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 same format as this post. I. Requirements: 1. Only one question can be posted per day. The posting time is before 10 o’clock every day; if you see that no one has posted yet, go ahead and post right away. 2. The answers are set to hidden, with the responses 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, restore 300 wealth. 3. A corresponding amount of charm points can be obtained each month based on the number of posts; in other words, 30 posts earn 30 charm points as a reward. 4. For details, please refer to the special post in the Petrochemical section titled “One Question per Day” – the post dedicated to moderators who receive subsidies. The multiple-choice questions in its main text are as follows: The characteristics of paraffin-based crude oil include low density, high wax content, high freezing point, low sulfur and resin content, and it belongs to crude oil of ancient geological age. Reply +2 wealth (already set to automatic); correct answer +5 wealth. Explanations and sharing of work experience +10 wealth. Daily quiz bank: http://yunpan.cn/cF2uyHDDwTv94. Access password: e07c.

Paraffin-based crude oil is characterized by a low density, high wax content, a high freezing point, low sulfur and resin contents, and it belongs to crude oil of ancient geological age. Correct
Yes. Paraffin-based crude oils generally contain more than 50% alkanes. They are characterized by low density, a high wax content, a high freezing point, and low levels of sulfur and gum; they belong to crude oils that are geologically ancient.

Paraffin-based crude oil is characterized by a low density, high wax content, a high freezing point, low sulfur and resin contents, and it belongs to crude oil of ancient geological age. (Yes)
Paraffin-based crude oil is characterized by a low density, high wax content, a high freezing point, low sulfur and resin contents, and it belongs to crude oil of ancient geological age. Correct. Paraffin-based crude oils generally contain more than 50% alkanes. They are characterized by low density, high wax content, high freezing points, and low levels of sulfur and resin. These are crude oils of ancient geological origin, such as Daqing crude oil and Nanyang crude oil. Naphthenic crude oils are characterized by a high content of naphthenes and aromatics, high density, and low freezing points; they generally contain large amounts of sulfur, gums, and asphaltenes. These are crude oils that are geologically young, such as the Gudao crude oil and Liaohe crude oil. ? Intermediate base crude oils fall between the two, such as Shengli crude oil.
