Inta badan kicinta hydrogenation ee side catalyst alumina marka hore alumina oo leh dhibic dab-shid sare, dhibic dhalaal sare, taas oo tilmaamaysa inay tahay nooc ka mid ah oksaydh-celiyaha, sida sameynta walxaha kiciyaha walxaha yaryar ee aadka u kala firirsan oo ka soocan midba midka kale, si looga fogaado isu-ururinta side catalyst ama sintering labaad, alumina marxaladda waxay ku jirtaa heerkul ballaaran, waxayna ka dhigtaa qaab-dhismeedkeeda gudaha heerkul sare marka dib-u-habaynta kiristaalku ay xasilloon tahay heerkul sare, xirashada iska caabbinta, waxqabadka wareejinta kulaylka wanaagsan marka lagu daro, jiritaanka fal-celinta aashitada dusha sare ee alumina iyo xarunta alkaline sida acid ee dhexdhexaadka alkaline, iyo kaas oo ka fal celin kara sida alkali ee dhexdhexaadka aashitada. Sidaa darteed, side catalyst alumina, waxay leeyihiin taageero iyo kala firdhinta biraha qaaliga ah waxay khafiifisaa saameynta waxayna ka dhigtaa qaybinta dusha sare ee birta ee cabbirka hadhuudhka yar ee la metastable inuu noqdo mid deggan, ma fududa in la ururiyo oo sintering-ku xitaa waa muhiim maadaama oksaydhka aluminium ee alumina, aluminium miiska iyo dhaqaaqa, sameysma oksaydhyada oo ka tago god, oo leh jajabka madhan ee sare iyo kayd badan, waxaa lagu hagaajin karaa qaybaha catalytic booskeeda gudaha, waxayna ku habboon tahay in lagu faafiyo xarunta firfircoon ee fal-celinta iyo alaabada ka tageysa bartamaha firfircoon oo dhan. Kuwaas waxay muujinayaan in alumina ay leedahay waxqabad aad u wanaagsan oo ah side-ka kiciyaha.
