Platinamu palladium wamtengo wapatali zitsulo chothandizira ndi kothandiza kwambiri zinyalala gasi chothandizira chithandizo, wapangidwa ndi Pt ndi Pd ndi zitsulo zina zamtengo wapatali, choncho ali mkulu kwambiri chothandizira ntchito ndi selectivity.Ikhoza kusintha bwino zinthu zovulaza mu gasi wotulutsa mpweya ndikuwasandutsa zinthu zopanda vuto, potero kuchepetsa utsi wa mpweya wotulutsa mpweya ndikuteteza chilengedwe ndi thanzi laumunthu lomwe timadalira.
Pachimake zigawo zikuluzikulu za platinamu ndi palladium chothandizira ndi zitsulo zamtengo wapatali monga platinamu ndi palladium, ndi kusankha zitsulo zamtengo wapatali zimenezi makamaka makamaka, kwathunthu malingana ndi ntchito zochitika za chothandizira ndi zofunika anachita chothandizira.Nthawi zambiri, kuchuluka kwa platinamu ndi palladium mu platinamu ndi palladium catalysts ndi 1: 1 kapena 2: 1, ndipo chiŵerengerochi chikhoza kukwaniritsa zotsatira zabwino kwambiri.Kuonjezera apo, chithandizo cha platinamu palladium chothandizira ndi chofunikira kwambiri, chomwe chimakhudza kwambiri ntchito ya chothandizira.Zonyamulira wamba ndi aluminium oxide, silicon oxide, yttrium oxide, ndi zina zambiri, zomwe zimapereka gawo lokhazikika la chothandizira ndikuwonetsetsa kuti zimathandizira kwambiri.
Njira zopangira zopangira platinamu ndi palladium zimaphatikizira kulowetsedwa, kunyezimira, mpweya, kusakanikirana kwakuthupi ndi zina zotero.The impregnation njira ndi impregnate chonyamulira zoipa (kawirikawiri okusayidi) mu njira munali platinamu ndi palladium ayoni, ndiyeno kukumana ntchito zingapo monga kuyanika ndi kuchepetsa, ndipo potsiriza kupeza platinamu ndi palladium chothandizira.The coprecipitating njira ndi kuti chonyamulira zoipa ndi platinamu ndi ayoni palladium akuwonjezedwa ku dongosolo anachita pamodzi, ndi ayoni platinamu ndi palladium ndi precipitated pamodzi padziko chonyamulira zoipa kupanga platinamu ndi palladium chothandizira ndi kulamulira pH mtengo ndi. kutentha kwa yankho.The platinamu palladium chothandizira akalandira njira imeneyi ali ndi makhalidwe a ntchito mkulu, selectivity mkulu ndi bata mkulu, amene amaonetsetsa dzuwa ndi chitetezo cha zinyalala mankhwala mankhwala.
Pogwiritsira ntchito platinamu ndi palladium zopangira zitsulo zamtengo wapatali, tiyenera kusamala zachitetezo.Choyamba, m'pofunika kupewa zinthu zoopsa monga lawi lotseguka, kutentha kwakukulu ndi magetsi osasunthika, zomwe zingayambitse kuwonongeka kwa ntchito zothandizira komanso ngakhale ngozi.Kachiwiri, chothandiziracho chiyenera kuyang'aniridwa ndikusinthidwa pafupipafupi kuti zitsimikizire kuti zimagwira ntchito bwino komanso kuti zitheke bwino.
