Briefly describe the effect of CO on the carbon dioxide hydrogenation reaction in the ethylene compression unit. The adsorption capacity of the carbon dioxide hydrogenation catalyst for various components in the pyrolysis gas is as follows: H2S > C2H2 > CO > C2H4. It can be seen that an excessive amount of CO in the pyrolysis gas occupies the adsorption sites intended for C2H2, thereby affecting the catalyst’s activity. Therefore, as the CO concentration increases during operation, it is necessary to raise the temperature at the reactor inlet accordingly. However, in the initial stage of catalyst use, when its activity is high, a certain amount of CO can actually improve selectivity. Everyone is welcome to discuss knowledge related to ethylene; let’s learn together and make progress together! ************************************* 1. What is HaiChuan Freelancer?
