Let’s start with an advertisement; it’s short, only about 500 words. By registering as a VIP, you can skip the ads; oh, I’m kidding – you can skip them even without being a VIP. Read it carefully – there are prizes available; that’s true! We warmly invite enthusiastic members and moderators to host a daily question; there is no limit on the number of participants, and whoever volunteers will be responsible for posting it. The question bank is already available; the responses can be seen. Just post it in the style of this post. I. Requirements: 1. Only one question can be posted per day. The posting time is before 10 o’clock every day; if no one has posted yet, go ahead and post right away. 2. The answer is set to hidden, with the reply visible, to facilitate management and scoring by moderators. 3. For specific requirements, please refer to the special post in the Petrochemical section titled “One Question per Day” – the post dedicated to moderators who receive subsidies. 2. Benefits: 10 Wealth points + 1 Charm point as an immediate reward for each post published. 2. To receive the automatic reward for spending money, you can go to the link to get the subsidy. Subsidy = 1.5 times the amount spent. Scatter 200, gain 300 wealth. 3. A corresponding amount of charm points can be earned each month based on the number of posts; in other words, 30 posts earn 30 charm points as a reward. 4. For details, see the special post in the Petrochemical Section titled “One Question per Day” – where moderators who receive subsidies can find the multiple-choice questions: The key to hydrogen pre-refining catalysts lies in reducing nitrogen removal and aromatic saturation capabilities ( ). Answer: False. The database of “One Question per Day” is available at http://yunpan.cn/cF2uyHDDwTv94; the access password is e07c. Replies with +2 wealth points (automatically assigned); correct answers earn +5 wealth points. Explanations and sharing of work experience grant +10 wealth points. For promotional activities, participation earns +10 wealth points. In the [Petrochemical Section], there is also a post titled “Share Your Ideas Anytime”. In the [Petrochemical Forum], there are posts related to recent job-related matters. In the [Petroleum and Chemicals Section], you can show off your “SimSun” font skills
Wrong. The purpose of hydrorefining is to remove sulfur, nitrogen, oxygen heteroatoms, and metal impurities from oils, while also selectively hydrogenating and saturating olefins, dienes, aromatics, and polycyclic aromatics in order to improve the performance of these oils.
The key to hydrogen pre-refining catalysts is to reduce denitration and aromatic saturation capabilities (Wrong)
Error-------------------------------On the contrary, it is (an increase)
The key to catalysts lies in improving denitration and aromatic saturation capabilities; the original statement is incorrect.
