Sulfurization method of process gas in the 65kg Dehsgasification process using shift catalyst
Thread Content
I would like to ask for the detailed steps for sulfiding the shift catalyst using process gas in the 65kg Texaco gasification process Fittings include whether an electric furnace is used, and precautions when the process gas is introduced, etc

The temperature increase of nitrogen is controlled by a nitrogen electric heating furnace. Control the temperature for vulcanization properly – it is necessary to regulate both the rate of temperature increase and ensure that the bed reaches the final vulcanization temperature. 2. During heating vulcanization, carbon disulfide can be added to the system only when the temperature at the upper part of the bed rises to 200°C. Since carbon disulfide undergoes a hydrogenolysis reaction at 200°C, releasing a large amount of reaction heat, it is necessary to control the amount of carbon disulfide added in order to prevent the temperature of the catalyst bed from rising excessively and causing the catalyst to be damaged. The initial addition amount should be small, with gradual increases thereafter; at the same time, the addition of carbon disulfide should not be accompanied by an increase in temperature, and no carbon disulfide should be added when the temperature is increased.
