(Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) 1. Exothermic reaction ； The decrease in bromine value and sulfur content releases a certain amount of reaction heat; as a result, there is a significant temperature rise in the hydrogenation reactor bed. 2. Hydrogen is consumed. 3. The volume decreases ； The total volume of the products after the hydrogenation reaction is less than the total volume before the reaction. Therefore, high pressure is favorable for the reaction. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Third Phase of HaiChuan’s Outstanding Management Members Selection Contest http://bbs.hcbbs.com/thread-1655902-1-1.html (Source: HaiChuan Chemical Forum)
