How do catalytic converters work? - Explain that Stuff
2022年2月18日 — Inside the converter, the gases flow through a dense honeycomb structure made from a ceramic and coated with the catalysts. The honeycomb structure means the gases touch a bigger area of catalyst at once, so they are converted more quickly and efficiently.
Honeycomb structure and catalytic converter - Google Patents
A catalytic converter has a honeycomb catalyst body, a housing and a holding material, wherein the honeycomb catalyst body has, as the catalyst carrier, a honeycomb structure having an...
7.1: Catalytic Converters - Chemistry LibreTexts
2023年8月20日 — A catalytic converter is a device used to reduce the emissions from an internal combustion engine (used in most modern day automobiles and vehicles). Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide and water; thus toxic by-products are produced.
Catalytic Converter Substrate: Types, Functions & Maintenance
2024年1月25日 — What Is the Significance of the Honeycomb Structure in Catalytic Converter Substrates? The honeycomb structure maximizes surface area, promoting efficient contact between exhaust gases and catalyst materials. This design enhances the catalytic conversion process within the converter.
Catalytic Converters Parts: Examination of Internal Parts and …
2023年11月20日 — Most modern catalytic converter substrates leverage a honeycomb configuration, which provides significant performance advantages: The multi-channel honeycomb structure yields an extremely high surface area-to-volume ratio. More surface area within a given converter volume allows maximized catalytic activation.
Catalytic converter - Wikipedia
For automotive catalytic converters, the core is usually a ceramic monolith that has a honeycomb structure (commonly square, not hexagonal). (Prior to the mid 1980s, the catalyst material was deposited on a packed bed of alumina pellets in early GM applications.)
What Materials are Used in Catalytic Converters? - AZoM.com
The catalytic converter is made up of several materials. The catalyst core or substrate varies according to the vehicle. For example, when these devices are used in automobiles, the core is usually a ceramic monolith with a honeycomb structure. When manufactured in large quantities, ceramic cores can be inexpensive.
tried Catalytic convertor structure with spinel from the honey comb. By changing the structure the contact area and time of contact of exhaust gases with ceramic layer substrate.

2024年3月14日 — A catalytic converter is an exhaust emission control device that uses a catalyst to convert three harmful compounds in car exhaust. Monty Rakusen / Getty Images/Image Source. There are millions of cars on the road in the United States, and …
Structure of Catalytic Converters
2023年11月1日 — There are ceramic honeycombs in the catalytic converters. These honeycombs are covered with platinum group metals. With these metals, chemical reaction takes place and the incoming gases exit the exhaust after being cleaned.
