Second-stage Reforming Catalyst (Model Z204/Z205)
〖Product Usage〗
Further thoroughly transform the residual methane in the first reformed gas (generally, the outlet methane value is required to be less than 0.5%), and adjust the appropriate hydrogen-nitrogen ratio for synthesis.
〖Features〗
The catalyst is a new type two-stage conversion catalyst adopted by Chengdu Shengli Technology Co., Ltd. with magnesium aluminum spinel as a carrier. It has:
- Good thermal shock resistance
- Strict impurity control;
- ?Better air distribution guidance
