Heavy Feed FCC Pretreatment Catalyst yog ib qho kev txhawb nqa hydrotreating catalyst engineered rau ruaj - txaj installation upstream ntawm cov kua catalytic cracking units. Nws ua cov khoom hnyav refinery feedstocks kom optimize hydrocarbon zoo ua ntej catalytic cracking.
Kev xaiv yog txiav txim siab los ntawm pub sulfur, nitrogen, hlau, Conradson Carbon Residue (CCR), boiling range, thiab chav ua haujlwm hnyav. Catalyst configurations tuaj yeem tsim kho rau hydrodesulfurization (HDS), hydrodenitrogenation (HDN), hydrodemetallization (HDM), lossis cov kab mob tshwj xeeb.
Lub hom phiaj feedstocks muaj xws li cov roj nqus tsev vacuum hnyav, sib sib zog nqus- txiav VGO, coker- tau txais cov roj roj, thiab siab - cov dej paug paug uas leej faj, nitrogen, npib tsib xee, vanadium, lossis asphaltene cuam tshuam rau kev ua haujlwm hauv qab.

Core Reaction Functions
Hydrodesulfurization (HDS)
Hloov cov sulfur-cov kabmob sib txuas rau hauv hydrocarbons thiab hydrogen sulfide siv cov pa roj hydrogen, txo cov sulfur load nqa mus rau theem tawg. Cov qib kev ua haujlwm yuav tsum tau nyob ntawm cov khoom noj sulfur, lub hom phiaj ntawm qhov hluav taws xob, lub zog ntawm lub tshuab hluav taws xob, qhov kub thiab txias, cov dej hauv ib teev (LHSV), thiab hydrogen ib nrab siab.
Hydrodenitrogenation (HDN)
Tshem tawm cov nitrogen tebchaw uas txwv tsis pub ua raws li cov tshuaj lom ib ntus lossis mus tas li kom tawg cov catalysts. Kev ua kom zoo HDN yog qhov tseem ceeb thaum ua cov nitrogen-nplua nuj VGO, cov roj coker hnyav, lossis cov khoom sib xyaw refractory.
Hydrodemetallization (HDM)
Lub hom phiaj ntawm kev tshem cov nickel thiab vanadium. Cov khoom noj hnyav hnyav yuav tsum tau ua tib zoo sib npaug ntawm qhov pore cov qauv thiab cov hlau siab - tuav lub peev xwm los tiv thaiv qhov ncauj qhov ncauj ntxov ntxov thiab catalyst deactivation. Cov txaj zov lossis ntau-catalyst grading systems feem ntau siv ua ntej ntawm cov txaj hydrotreating sib sib zog nqus.
Hydrogenation thiab Aromatic Saturation
Saturates aromatic rings thiab ntau-ntiv nplhaib qauv, txhim kho hydrogen- mus rau -carbon ratios, txhim kho pub ceev, thiab optimizing downstream cov khoom faib.
Catalyst Cycle Life thiab Regeneration
Deactivation Control
Engineered pore structures txo qhov pore qhov ncauj ntsaws los ntawm hnyav asphaltene thiab npib tsib xee / vanadium deposition.
Kev ua haujlwm ruaj khov
Formulated rau lub voj voog ntev ntev nyob rau hauv siab -cov kev ua kom zoo zoo.
Regeneration Compatibility
Txhawb nqa cov txheej txheem kev lag luam rov tsim dua tshiab uas muaj feem xyuam, nyob ntawm qhov tsim qauv thiab qib hlau tsub zuj zuj.
Manufacturing thiab Quality Assurance
Catalyst ntau lawm siv automated Distributed Control Systems (DCS) los saib xyuas precursor impregnation, ziab, calcination, thiab extrusion theem.

FAQ
Q: Yuav ua li cas pub silicon lossis hlau paug cuam tshuam rau kev xaiv catalyst, thiab nws tswj tau li cas?
A: Coker- tau txais cov kwj los yog cov roj coker qeeb qeeb feem ntau muaj cov kab mob silicon los ntawm cov tshuaj tua kab mob thiab cov khoom siv hlau. Silicon mus tas li tshuaj lom cov chaw ua haujlwm catalytic, thaum hlau tso rau ntawm lub qhov ncauj qhov ncauj thiab ua kom lub siab poob. When processing silicon- or iron-laden feeds, the catalyst system requires modified guard layers with specialized macroporous structures to trap contaminants before they reach the main HDS/HDN active zones.
Q: Cov catalyst no puas tuaj yeem thauj khoom raws li kev hloov pauv ncaj qha hauv cov chaw lag luam hydrotreating uas twb muaj lawm yam tsis muaj kev hloov pauv reactor?
A: Yog. Catalyst particle qhov ntev, xws li tus qauv thooj voos kheej kheej, trilobes, los yog customized geometries, thiab bulk ntom yog engineered kom phim tus qauv ruaj - txaj loading xyaum. Qhov no ua kom ntseeg tau tias qhov poob siab, qhov tsis muaj feem, thiab cov kua dej faib ua ke nrog cov reactor internals uas twb muaj lawm, quench zones, thiab grading baskets.
Q: Dab tsi yog txheej txheem txheej txheem rau sulfurization thiab ua kom muaj zog ua ntej kev qhia zaub mov?
A: Hydrotreating catalysts feem ntau xav tau hauv -situ lossis ex-situ presulfurization los hloov cov hlau oxides rau hauv cov hlau sulfide theem. Cov txheej txheem pib txheej txheem suav nrog kev ziab, ntub dej -spiking lossis roj-theem sulfiding siv dimethyl disulfide lossis sib npaug sulfiding cov neeg ua haujlwm nyob rau hauv kev tswj qhov kub thiab txias ramps thiab hydrogen ncig kom ua tiav qhov pib catalytic siab tshaj plaws.
Q: Yuav ua li cas batch - rau - batch lub cev thiab tshuaj variations tswj thaum lub sij hawm tsim khoom?
A: Kev tsim khoom siv DCS- soj ntsuam impregnation, automated calcination, thiab cov txheej txheem tswj xyuas nruj. Every manufacturing lot undergoes independent testing for surface area, pore volume, active metal dispersion, bulk density, and single-pellet crushing strength, with lot-specific certificates of analysis provided prior to dispatch.
