I-Hydrotreating yinkqubo ephambili yokusulungekiswa kwemveliso ye-petroleum, ejolise ekususeni ukungcola kunye nokuphucula umgangatho wamafutha. Ii-catalysts ezisetyenziselwa i-hydrotreating zidlala indima ebalulekileyo ekuququzeleleni le nkqubo. Enye yeenjongo eziphambili ze-hydrotreating kukususa isulfure, i-nitrogen kunye nezinye izinto ezingcolileyo ezivela kwiindawo ezahlukeneyo zeoli ekrwada, njenge-naphtha, i-vacuum gas oil (VGO) kunye ne-diesel. Eli nqaku liza kunika ujongo olunzulu ngokubalulekai-hydrotreating catalysts, ngokukodwa kwi-hydrodesulfurization (HDS) ye-naphtha kunye ne-VGO kunye ne-hydrodenitrification (HDN) ye-diesel fuel.
I-Hydrotreating catalysts ibaluleke kakhulu kwinkqubo yokugqitywa kwe-hydrofining ngenxa yokukwazi ukuguqula iikhompawundi zesulfure ezingafunwayo kunye ne-nitrogen zibe yi-hydrogen sulfide kunye neefom ze-ammonia. Olu guqulelo luphunyezwa ngoluhlu lweempendulo ze-catalytic ezenzeka phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. Ii-catalysts ezimbini ezaziwayo ezisetyenziswa kwi-hydrotreating ziGC-HP406kwayeGC-HP448, eyenzelwe ngokukodwa amaqhezu eoli ekrwada ahlukeneyo.
Kwimeko ye-naphtha, i-hydrodesulfurization linyathelo eliphambili kwi-hydrotreating kuba i-naphtha yeyona nto yokutya yokuvelisa i-petroli. IGC-HP406i-catalystyenzelwe ngokukodwa ukukhuthaza ngokufanelekileyo ukukhutshwa kwe-sulfur compounds kwi-naphtha, ukuqinisekisa ukuba imveliso yokugqibela ihambelana nemimiselo engqongqo yokusingqongileyo kunye neenkcukacha zomgangatho. I-catalyst idlala indima ebalulekileyo ekuphuculeni umgangatho wepetroli ngokubanzi ngokukhuthaza ukuguqulwa kweekhompawundi ezinesulfure zibe yi-hydrogen sulfide.
Ngokufanayo, kwi-hydrotreating ye-VGO kunye ne-diesel, zombiniHDS kunye HDNziinkqubo ezibalulekileyo.GC-HP448 catalystyenziwe ngokukodwa ukuhlangabezana neemfuno ze-hydrotreating ze-VGO kunye namaqhezu edizili. Isusa ngokufanelekileyo i-sulfure kunye ne-nitrogen compounds, ngaloo ndlela iphucula inani le-cetane kunye nomgangatho jikelele we-diesel fuel. Ukongeza, i-catalyst inceda ukunciphisa umxholo wesulfure kwi-VGO, ebaluleke kakhulu ukuhlangabezana neenkcukacha zesulfure kwiimveliso ezahlukeneyo eziphuma kwi-VGO, ezifana ne-jet fuel kunye ne-diesel.
I-Catalysts ezisetyenziselwa i-hydrotreating zenziwe ukuba zibonise umsebenzi ophezulu, ukukhetha kunye nokuzinza phantsi kweemeko zokusebenza ezinzima zenkqubo yokucoca. Zenzelwe ukumelana nongcoliseko kunye neetyhefu ezinokuthi zibekho kwi-feedstock, ziqinisekisa ubomi obude be-catalyst kunye nokusebenza okungaguqukiyo. Ukongezelela, ukuqhubela phambili kwitekhnoloji ye-catalyst kuye kwakhokelela ekuphuhlisweni kwee-catalysts kunye nokunyuka kokuchasana nokucima, kunceda ukwandisa ukusebenza kakuhle kunye nokusebenza kakuhle kweendleko.
Isishwankathelo,i-hydrotreating catalystsziyimfuneko kwimveliso esebenzayo nezinzileyo yeemveliso zepetroleum ezikumgangatho ophezulu. Ukuqhubela phambili kweteknoloji ye-catalyst emelwe yi-GC-HP406 kunye ne-GC-HP448 ikhuthaze kakhulu ukuphuculwa kweenkqubo ze-hydrotreating, ngakumbi kwi-HDS ye-naphtha kunye ne-VGO kunye ne-HDN ye-diesel. Njengoko imfuno yamafutha acocekileyo iqhubeka ikhula, indima ye-hydrotreating catalysts ekuveliseni i-fuel-performance fuels ehlangabezana neemfuno zokusingqongileyo ayinakujongelwa phantsi. Ngokuqhuba uphando oluqhubekayo kunye neenzame zophuhliso, kukho isithembiso esikhulu kwixesha elizayo ukuqhubela phambili ukuphucula ukusebenza kwe-hydrotreating catalysts, ngaloo ndlela uqhubela ishishini lokusulungekisa ukuzinza kunye nokusebenza kakuhle.
