Description
1. Inert Alumina Ceramic Ball
It's broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc. There are lots of merits for it, for instance, the stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties, and so on. It is capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.
2. Activated Alumina Ceramic Ball
It's another novel supporting packing of reactor. There are excellent properties for active ceramic ball such as the heat resistance, mechanical strength, filtration or dispersion of gas or liquid, and covering or supporting of catalyst, etc. In addition, there is well property of catalytic activity, which can play the role of catalyst promoter in many processes (olefin hydrogenation, desulfurization, and denitrification, etc. ). During the processes of hydrofining, hydrocracking, reforming pre-hydrogenation, and benzene hydrogenation for oil cut fractions, if Active Alumiona Ceramic Ball is loaded above the catalyst layer in the reactor, it can induce the mono-olefins or dienes to hydrogenate initially in the secondary operation of crude oil. In contrast, if Active Alumiona Ceramic Ball is loaded in the bottom of catalyst layer, it can also remove the mercaptan, which is produced within some reactions. Therefore, it can not only improve the space usage ratio, but also on some extent to protect catalyst from poisoning or agglutinating with active ceramic ball, and it can prolong the lifetime of catalyst utilization.
