Abstract

The invention relates to an individual activating process for catalysts in converting furnaces of a CO (carbon oxide) sulfur-resistant converting device. The activating process is characterized in that: a heating vulcanization line is arranged at an inlet of each of the converting furnaces, and an emptying line is arranged at an outlet of each of the converting furnace, so that after the catalyst in each converting furnace is changed, the converting furnace can be separated from a system, and then, the converting furnace can be heated and vulcanized individually. In comparison with the prior art, the individual activating process for the catalysts in the converting furnaces of the CO sulfur-resistant converting device, disclosed by the invention, effectively improves production efficiency and reduces activation cost of the catalysts; in addition, a supplement position of a vulcanizer is arranged at an outlet of a heater, so that the vulcanizer can be guaranteed to be vaporized sufficiently to be mixed with nitrogen sufficiently and uniformly, and further, the activation effect is guaranteed.

Description

technical field

[0001] The invention relates to a process for individually activating catalysts in each shift furnace in a CO sulfur-resistant shift device matched with a SHELL pulverized coal gasification process. Background technique

[0002] The carbon monoxide and sulfur-tolerant conversion processes matched with the SHELL pulverized coal gasification process mainly include high water-gas ratio technology, low water-gas ratio technology, and low water-gas ratio combined with high water-gas ratio technology. Since the CO content in the crude gas produced by the SHELL pulverized coal gasification process is as high as 60%~65%, if the crude gas is used to produce synthetic ammonia, since the CO content at the outlet of the conversion device is required to be controlled at about 0.4%, no matter which conversion device is selected Generally, at least 4 converter furnaces are required.

[0003] The active components of the newly loaded carbon monoxide sulfur-tolerant shift ca...
