【Q&A Question 072】March 13, 2018: What is the impact of the amount of hydrogen mixed in during hydrogenation? A higher hydrogen mixing ratio helps stabilize the bed temperature, reduces catalyst coking, and promotes the hydrogenation reaction. A low hydrogen mixing ratio reduces the efficiency of the reaction and can lead to catalyst coking. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

A higher hydrogen mixing ratio contributes to stabilizing the temperature rise in the bed, reducing catalyst coking. However, a decrease in the hydrogen mixing ratio due to hydrogenation reactions leads to a decline in reaction efficiency, which may result in catalyst coking
Whether the amount of hydrogen mixed in is high or low, it will cause uneven flow of the feed oil within the furnace tubes, resulting in large fluctuations in the temperature at the furnace outlet. A low amount of hydrogen mixed in prevents the reaction heat from being carried away in a timely manner
A higher hydrogen mixing ratio helps stabilize the bed temperature, reduces catalyst coking, and facilitates the hydrogenation reaction； A low hydrogen mixing ratio reduces the efficiency of the reaction and can easily lead to catalyst coking.
A high hydrogen mixing ratio can increase the reaction depth and prevent catalyst coking, which is beneficial for protecting the catalyst, but it increases energy consumption
