一、二段转化催化剂粗苯加氢催化剂一、二段转化催化剂针对甲烷蒸汽重整制取CO、H_2等合成气而开发的PT-C1-段转化催化剂,PT-C2二段转化催化剂和PT-C3热保护催化剂,适用于焦炉气、天然气等制甲醇、合成氨的工艺该催化剂的特点是:1、耐高温,强度高,不易结焦或积碳,不含能转移的杂质;2、采用多孔双头弧面圆柱结构,催化剂的外表面积更大,可在更高的空速下运行;3、多通道结构使得气流在催化剂颗粒间的分布更均匀,气
The first and second conversion catalyst crude benzene hydrogenation catalyst The first and second conversion catalyst Aiming at the steam reforming of methane to produce synthesis gas such as CO and H_2, the PT-C1-stage conversion catalyst, PT-C2 second-stage conversion catalyst and PT -C3 thermal protection catalyst suitable for coke oven gas, natural gas and other methanol, ammonia synthesis process The catalyst is characterized by: 1, high temperature, high strength, not easy to coke or carbon deposition, can not transfer impurities; 2, using Porous double-headed arc cylindrical structure, the catalyst surface area larger, can be run at higher space velocities; 3, multi-channel structure makes the gas flow in the catalyst particles more evenly distributed between the gas
