Platinamu palladium yakakosha simbi inokonzeresa inonyatso shanda gasi kurapa gasi catalyst, inoumbwa nePt nePd nedzimwe simbi dzinokosha, saka ine yakanyanya kukwirira kuita uye kusarudza.Inogona kunyatso kushandura zvinhu zvinokuvadza mugasi rekuburitsa uye kuvashandura kuita zvinhu zvisingakuvadzi, nekudaro kuderedza kubuda kwegasi rekupedza uye kuchengetedza zvakatipoteredza uye hutano hwevanhu hwatinovimba nahwo.
Izvo zvakakosha zveplatinamu uye palladium catalysts simbi dzakakosha senge platinamu uye palladium, uye kusarudzwa kweaya anokosha masimbi akanyanya kunyanya, zvichienderana nekushandiswa kwechiitiko checatalyst uye zvinodiwa zvecatalytic reaction.Kazhinji, huwandu hwehuwandu hweplatinamu uye palladium muplatinamu uye palladium catalysts ndeye 1: 1 kana 2: 1, uye iyi reshiyo inogona kuita yakanakisa catalytic mhedzisiro.Mukuwedzera, kutsigirwa kweplatinum palladium catalyst inokoshawo zvikuru, iyo ine simba guru pakushanda kwechigadziridzo.Vatakuri vakajairwa aluminium oxide, silicon oxide, yttrium oxide, nezvimwewo, izvo zvinopa yakagadzikana substrate yecatalyst uye inova nechokwadi chekushanda kwakanyanya kunobatsira.
Iyo yakajairika nzira dzekugadzirira dzeplatinamu uye palladium catalysts dzinosanganisira impregnation, co-precipitation, kunaya, kusanganisa kwemuviri uye zvichingodaro.The impregnation nzira iri impregnate ane negative mutakuri (kazhinji oxide) kupinda mhinduro ine platinum uye palladium ions, uye ipapo kuitwa dzakatevedzana maoparesheni akadai kuomesa uye kuderedza, uye pakupedzisira kuwana platinum uye palladium catalyst.The coprecipitating nzira ndeyokuti negative mutakuri uye platinum uye palladium ions anowedzerwa kuti reaction hurongwa pamwe chete, uye platinum uye palladium ions ari precipitated pamwe pamusoro pepamusoro mutakuri zvakaipa kuti kuumba platinum uye palladium catalyst nokudzora pH ukoshi uye. tembiricha yemhinduro.Iyo platinum palladium catalyst yakawanikwa nenzira iyi ine maitiro ekushanda kwepamusoro, kusarudza kwepamusoro uye kugadzikana kwepamusoro, iyo inovimbisa kushanda uye kuchengetedzwa kwemarara gasi kurapwa.
Paunenge uchishandisa platinamu uye palladium yakakosha simbi inokonzeresa, isu tinofanirwa kutarisisa nyaya dzekuchengetedza.Chekutanga pane zvese, zvinodikanwa kudzivirira mamiriro ane njodzi senge murazvo wakavhurika, tembiricha yakanyanya uye static magetsi, izvo zvinogona kutungamira mukuipa kwekuita catalyst uye kunyangwe njodzi.Kechipiri, iyo catalyst inoda kuongororwa uye kuchinjwa nguva nenguva kuti ive nechokwadi chekushanda kwayo kwakajairika uye kuwana yakanakisa catalytic mhedzisiro.
