To increase the popularity of this section, special daily quizzes on equipment, processes, and safety are held, with the motto: \"Knowledge is built through accumulation.\" I hope everyone will participate actively; by learning and making progress, they can also earn wealth. What are the four key points for heating and reducing a synthetic catalyst, and they will be explained. Answer: ① Three lows: namely low-temperature effluent ； Low-hydrogen reduction ； After reduction is complete, maintain a low-load operation period of 72 hours. ②Three stabilities: namely, stability in temperature elevation ； Hydrogen replenishment stabilization ； Stable water output. ③Three controls: namely, controlling the hydrogen replenishment rate ； Control the hourly water output ； Control the CO2 concentration. ④Three prohibitions: namely, raising the temperature and increasing hydrogen levels cannot be done simultaneously ； Moisture must not be brought into the tower ； Do not allow water to flow at high temperature for a long time. Participation: Replies 1-3 Wealth ； Correct answer: Reward of 5-10 wealth points ； Note: Questions for the day are valid only on that day; this post is valid for 24 hours.

1. Three lows: low-temperature water discharge, low-hydrogen reduction, and a 72-hour period of low-load operation after the reduction process is completed. 2. Three stabilities: stable temperature rise, stable hydrogen supplementation, and stable water output. 3. Three controls: controlling the hydrogen addition rate, controlling the hourly water output, and controlling the CO2 concentration. 4. Three prohibitions: raising the temperature and hydrogen level cannot be done simultaneously; moisture is not allowed to enter the tower; water discharge at high temperature for extended periods is prohibited.
That is, low-temperature outlet water； Low-hydrogen reduction ； After reduction is complete, maintain a low-load operation period of 72 hours. That is, to control the hydrogen replenishment rate ； Control the hourly water output ； Control the CO2 concentration. Three prohibitions: namely, temperature and hydrogen pressure cannot be increased simultaneously ； Moisture must not be brought into the tower ； The high-temperature water outlet time should not be too long.
