Brief Introduction

The bases of normal catalyst of Carbon Monoxide is the mixture of Copper Oxide and Manganese Dioxide, this kind of normal catalyst have very good catalytic effect under NPT drying condition. But its disadvantage is that it is quite sensitive to the moisture, it will be quickly poisoned and disabled once the humidity exceed 45%, so it is suitable to use under the dry environment. When the concentration of Carbon Monoxide is low, the catalytic effect of normal catalyst of Carbon Monoxide is not so good than the precious metal catalyst of Carbon Monoxide.

Usage method

Generally speaking, it is hard to control the humidity to be lower than 45%, the drying agent must be added from the gas inlet if the normal catalyst is the option, for the moisture must be absorbed first of all and then the air is dry and the next the normal catalyst works, the Carbon Monoxide will be catalyzed to Carbon dioxide.

Besides, do not use the catalyst constantly in the actual operation, move it away when the density of Carbon Monoxide is allowed, that is in case the catalyst is poisoned, only when the density is higher than the allowed scope, the bed of material of catalyst shall be installed on the air cleaning equipments.

In the confined space, the electrochemistry sensor of Carbon Monoxide is easy to alarm, not because the density of Carbon Monoxide exceeds the safe range indeed, for the Nitrogen Oxygen mixture might make the sensor alarm falsely. To make sure the alarm is right, the infrared sensor will be an good option and the signal that the equipment is received will be much more accurate.
