Pd Nneɛma a Ɛsom Bo a Wɔde Yɛ Nneɛma

Dade a ɛsom bo a ɛma nneɛma yɛ kɛse de dade a ɛsom bo a wɔde kata platinum, palladium, ne rhodium so wɔ dɔte a wɔde yɛ ɛwo so di dwuma de nnuru dan mframa a epira a efi mu ba no ma ɛbɛyɛ nneɛma a epira kɛse,ɛwo nhyehyɛe no ani a ɛkorɔn no ma dade a ɛsom bo no tumi ma nneɛma a ɛsom bo no tumi yɛ nneɛma te sɛ carbon monoxide a wɔdan no carbon dioxide ne hydrocarbons ma ɛbɛyɛ nsu ne carbon dioxide yiye. Ɛsono sɛnea dade a ɛsom bo pɔtee a wɔaka abom ne dodow a wɔde di dwuma no gyina kar no ne ne mframa a wɔtow gu no gyinapɛn ahorow so, na ne bo ma ɛyɛ nea wɔde awia nneɛma na wɔsan de di dwuma bio.

• Dadeɛ a Ɛsom Boɔ a Ɛma Nneɛma Yɛ Adwuma a Ɛma Nneɛma Yɛ Fɛ: Dadeɛ a ɛsom bo te sɛ platinum ne palladium yɛ adwuma sɛ nneɛma a ɛma nneɛma yɛ adwuma, na ɛhyɛ nnuru a ɛyɛ adwuma ase na ɛma ɛyɛ ntɛmntɛm a wɔmfa nni dwuma.
• Precious Metal Catalyst Reaction process: Sɛ mframa a efi mu ba no fa ɛwo a wɔde akata so no so a, catalysts no kanyan reactions. Sɛ nhwɛso no, carbon monoxide yɛ oxidized ma ɛbɛyɛ carbon dioxide (CO2),ne hydrocarbons(CxH2x+2)yɛ oxidized ma ɛbɛyɛ carbon dioxide (CO2)ne nsu(H2O).
• Precious Metal Catalyst Structure: Wɔde dadeɛ no kata ceramic anaa metal monolith so a ɛwɔ structure a ɛte sɛ ɛwoɔ-, a ɛma beaeɛ kɛseɛ a ɛwɔ soro ma reactions no kɔ so yie.
• Precious Metal Catalyst Adwumayɛ hyew: Nneyɛe no hwehwɛ sɛ converter no du adwumayɛ hyew a ɛkorɔn, bɛyɛ 300∘

• Platinum a wɔde yɛ adwuma (Pt):Wɔde di dwuma sɛ ade a ɛma nnuru yɛ adwuma ntɛmntɛm.
• Palladium a wɔfrɛ no Palladium (Pd):Ɛne platinum yɛ adwuma de boa ma wɔdan mframa a epira ma ɛbɛyɛ nea epira kɛse.
• Rhodium a wɔfrɛ no Rhodium (Rh):Wɔde di dwuma titiriw de tew nitrogen oxides (NOx) so kɔ nitrogen gas (N2) ne oxygen(O2) mu wɔ akwan abiɛsa-catalytic converter mu.
