In addition to being very energy intensive, operating at such temperatures can cause a buildup of unwanted deposits, a phenomenon known as coking, which reduces the lifetime of the catalyst.

Propane dehydrogenation is a key industrial route to producing propylene without relying on oil. However, its current ...

Coke fines are the single largest type in a ... Inorganic fines are FCC catalyst, ebullated-bed catalyst fines, corrosion deposits, bitumen sand, and other 100µ solids entering the coker via ...

Catalysts are materials that help to foster and speed up reactions without being used up in the process, and coke deposits in zeolites are a costly problem in petroleum refinement and in ...

The other is the formation of coke -- basically solid carbon that blocks the catalyst from contacting the reactants." Catalysts work by providing a large surface area for reactions. Metal atoms ...

Swihart explains that dry reforming of methane isn’t commercially viable using existing nickel-based catalysts, which stop functioning because their catalytically active particles become covered with ...
