A918 Activated Alumina Catalystrau kev rov qab los ntawm leej faj, nws tus kheej tsim los ntawm Shandong Xunda Chemical Group Co., Ltd., yog ib qho khoom siv tiv thaiv ib puag ncig tsim tshwj xeeb tsim rau siab - xav tau sulfur- muaj cov khoom siv roj pov tseg.
Noj siab -purity gamma- alumina ( -Al₂O₃) raws li tus neeg nqa khoom thiab nruab, cov khoom no tawg los ntawm cov kev txwv ntawm cov neeg nqa khoom ib txwm muaj. Kev cia siab rau qhov zoo tshaj plaws dispersibility thiab ruaj khov ntawm aluminium-raws li cov ntaub ntawv, nws ua tiav kev hloov pauv ntawm sulfides thiab kev rov qab los ntawm leej faj, muab kev lees paub ob zaug ntawm kev ua raws li cov qauv emission thiab kev siv peev txheej rau kev lag luam xws li petrochemicals thiab thee chemical engineering.
