ad-946氨分解催化剂
ad-946 ammonia decomposition catalyst
1. 产品概述 product deion
ad-946氨分解催化剂是我公司与中科院大连化学物理研究所合作开发，代替德国g-117的新产品，具有高催化活性，热稳定性能好，强度高的特点和抗中毒和抗结焦性能。主要用于焦炉煤气的净化和回收装置中的氨分解炉、克劳斯炉内，将煤气中的氨、氰化氢等有毒气体分解成n2、h2、co2，有效解决环境污染。
ad-946 ammonia decomposition catalyst is cooperatively developed by our company and chemical physics research institute in dalian of chinese academy of sciences, for insteading of germany g-117. it is provided with the properties of great catalytic activity, high mechanical strength, and excellent thermal and coking resistance. it is used in the ammonia decomposing furnace to decompose the nh3 and hcn etc. into n2, h2 and co2, and so as to effectively purify the coke-oven gas for the sake of environmental protection and prevent the equipment from corrosion.
