Description

Activated Ball With the support of Dalian Institute of Chemistry and Physics, a new kind of chemical packing, activated ball, was developed for catalyst support and coverage. It&#**9; s made by adding tiny transition metallic oxides in the inert alumina ball. Therefore, besides inert alumina ball&#**9;s characters of high mechanical strength, high chemical stability and heat endurance, activated ball can not only filter & distribute gas or liquid, cover & support catalyst in the reactor, but also remain certain catalytic activity. It can facilitate catalysis during various processes, ***** olefin hydrogenation, desulfurization, and denitrification. For some specific processes, ***** hydrogenation of distillate oil, hydrocracking, and benzene hydrogenation, if filled with activated ball on the top of catalyst bed in the hydrogenation reactor, it can support preliminarily olefin hydrogenation and prevent catalyst from caking. If filled activated ball at the bottom of catalyst bed, it can remove undesired mercaptan generated from some reaction processes. Applying activated ball, it can not only improve the reactor&#**9;s space application efficiency largely, but also prevent catalyst from poisoning or agglomeration, so as to lengthen its useful life. 　 　 Technical Specification Item Product type AB-I AB-II AB-III Appearance Light yellow Yellowish brown Mauve AL2O3, % ≥*0 ≥*0 ≥*0 Active composition Nio-Mo*3 Nio-W*3 CoO-Mo*3 Bulk density, g/ml 1.**1.4 1.**1.4 1.**1.4 Specific pore volume, ml/g 0.***0.*0 0.***0.*0 0.***0.*0 Thermal shocking, △T℃ **0 **0 **0 Compressive strength, N/piece *******0 depends on product size & specification
