WebLead is a catalyst poison and would effectively destroy a catalytic converter by coating the catalyst's surface. Requiring the removal of lead allowed the use of catalytic converters to meet the other emission standards in the … WebNov 28, 2013 · Catalytic converters use metallic catalysts to promote the desired reactions at lower temperatures than would otherwise be needed. Typical values are shown in Figure 8.21.The catalyst types could be a base metal (e.g., copper, Cu, or chromium, Cr) but are more usually noble metal (platinum, Pt, palladium, Pd, rhodium, Rh). The transition metal … WebJun 10, 2024 · Catalytic converters use chemical reactions to remove harmful emissions from the exhausts of cars and vehicles, but as engines become more efficient, exhaust temperatures are reducing and the high temperature chemistry catalysts rely on isn’t working as well. There is also the ‘cold start’ problem, when the catalyst hasn’t warmed up … cheeto bread
