Mu Makolero Ki Ebikozesebwa Ebikozesebwa Mu Byuma Ebiyitibwa Precious Metal Catalysts?
Ebirungo ebiziyiza ebyuma eby’omuwendo bikola kinene nnyo mu nkola z’amakolero olw’obutonde bwabyo obw’enjawulo obw’okutabula n’okutebenkera. Mu kulongoosa amafuta g’amafuta, bye bisumuluzo mu kulongoosa mu ngeri ya catalytic, alkane ne aromatic isomerization, n’okukola dehydrogenation reactions, okulongoosa ennyo enkola y’okukola obulungi n’okulonda ebivaamu. Mu kukola olefin, zikozesebwa okukola hydrogenation okulonda, okukakasa obulongoofu n’omutindo gw’ebintu ebikolebwa olefin.
Ebiziyiza ebyuma eby’omuwendo kyenkanyi tebyetaagisa mu kukola ebigimusa eby’eddagala ery’obutonde. Okukola ebigimusa ebikulu eby’eddagala nga ethylene oxide, acetaldehyde, ne vinyl acetate byonna byesigamye ku kikolwa ky’okutabula kw’ebirungo ebiziyiza ebyuma eby’omuwendo. Ebirungo bino ebizimba tebikoma ku kulongoosa bulungibwansi bwa kukola wabula era bikendeeza ku nsaasaanya y’okufulumya, ne bireeta emigaso mingi mu by’enfuna eri amakolero g’eddagala.
Okukuuma obutonde kye kitundu ekirala ekikulu eky’okukozesa ebirungo ebiziyiza ebyuma eby’omuwendo. Mu kwokya ggaasi ezitali nnungi mu ngeri ey’ekirungo (catalytic combustion of organic waste gases) n’okuziyiza (catalytic oxidation) kw’amazzi amakyafu ag’amakolero, ebirungo ebiziyiza ebyuma eby’omuwendo bisobola bulungi okukendeeza ku kufuluma kwa ggaasi ez’obulabe, ne bikuuma obutonde bw’ensi. Okugeza, mu kulongoosa omukka gw’emmotoka, ebirungo bya palladium ne platinum mu ngeri ssatu-ebikyusa omukka bisobola okukyusa ggaasi ez’obulabe okufuuka ebintu ebitali bya bulabe, ne kirongoosa nnyo omutindo gw’empewo.
Ekirala, ebiziyiza ebyuma eby’omuwendo nabyo biraga obusobozi obw’amaanyi obw’okukozesa mu kifo ky’amasoboza amapya. Nga ebintu ebikulu mu butoffaali bw’amafuta ga haidrojeni n’ebyuma ebikola haidrojeni mu kusengejja amasannyalaze g’amazzi, ebiziyiza ebyuma eby’omuwendo bikola kinene nnyo mu kuvuga enkulaakulana ya tekinologiya omupya ow’amasoboza.
Mu makolero g’eddagala n’eddagala ly’ebiwuka, ebyuma ebikola ebyuma eby’omuwendo nabyo bikozesebwa nnyo. Zikozesebwa mu kukola eddagala n’akawoowo, wamu n’okukola ebirungo eby’omu makkati eby’eddagala ly’ebiwuka. Ebirungo ebiziyiza Rhodium bikola bulungi nnyo mu kusengejja ebintu ebisookerwako eby’eddagala, akawoowo, n’okusiiga, ate ebirungo bya palladium bikozesebwa nnyo mu nkola z’okusengejja ebiramu.
Mu by’eddagala eddungi n’ebintu ebipya eby’eddagala, ebirungo ebiziyiza ebyuma eby’omuwendo nabyo bikola kinene nnyo. Zikozesebwa mu kukola ebirungo ebiri wakati wa kirisitaalo ow’amazzi, langi, ne langi, ekivuga enkulaakulana ey’amangu ey’amakolero gano. Mu kiseera kye kimu, olw’okumanyisa obutonde bw’ensi okweyongera, waliwo obwetaavu obw’amaanyi obw’ebirungo ebiziyiza ebyuma eby’omuwendo mu bizigo ebitayamba obutonde bw’ensi ne mu kukyusa ebirungo ebiriwo n’ebikozesebwa ebirala ebitali bya bulabe eri obutonde era ebitaliiko bulabe.
