A, product features and uses
LYZ-915/ LYZ-916 catalyst is a group of oil gas steam model conversion catalyst, it is suitable for reforming device to oil gas or natural gas as raw materials forindustrial steam hydrogen, ammonia synthesis gas, methanol synthesis gas,metallurgical reducing gas, can be applied to modern energy saving type AMV orBraum low ratio of water to carbon conversion of synthesis gas process ammonia.The LYZ-915 is arranged on the reformer tube is arranged on the upper, LYZ-916reformer tube lower part two, according to a certain proportion loading.

Four considerations, the normal operation of
Normal operating condition of catalyst
Temperature: T entrance: ≥ 450 ℃, export: T ≤ 900 ℃
Pressure: ≤ 4Mpa
H2O/C:3~8
The maximum allowable carbon space velocity: 2000h-1
Five, packaging, transportation and storage of catalyst
Catalyst for hard cardboard packaging, lined with plastic bag (or according to userrequirements packaging). The catalyst should pay attention to moisture, avoidrolling in the process of transportation, collision, intense shock, should rainfacilities. The catalyst should be stored in dry and ventilated warehouse, to preventcontamination and moisture.
