Hadhaaga habka daaweynta biyaha-kaaliyayaasha cayriin ee boehmite been abuur ah

Hadhaaga habka daaweynta hydrotreating sifooyinka habka daaweynta hydrotreating hadhaaga oo leh sariir go'an ayaa la bartay oo la soo koobay, astaamaha soo socdana waa la soo koobay: Marka hore, sariirta falcelinta kala duwan ama qaybaha kala duwan ee isla sariirta waxaa jira farqi u dhexeeya 1) falcelinta hydrotreating waa falcelinta kulaylka dibadda, falgalka warshadaha, kororka heerkulka ee isla sariirta, lakabka sariirta 2) heerkulka falcelinta hoose waa walax falcelin sare leh meesha ugu horeysa ee qaybta sare ee sariirta ama falcelinta sariirta koowaad, iyo walxaha falcelinta ee salka hoose ee sariirta ama falcelinta sariirta ee xigta 3) fiirsashada falgalka sariirta sare ayaa ka sarreysa, iyo fiirsashada falgalka salka hoose ee sariirta ayaa hooseysa ama beddelka falgalka sariirta sare ayaa ka sarreeya, culaysku waa ka weyn yahay 4) falcelinta hydrotreating iyo soo saarista hydrogen sulfide iyo ammonia, isticmaalka hydrogen sababta sariirta sare iyo lakabka hoose ee fiirsashada H2 ee H2S iyo NH3 kala duwan labaad, saliidda haray waxay ka kooban tahay xaddi badan oo wasakh ah iyo qaybo aan ku habboonayn, celcelis ahaan miisaankeeda molecular, viscosity sare, taasoo horseedaysa waxqabad falcelin hooseeya, joojinta kicinta, sidaas darteed habka daaweynta hydrotreating hadhaaga xaaladaha hawlgalka oo dalbanaya, cadaadis sare iyo heerkulka, xawaaraha booska oo hooseeya saddexaad, hadhaaga laga soo saaro habka hydrogenation-ka sariirta ee go'an oo ka badan coke iyo bir sulfide iyo walxo kale oo adag, dhigista adag ee sariirta waxay sababi doontaa in farqiga cadaadiska sariirta uu kordho ilaa xadka naqshadeynta la gaaro, qalabkana lagu qasbay inuu xiro Afaraad, habka hydrotreating-ka haraaga ah waa inuu qaataa tignoolajiyada isku-darka kicinta
