There are three different types of Cat-Cons. The first type is the oxidation catalyst. It reduces harmful pollutants such as carbon monoxide (CO) and fuel hydrocarbons (HC) in the exhaust. Simultaneously, it often uses a secondary air injection. However, the oxidation catalyst only reduces a ...
Chemical kinetics is the division of physical chemistry that deals with the rates of a chemical reaction as well as the pathways through which a chemical reaction occurs. There are many factors which affect the rate of chemical reaction, catalyst is one of them....
In this work, we show that finding and controlling optimum pH environments with Pt-based alloy catalysts can create high catalytic performances for electrocatalytic glycerol oxidation reaction (EGOR). Compared to a Pt/C catalyst, the PtCu/C alloy catalyst has higher reaction rate and turnover ...
Oxidation of Alcohol If you strip off hydrogens from the right carbon of ethanol in the presence of oxygen, you get acetic acid, the main component in vinegar. The molecular structure of acetic acid looks like this: where C is carbon, H is hydrogen, O is oxygen, the hyphen is a single...
In the catalytic converter, there are two different types of catalyst at work: a reduction catalyst and an oxidation catalyst. Both types consist of a ceramic structure coated with a metal catalyst, usually platinum, rhodium and/or palladium. The idea is to create a structure that exposes the...

As an antioxidant, vitamin E can help prevent the oxidation of LDL cholesterol, which can damage arteries. More heartening news: Seeds are a good source of folic acid. Researchers have found that folic acid helps prevent the buildup of homocysteine. High levels of this amino acid have been ...
13 - NOx Sensor 14 - PM Sensor 15 - DEF Tank 16 - SCR Catalyst 17 - DPF 18 - DOC How does an aftertreatment system work? The harmful emission gases in the exhaust stream move from the exhaust side of the turbo to the aftertreatment system (outlined in red). ...
Removing the battery and allowing these gases to recombine on the platinum catalyst generates electricity, creating a basic model of a hydrogen fuel cell. Ah, the hydrogen fuel cell. It's one of the most promising renewable energy technologies out there—it can generate electricity pollution-free...
oxidation catalyst, selective catalytic reduction catalyst, diesel particle filter, wet scrubber) in combination with high-quality fuels, accompanied with (stricter) emission standards, coastal residents and the marine ecosystem would profit likewise. Based on our results we emphasize that the wet ...
