Introduction 

Inert alumina ceramic balls are widely used in petroleum, chemical industry, chemical fertilizer, natural gas, environmental protection and other industries, as the covering support materials and tower packing of catalyst in the reactor. It has the characteristics of high temperature and pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature change in the production process. Its main function is to increase gas or liquid distribution point, support and protect the active catalyst with low strength.

产品介绍

     概述

      惰化铝填料球广泛用于石油、化工、化肥、天然气及环保等行业,作为反应器内催化剂的覆盖支撑材料和塔填料。它具有耐高温高压,吸水率低,化学性能稳定的特点。能经受酸、碱及其他有机溶剂的腐蚀,并能经受生产过程中出现的温度变化。其主要作用是增加气体或液体分布点,支撑和保护强度不高的活性催化剂。
