A catalytic converter is a key emissions control device. A car's exhaust contains several harmful gases, including carbon monoxide (CO), nitrogen oxides (NO x ), and volatile organic compounds (VOCs)/hydrocarbons. A catalytic converter uses palladium, rhodium, and platinum to create a chemical reaction that reduces those gases.

Industrial recycling of catalytic converters typically starts with. dismantling (decanning) the ceramic monolith using guillotine shears; breaking down the ceramic to smaller pieces in hammer mills connected by a closed tubing system; milling the material to dust in a ball-mill blender; You might want to wear a filter mask during these steps.

A catalytic converter reduces the emissions from the engine's exhaust by means of a chemical reaction. If you split the assembly in half, you'll have two primary sections. Most vehicles have two converters – one near the engine (the light-off that handles NOx). This one is monitored for efficiency by a downstream O2 sensor.

According to data from 2020, the most expensive catalytic converter belonged to the Ferrari F430, with a mind-popping $3,770.00 price tag. Moreover, the F430 needed two of them, so a full replacement would run car owners $7,540 before labor costs. While the Lamborghini Aventador's converter is technically the third most expensive, at …

Ball-milling has been also combined with pyrolysis to further improve surface area and porosity of the resulting materials. The ball mill effects on catalyst morphology and overall performance depend on temperature, milling time and rotation rate, and catalyst/carbon ratio [24,37,39,41,42,43,44,45].

The catalytic conversion of CO 2 to fuels and organic chemicals is a key CCU measure [ 6] that reduces CO 2 to various compounds, such as methane (CH 4) [ 7 ], formic acid and formates (HCOOH and HCOO −, respectively) [ 8 ], and methanol (CH 3 OH) [ 9 ]. In this conversion process, catalysts play a crucial role in catalyzing reactions.
