Denstone® Support Media

Saint-Gobain NorPro is the world leader in ceramic fixed catalyst bed support technology and has set the industry standard with its Denstone® support media.  Denstone support media is utilized in petrochemical, refining and chemical plants all around the world.

Saint-Gobain NorPro provides an extensive range of Denstone® brand ceramic bed support media, including Denstone 2000, 99, 57, along with it's revolutionary bed support technology -- Denstone® deltaP® media for fixed bed applications. The Denstone deltaP engineered media is unlike any traditional spherical bed support media and can increase the performance of your reactor.  This technological breakthrough offers multiple benefits, improving your overall operating performance and bottom line results. 

Unsurpassed Product Benefits

Will not plug bed or catalyst
NorPro® Denstone® patented support media technology ensures seamless, monolithic spheres which eliminates splitting and spalling. 
Benefit:   Plugging of the catalyst bed is prevented, optimizing the process efficiency by keeping the pressure drop low and the catalyst activity high.

Will not contaminate
Denstone media are engineered to maximize resistance to erosion and attrition and thus minimize the possibility of catalyst contamination. 
Benefit:   Contamination of catalyst is prevented, extending the catalyst's active life and reducing operating costs.

High thermal shock resistance
Unique NorPro technology yields support media with a high thermal shock resistance.
Benefit:  Denstone supports will retain their physical properties when exposed to thermal cycling. Poor quality spheres will break, chip or spall, leading to adverse process efficiency and increased operating costs.

Will not poison catalyst
Denstone support media are free of sulfur, boron and other common catalytic poisons.  Manufactured Denstone media have a leachable iron content of less than 0.1%.  Analysis of Denstone media boiled in 10% hydrochloric acid for 64 hours indicate a leachable iron content of less than 0.005% by weight.  In each case, the iron content is expressed as Fe2O3.  Tests establish that leachable chlorides and sulfur are each less than 1 ppm by weight for both crushed and uncrushed Denstone media. 
Benefit:   No catalyst poison is introduced to the process, allowing the catalyst to perform optimally and thus avoiding severe cost implications such as plant shut downs, catalyst replacement and reinstallation and loss of throughput.

Denstone Support Media -- Pressure Drop Estimator

Pressure drop is an important measure in performance of catalyst bed support media.  Saint-Gobain NorPro makes it easier for you to determine the pressure drop for your particular application.  The estimator allows you to enter information such as sphere diameter, gas velocity, operating pressure, and operating temperature.  The estimator then calculates pressure drop.
