【Daily Question】 April 29, 2016 – Hydrogenation section: Multiple-choice question. Increasing the space velocity of the unit has an effect on the hydrogenation denitration reaction ( ). A. Unfavorable B. Little impact C. Favorable D. Uncertain A. Promotion of petrochemical activities: Notice regarding the large-scale event “I’m saving energy; where are you?” in the petrochemical area. http://bbs.hcbbs.com/thread-1579199-1-1.html This event offers awards in both written and photographic categories. When there are over 200 entries, an additional grand prize will be awarded; the value of this prize is 600 Haichuan coins. If there are more than 300 entries, the grand prize value increases to 1,000 Haichuan coins, and if there are 500 entries, it rises to 1,500 Haichuan coins. First prize: 3 Haichuan commemorative water cups. Second prize: 5 winners, each receiving 120 Haichuan coins. Honorable mentions: several winners, each receiving 200 wealth points. There’s a surprise waiting for those who reply to this post – money will be given away! http://bbs.hcbbs.com/thread-1580356-1-1.html
A: It is unfavorable. With the reaction temperature and hydrogen partial pressure remaining constant, increasing the space velocity reduces the contact time between the reactants and the catalyst, which is detrimental to the hydrogenation reaction
Increasing the space velocity of the device affects the hydrodenitration reaction (A). A. Unfavorable B. Little impact C. Favorable D. Uncertain
