Abstract :
When the heat catalytic methane sensors work in the circumstance with H2S, they will be poisoned and lose their activity and can not work well. The paper analyzed the hypostasis of the poisoning of the sensors. And the general methods of anti-H2S poisoning were discussed. The methods of anti-H2S poisoning were worked out by realistic experiments. That is, use pre-poisoning and aging to advance the anti-H2S poisoning ability of the sensor. And the electric field can make the result better.
