Ke engPhetoho ea CCR?
Phetoho ea CCR ke theknoloji ea morao-rao ea ho hloekisa e lumellang ho tsosolosoa ho tsoelang pele ha mokelikeli o sebelisoang ts'ebetsong ea ntlafatso. Mokhoa ona o fapana le phetoho e tloaelehileng ea batch, moo catalyst e tlosoang nako le nako bakeng sa nchafatso. Ho ntlafatso ea CCR, mokelikeli o ntse o le ka har'a mochine, 'me ho tsosolosoa ho etsahala karolong e fapaneng, e lumellang hore ho be le ts'ebetso e tsitsitseng le ho feta.

Karolo ea Li-Catalyst ho Phethahatsong
Li-Catalysts ke lintho tse potlakisang ts'ebetso ea lik'hemik'hale ntle le ho sebelisoa nakong eo. Boemong baHo fetola CCR, catalyst ke ea bohlokoa bakeng sa liketso tse 'maloa, ho akarelletsa le dehydrogenation, isomerization, le hydrocracking. Lits'ebetso tsena li fetola li-hydrocarbon tse otlolohileng ho li-hydrocarbons tsa branched-chain, tse nang le litekanyetso tse phahameng tsa octane 'me li lakatseha haholoanyane mekhoeng ea peterole.
Li-catalyst tse sebelisoang ka ho fetisisa ho ntlafatso ea CCR ke li-catalyst tse thehiloeng ho platinum, tse atisang ho tšehetsoa ka alumina. Platinum e ratoa ka lebaka la ts'ebetso ea eona e ntle haholo le boikhethelo ba ho khothaletsa karabelo e lakatsehang. Ho phaella moo, tšebeliso ea li-catalyst tse peli, tse kopanyang libaka tse peli tsa tšepe le tsa acid, li lumella hore ho be le phetoho e ntle ea naphtha ho lihlahisoa tse phahameng tsa octane. Libaka tsa tšepe li nolofatsa dehydrogenation, ha libaka tsa acid li khothalletsa isomerization le hydrocracking.
Ke Catalyst Efe e Sebelisitsoeng ho Reformer?
Ho ntlafatso ea CCR, homothusi oa mantlhae sebelisoang hangata ke sesebelisoa sa platinamo-aluminium.

Qetello
Li-catalysts tsa phetoho, haholo-holo tabeng ea ho fetola CCR, ke karolo ea tlhahiso ea peterole ea boleng bo phahameng. Khetho ea catalyst, eo hangata e leng sebopeho sa platinamo-aluminium, e ama haholo ts'ebetso le katleho ea ts'ebetso ea ntlafatso. Ha tlhokahalo ea libeso tse hloekileng le tse sebetsang hantle li ntse li eketseha, tsoelo-pele ea mahlale a khothatso e tla bapala karolo ea bohlokoa ho bopeng bokamoso ba tlhahiso ea peterole. Ho utloisisa ho rarahana ha li-catalyst tsena le mesebetsi ea tsona ho bohlokoa bakeng sa ho nchafatsa litsebi ka sepheo sa ho ntlafatsa ts'ebetso ea tsona le ho fihlela litlhoko tse ntseng li tsoela pele tsa mmaraka.
