Introduction
XD active ceramic ball is another new reactor supporting packing developed by the Institute of our company. The product is made on the basis of the inert alumina ceramic ball, by introducing a small amount of transition metal oxides in it. Not only has it high temperature resistance and high mechanical strength characteristics of the inert alumina ceramic ball, playing a role of filtering, gas-liquid separation and covering and supporting of the catalysts, but also it has a certain catalytic activity, i.e., in such processes of olefin hydrogenation, sulfur removal, nitrogen removal and benzene hydrogenation, when the active ceramic balls are packed at the top of the catalyst bed of the reactor, the mono-olefins and diolefins in the secondary processing crude oil can be primarily hydrogenated, reducing coking on the catalysts; and when they are packed in the bottom of the catalyst bed, the mercaptan produced from some reactions may be removed. Therefore, XD active ceramic balls can not only effectively improve the space utilization ratio of the reactors, but also they can protect the catalyst from being poisoned or being sintered to a certain degree, thus prolonging the service life of the catalyst.

application
XD active ceramic ball is an X-ρ type activated Al2O3 desiccant in the form of white spheres with strong water adsorption ability. Under certain operation and regeneration conditions, its drying depth can reach a dew point temperature below -70℃, and it is a micro-water depth drying desiccant. It is widely used in petrochemical industry for gas and liquid phase drying, the textile industry, the oxygen production industry, drying with an automated instrument air dryer, in PSA of air separation industry and so on. Due to its high net heat of monomolecular adsorption layer, therefore, it is highly suitable for use in heatless regeneration units.
