Kusintha kwa Catalytic ndi njira yofunika kwambiri pantchito yoyenga mafuta, yomwe cholinga chake ndi kukweza mtundu wa petulo. Mwa njira zosiyanasiyana zosinthira,Kubadwanso Kwatsopano kwa CatalystKusintha kwa (CCR) kumadziwika chifukwa chakuchita bwino komanso kuchita bwino popanga mafuta a octane apamwamba. Chigawo chachikulu cha ndondomekoyi ndi chothandizira kusintha, chomwe chimagwira ntchito yofunika kwambiri pothandizira kusintha kwa naphtha kukhala zigawo zamtengo wapatali za mafuta.
Ndi chiyaniKusintha kwa CCR?
Kusintha kwa CCR ndiukadaulo wamakono woyenga womwe umalola kusinthika kosalekeza kwa chothandizira chomwe chimagwiritsidwa ntchito pakukonzanso. Njirayi imasiyana ndi kusintha kwachikhalidwe kwa batch, komwe chothandizira chimachotsedwa nthawi ndi nthawi kuti chipangidwenso. Mu CCR kukonzanso, chothandizira chimakhalabe mu riyakitala, ndipo kusinthika kumachitika mu gawo losiyana, kulola kuti ntchito ikhale yokhazikika komanso yowonjezereka. Njira yopitilira iyi sikuti imangowonjezera zokolola zamafuta a octane apamwamba komanso imathandizira kuti ntchito yoyenga itheke.
Udindo wa Othandizira pa Kusintha
Catalysts ndi zinthu zomwe zimathandizira kusintha kwamankhwala popanda kugwiritsidwa ntchito. Pankhani yaKusintha kwa mtengo wa CCR, chothandizira ndi chofunikira pazochitika zingapo, kuphatikizapo dehydrogenation, isomerization, ndi hydrocracking. Zochita izi zimasintha ma hydrocarbons owongoka kukhala ma hydrocarbons a nthambi, omwe amakhala ndi ma octane apamwamba kwambiri ndipo amafunikira kwambiri popanga mafuta.
Zothandizira zomwe zimagwiritsidwa ntchito kwambiri pakusintha kwa CCR ndi zotengera zochokera ku platinamu, zomwe nthawi zambiri zimathandizidwa ndi aluminiyamu. Platinamu imayamikiridwa chifukwa chakuchita bwino komanso kusankhika polimbikitsa zomwe mukufuna. Kuonjezera apo, kugwiritsa ntchito chothandizira cha bifunctional, chomwe chimagwirizanitsa malo onse achitsulo ndi asidi, kumapangitsa kuti kutembenuka kwa naphtha kukhala kopambana kwambiri kumapanga octane. Malo azitsulo amathandizira kuti dehydrogenation, pomwe malo a asidi amalimbikitsa isomerization ndi hydrocracking.
Kodi Chothandizira Chotani Chimagwiritsidwa Ntchito mu Reformer?
Mu CCR kusintha, ndichothandizira choyambazomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala chothandizira cha platinamu-aluminium. Chothandizira ichi chapangidwa kuti chipirire mikhalidwe yovuta ya ndondomeko yokonzanso, kuphatikizapo kutentha kwakukulu ndi kupanikizika. Gawo la platinamu limayang'anira ntchito yothandizira, pomwe chithandizo cha aluminiyamu chimapereka kukhazikika kwadongosolo komanso kumtunda kuti zomwe zimachitikazo zichitike.
Kuphatikiza pa platinamu, zitsulo zina monga rhenium zitha kuwonjezeredwa kuti zithandizire kugwira ntchito. Rhenium imatha kupititsa patsogolo kukana kwa chothandizira kuti asagwiritsidwe ntchito ndikuwonjezera zokolola zonse zamafuta a octane apamwamba. Mapangidwe a chothandizira akhoza kusiyana malingana ndi zofunikira zenizeni za ndondomeko yoyenga komanso zomwe mukufuna.
Mapeto
Zothandizira kusintha, makamaka pakusintha kwa CCR, ndizofunikira pakupanga mafuta apamwamba kwambiri. Kusankhidwa kwa chothandizira, chomwe nthawi zambiri chimapangidwa ndi platinamu-alumina, chimakhudza kwambiri momwe ntchito yosinthira imagwirira ntchito. Pomwe kufunikira kwa mafuta oyeretsera komanso owoneka bwino kukupitilira kukwera, kupita patsogolo kwaukadaulo wothandizira kuthandizira kukulitsa tsogolo lopanga mafuta. Kumvetsetsa zovuta za zopangira izi ndi ntchito zake ndikofunikira pakuyenga akatswiri omwe cholinga chake ndi kukhathamiritsa ntchito zawo ndikukwaniritsa zomwe msika ukufunikira.
