Kev ntaub ntawv khoom Introduction:
Nws yog ua los ntawm molding thiab calcification txheej txheem, nrog rau siv lead ua theem ntawm γ-Al2O3 los yog α- Al2O3. Nws yog yus tsawg puas, nqaim particle loj tis (20-130μm), thiab zoo conglobation, uas yog tus kheej cai los ntawm lub tshuab kuaj kab. Nws yog lug siv raws li tus catalyst cab kuj nyob rau hauv petrochemical kev lag luam.
