Iyada oo alumina ay tahay side, nikkel-ku uu yahay qaybta ugu firfircoon, kaaliyayaasha waxaa si weyn loogu isticmaalaa gaaska hawada ee duulista ilaa hydrogenation dearomatization, hydrogenation benzene ilaa cyclohexane, hydrogenation phenol ilaa cyclohexanol hydrotreating, hydrofining ee hexane cayriin warshadaha, iyo hydrogenation organic ee hydro-carbons aliphatic aan dheregsanayn iyo hydrocarbons aromatic, sida saliidda cad, hydrogenation saliidda saliidaha. Waxa kale oo loo isticmaali karaa desulfurization hufan marxaladda dareeraha ah, iyo wakiilka ilaalinta sulfur ee habka dib-u-habaynta catalytic. Kaaliyayaasha waxay leeyihiin xoog sare, firfircooni aad u fiican, habka sifeynta hydrogenation, kaas oo ka dhigi kara hydrocarbon aromatic ama aan dheregsanayn heerka ppm. Kaaliyayaasha waa xaalad la dhimay oo ah daaweynta xasilinta.
Marka la barbardhigo, kiciyeyaasha si guul leh loogu isticmaalay daraasiin dhir ah oo adduunka ah, ayaa ka wanaagsan wax soo saarka gudaha ee la midka ah. Sifooyinka jirka iyo kiimikada:
