Which one should be the main one? The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Measures to increase the depth of hydrogenation reaction during normal operation: ① Increase the reactor inlet temperature; ② Increase the reaction pressure; ③ Improve the purity of recycled hydrogen; ④ Reduce the space velocity; ⑤ Increase the hydrogen-to-oil ratio; ⑥ Replace with a highly active catalyst. Raising the reaction temperature is the main approach used. Scoring criteria: 2 Wealth points for incorrect responses; *incomplete* answers earn 3–8 points. 10 Wealth points are given for correct answers accompanied by detailed explanations; responses that are correct but lack sufficient details earn 15–20 Wealth points. Please score according to these criteria. 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 Petrochemical Sector – “Creative Ideas for Energy Saving” campaign (sponsors sought; highest returns ever) http://bbs.hcbbs.com/thread-1666758-1-1.html Sponsors are being sought for this campaign; those interested can contact the event organizer.

Increase the reaction temperature； Reduce air velocity ； The reaction temperature is the main factor
Measures to increase the depth of hydrogenation reaction during normal operation: increasing the reactor inlet temperature; raising the reaction pressure; improving the purity of recycled hydrogen; reducing the space velocity; increasing the hydrogen-to-oil ratio; and replacing with a highly active catalyst, among which increasing the reaction temperature is the primary method.
1. Increase temperature, 2. Increase pressure, 3. Improve hydrogen purity, 4. Reduce space velocity... With an emphasis on increasing temperature!
Measures to increase the depth of hydrogenation reaction during normal operation: ① Increase the reactor inlet temperature. ② Increase the reaction pressure. ③ Improve the purity of recycled hydrogen. ④ Reduce the space velocity. ⑤ Increase the hydrogen-to-oil ratio. ⑥ Replace with a highly active catalyst. Raising the reaction temperature is the main approach used.
