuvelisa i-low-sulfur, i-octane ephezulu ye-octane naphtha efanelekileyo ukuxuba kwi-petroli.
VGO HDS
Vacuum ioli yerhasi(VGO) sisixhobo sokutya esibalulekileyo kwiinkqubo ezahlukeneyo zomlambo, kubandakanywa i-fluidized bed catalytic cracking (FCC) kunye ne-hydrocracking. Nangona kunjalo, i-VGO ihlala iqulethe amanqanaba aphezulu esulfure kunye ne-nitrogen, efuna ukuncitshiswa ukuhlangabezana neenkcukacha zemveliso. I-Hydrotreating catalysts eyilelwe ngokukodwaVGO HDSziqulunqwe ngononophelo ukuze zimelane neemeko zokusebenza ezinzima kwaye zikhuthaze ukususwa kweekhompawundi zesulfure kunye ne-nitrogen, okubangela ukuba i-VGO icoceke, ixabiseke ngakumbi ukuze kuqhutywe phambili.
Ngenxa yemigangatho engqongqo yokukhutshwa, idizili yesulphur ephantsi kakhulu (ULSD) yimveliso ephambili kushishino lwangoku lokusulungekisa. Ukuveliswa kwe-ULSD kubandakanya i-hydrotreating ukunciphisa umxholo wesulfure kumanqanaba aphantsi kakhulu. I-ULSD HDS catalysts ikhetha kakhulu i-desulfurization ngelixa inciphisa i-hydrogenation yamanye amacandelo, iqinisekisa umgangatho wemveliso ofunekayo kunye nokuhlangabezana neemfuno zokulawula.
Indima ye-catalyst
Kuzo zonke ezi nkqubo ze-hydrotreating, ii-catalysts zidlala indima ephambili ekukhuthazeni iimpendulo ezifunwayo ngelixa zigcina uzinzo kunye nomsebenzi wexesha elide. Ukukhethwa kokuqulunqwa kwe-catalyst, kubandakanywa uhlobo kunye nokugxininiswa kweentsimbi ezisebenzayo kunye nezixhobo zokuxhasa, kuchaphazela kakhulu ukusebenza kunye nokukhetha kwe-hydrotreating reaction. Ukongezelela, ukuqhubela phambili kwi-teknoloji ye-catalyst, njengokuphuhliswa kweendlela ezintsha zetsimbi ezikhuthazwayo kunye nezixhobo zokuxhasa eziphuculweyo, ziqhubeka nokuphucula ukusebenza kunye nokuphila ixesha elide kwe-hydroprocessing catalysts.
ukuququmbela
I-Hydrotreating catalystszibalulekile ekuveliseni iimveliso zepetroleum ezicocekileyo nezikumgangatho ophezulu. Njengoko imimiselo yokusingqongileyo iba nzima ngakumbi, imfuno ye-catalysts esebenzayo kunye ekhethiweyo kwiinkqubo ze-hydrotreating iyaqhubeka ikhula. Uphando oluqhubekayo kunye nomsebenzi wophuhliso kwi-teknoloji ye-catalyst ijolise ekuphuculeni ngakumbi ukusebenza kunye nokuzinza kwe-hydroprocessing catalysts, ukuqinisekisa ukuveliswa kwexesha elizayo lamafutha angenabungozi kokusingqongileyo kunye ne-petrochemicals.
