Ceramic Balls (also known as support ball, inert ball and catalyst support media) were very important component in the catalytic process in the refinery, gas processing and petrochemical industry. Its main function is to act as packing material and at the same time to support the catalyst bed in order to prevent breakthrough or loss of catalyst or adsorbent materials downstream of the reactor vessels due to the high pressure and temperature inside the reactor vessels during the operation. Ceramic ball come up with a few different sizes, which are 1/8″, 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1¼”, 1½”, 2″. The size was arranged layer by layer at the top and bottom of the vessel, with different sizes of ceramic ball.
High Alumina Ball 99% is equal Denstone 99 Support Media. It is in chemical composition99+% alpha alumina and a maximum 0.2wt% SiO2 . Because of its high alumina content and low silica (SiO2 ), it’s a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
99% High Alumina Ball has very excellent thermal properties, with its high density high-temperature resistance 1550℃, also it’s a good choice for heat retention or equilibration media.
For its superior chemical resistance, it’s suitable for applications in olefin processes, such as ethylene dryers, where there’s the polymerization problem.
