1.standard dimension HQ-MH porous ceramic ball、ceramic column, there are *2 assortments on every 5% as a grade in accordance with the AL**3 content from *5% to *0%. They are Divided into *2 specifications according to diameter rsizes: Φ3 , Φ6 , Φ8 , Φ*0 , Φ*3, Φ*6 , Φ*0 , Φ*5 , Φ*0 , Φ *8 , Φ*0, Φ*5. Further, we also can produce according to the customers’ requirements. Therefore, it can play the roles of covering or supporting the catalyst, and separating the gas and liquid. At the same time, there is ****0% pore volume of structure increased, which has the adsorbing capacity, so that it may be utilized to the impurities filtrating in the oil. As there are such filtrating equipment, there are rather some of the impurities remained( such as <*5μm granular impurities and ferrous ions). If the porous ceramic ball is loaded on the top of the reactors, the impurities, which is still remained through the raw material filtrating equipment, can be adsorbed in its pores, therefore, the catalyst is protected and the under-stream period is guaranteed.According to the kind of raw material impurity when hydrotreating、hydrogen production and reformer, different content and grain size, users can choose different diameter and hole count porous ceramics ball, also can according to the requirements, attach PBTCA as Mo、nickel、cobalt etc, in order to prevent the Carbon anti-coking and poisoning of the catalyst. ***** TECHNICAL PARAMETERS technical index kind performance HQ-MH*1 HQ-MH*2 HQ-MH*3 Chemical Composition % Al2O3 ****0 Al2o3+SiO2 ≥*0 Fe2O3 ≤1 aperture， um 0.***5 **- **0 *******0 porosity， % ****0 ****5 ****5 air permeability，m3•cm/m2 •h•*0Pa 0.**0.8 **6 ***0 acid resistance， % ≥*8 ≥*8 ≥*6 alkali resistance， % ≥*5 ≥*5 ≥*0 Acute coldness/heat resistance，(△T)℃ **0 pressure strength， N/piece ********0 piled weight，kg/m3 ********0（according to the different variety and Specification）
