I. Vim li cas Hydrogenation Catalysts Inseparable los ntawm Pseudo Boehmite?
Hydrogenation catalysts feem ntau muaj ob ntu: cov khoom siv ua haujlwm (xws li Co, Mo, Ni, W hlau sulfides lossis cov hlau muaj txiaj ntsig) thiab kev txhawb nqa.Pseudo boehmite(uas hloov mus rau hauv -Al₂O₃ tom qab calcination) tau dhau los ua cov khoom siv rau hydrogenation catalyst txhawb vim muaj cov yam ntxwv hauv qab no:
1. High Specific Surface Area, Muab ib qho zoo tshaj Platform rau Active Component Dispersion
High-zoo pseudo boehmite tuaj yeem ua tiav thaj chaw tshwj xeeb ntawm 260-350 m² / g lossis ntau dua tom qab calcination.
Qhov siab tshwj xeeb ntawm thaj chaw ua kom ntseeg tau tias cov khoom siv hlau ua haujlwm tau tawg heev ntawm nanoscale, txhim kho catalytic efficiency.
Rau cov khoom siv hlau muaj txiaj ntsig zoo, kev sib cais siab ncaj qha los txo cov nqi hlau siv thiab txuag nqi.
2. Tsim nyog Pore Structure, ua tau raws li cov kev xav tau ntawm cov khoom sib txawv ntawm qhov ntau thiab tsawg
Lub pore ntim thiab pore loj ntawm pseudo boehmite tuaj yeem tswj tau los ntawm cov txheej txheem ntau lawm.
Small- hom pore: Haum rau me me - cov tshuaj tiv thaiv kab mob xws li naphtha hydrogenation thiab distillate hydrogenation.
Loj - hom pore: Haum rau cov xwm txheej uas qhov kev nthuav dav ntawm cov molecules loj yog qhov tseem ceeb, xws li cov roj hnyav hydrogenation thiab residue hydrogenation.
3. Zoo heev Peptizability thiab Formability
Pseudo boehmitemuaj peev xwm tsim ib tug ruaj khov sol nyob rau hauv acidic tej yam kev mob, imparting zoo formability rau lub catalyst.
Hauv kev tsim cov txheej txheem xws li extrusion, roj poob, thiab tshuaj tsuag granulation, pseudo boehmite ua raws li cov ntaub ntawv los muab cov khoom siv dag zog.
Cov catalyst tiav lawm nthuav tawm lub zog siab compressive thiab kev puas tsuaj, ua kom haum rau cov reactor sib txawv xws li cov txaj ruaj thiab ebullated txaj.
4. Tunable Surface Chemical Properties
Lub acidity/basicity ntawm qhov chaw txhawb nqa cuam tshuam rau cov hlau -txhawb kev sib cuam tshuam thiab txoj hauv kev catalytic.
Cov khoom saum npoo tuaj yeem ua kom zoo ntxiv los ntawm kev hloov kho (xws li, qhia Si, Ti, P thiab lwm yam khoom ntxiv).
II. Indicator Requirements for Pseudo Boehmite in Hydrogenation Catalysts
Cov txheej txheem sib txawv ntawm cov txheej txheem hydrogenation muaj qhov sib txawv loj heev rau pseudo boehmite. Cov hauv qab no yog cov cim tseem ceeb ntawm Zibo Xiangrun thiab lawv qhov cuam tshuam:
|
Qhov taw qhia |
Hom kab mob |
Kev cuam tshuam rau Catalyst Performance |
|
Na₂O Content |
＜0.05% (siab- qib purity) |
Sodium yog cov tshuaj tua kab mob uas txo cov kev ua haujlwm thiab ua rau cov pa roj carbon deposition. Tsawg- cov khoom siv sodium yog qhov tsim nyog rau siab -kawg hydrogenation catalysts. |
|
Qhov chaw tshwj xeeb |
260-350 m²/g |
Muaj feem xyuam rau dispersion ntawm active hlau. Siab dhau yuav ua rau txo qhov pore ntim, yuav tsum tau sib npaug. |
|
Pore Volume |
0.3-1.2 cm³ / g |
Txiav txim siab diffusion efficiency ntawm loj molecules. Hnyav roj hydrogenation yuav tsum muaj cov khoom ntim pore siab. |
|
Peptizability Index |
＞97% |
Muaj feem xyuam rau formability thiab catalyst zog. |
|
Cov impurities (Fe, SiO₂, thiab lwm yam) |
＜0.03% |
Cov impurities tuaj yeem ua rau muaj kev cuam tshuam sab lossis ua rau catalyst deactivation. |
