Our media shapes are engineered to maximize resistance to erosion and attrition and thus minimize the possibility of catalyst contamination. Denstone® material formulations are designed to be free of media sulfur, boron and other common catalytic poisons. Leachable Iron, chlorides, and sulfur can also be a poison to many catalysts, and are controlled through our material and process design. Denstone® 2000, 57, and deltaP® media have been developed to have a leachable iron (Fe2O3) content of less than 0.1 wt%, while our high alumina Denstone® 99 product has a maximum iron content of 0.20 wt%. Tests establish that leachable chlorides and sulfur are each less than 1 ppm by weight for both crushed and uncrushed Denstone media.
By ensuring that no catalyst poison is introduced to the process, your catalyst is able to perform optimally for its full expected life. Additionally, by avoiding severe upsets such as plant shut downs, catalyst replacement and reinstallation and loss of throughput, Denstone® support media allows you to minimize your operating costs and keep the unit producing.
Due to our engineered formulations, 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.
Denstone® support media from any of our three regional sites (United States, Germany, and China) are engineered to provide the same performance. Our processes are validated by external ISO 9001, ISO 14001, and OHSAS 18001 certification, to ensure that regardless of where you are located, Denstone® support media will give you the same high level of confidence and performance.
