Indlela yokusabela kumphezulu (RSM) yasetyenziselwa ukufunda inkqubo ye-nitric acid leaching yenkunkuma ye-Co Mo esekelwe kwi-hydrotreating catalyst. Injongo yolu phononongo yayikukuzisa i-CO kunye ne-Mo ukusuka kwi-catalyst echithwe kwi-solvent ngendlela ye-soluble yamanzi, ukwenzela ukuba kube lula ukuhlanjululwa kunye nokubuyisela kwakhona, kunye nokuqonda unyango olungenabungozi kunye nokusetyenziswa kobutyebi benkunkuma eqinileyo, i-Reaction. ubushushu kunye nomlinganiselo oqinileyo-ulwelo. Izinto eziphambili eziphembelelayo zichongwe yindlela yokuphendula, kwaye imodeli ye-equation yeeparamitha zenkqubo kunye ne-cobalt kunye ne-molybdenum leaching rate yasekwa. Ngaphantsi kweemeko zenkqubo efanelekileyo efunyenwe ngumzekelo, izinga le-cobalt leaching lingaphezulu kwe-96%, kwaye izinga le-molybdenum leaching lingaphezulu kwe-97%. Ibonise ukuba iiparameters zenkqubo efanelekileyo efunyenwe ngendlela yempendulo yomphezulu ichanekile kwaye inokuthenjwa, kwaye ingasetyenziselwa ukukhokela inkqubo yokuvelisa eyona nto.
