【Daily Question 2019】Hydrogen production and hydrogenation section – Question No. 047: Briefly explain why catalysts need to be regenerated Answer: Due to the long-term operation of the catalyst, carbon deposits gradually form on its surface, causing a decline in its activity. To restore this activity, air is introduced into the system under certain operating conditions in order to burn off the carbon deposits on the catalyst and restore its activity; hence, the catalyst needs to be regenerated. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Due to the long-term operation of the catalyst, coke and carbon deposits gradually form on its surface, causing a decline in its activity. To restore this activity, air is introduced into the system under certain operating conditions in order to burn off the coke on the catalyst and restore its activity; hence, the catalyst needs to be regenerated.
Due to the long-term operation of the catalyst, carbon deposition gradually forms on its surface, causing a decline in its activity. To restore this activity, air is introduced into the system under certain operating conditions in order to burn off the carbon deposits on the catalyst and restore its activity; therefore, the catalyst needs to be regenerated
The purpose of regeneration is to remove carbon deposits from the catalyst surface and restore its activity, thereby reducing production costs and improving economic efficiency.
Due to the long-term operation of the catalyst, carbon deposits gradually form on its surface, causing a decline in its activity. To restore this activity, it is necessary to introduce air into the system under certain operating conditions in order to burn off the carbon deposits on the catalyst and restore its activity; hence, the catalyst needs to be regenerated.
Under long-term operation conditions, coking and carbon deposition form on the surface of the catalyst, which leads to a decrease in its activity. To restore its hydrogenation activity, it is necessary to regenerate it.
After the device has been operating for a period of time, carbon deposits accumulate on the surface of the catalyst, affecting its catalytic activity. Catalyst regeneration involves burning off the carbon deposited on the catalyst’s surface in order to restore its activity
Due to the long-term operation of the catalyst, coke and carbon deposits gradually form on its surface, causing a decline in its activity. To restore this activity, air is introduced into the system under certain operating conditions in order to burn off the coke on the catalyst and restore its activity; hence, the catalyst needs to be regenerated.
