Application of Infrared honeycomb ceramic plate

Honeycomb ceramics used for catalytic cracking are replacing existing products. 

Catalytic cracking uses heavy distillate oil between 200 and 500 ° C as raw materials (including vacuum distillate, 

straight-run light diesel, coking wax oil, etc.), uses aluminosilicate as catalyst, and the reaction temperature is 

between 450 and 550 ° C (depending on the type of reactor). It has a large output (each large catalytic 

cracking unit cracks more than one million tons of oil products per year) and high technical requirements (for example, 

the catalyst needs to be regenerated every few minutes or even seconds after contacting the oil, and 

10 tons or more of the fluidized bed catalyst flows through the fluidized bed per minute). With the increase of 

catalytic activity, more stringent regeneration conditions are required to speed up the regeneration speed. 

For example, at 600-650 ° C, or even 700 ° C, the catalyst consumption is large, 0.3-0.6 kg of catalyst is 

consumed per ton of feed oil, and the catalyst with poor mechanical strength consumes much more. 

This requires a slight improvement in catalyst activity, selectivity, and stability, which will be of great 

significance to actual production. Because of this, honeycomb ceramic catalysts are constantly being innovated, 

and the market demand is also increasing. These catalysts used for catalytic cracking are replaced by honeycomb 

ceramic catalysts. Honeycomb ceramic catalysts with large size and multiple pores have emerged and have a strong 

development momentum.

The honeycomb ceramics of infrared honeycomb ceramic plates have the following advantages as filter materials: 

good chemical stability, acid and alkali resistance and organic solvent resistance; excellent resistance to rapid heating and cooling, 

the working temperature can be as high as 1000℃; good performance, not easy to be degraded, not easy to be blocked and easy 

to regenerate; strong structural stability, narrow pore size distribution, high permeability; non-toxic, especially suitable for food 

and heat treatment.
