石化企业培训资料。反再系统(大庆二重催车间主任任课哦)（Petrochemical enterprise training materials. Reverse system (Daqing, double reminders, workshop director, classroom oh)） Huazipiaoling artesian water, a kind of Acacia, two xianchou. First come, first served., xiangyanghua wood for spring. One year spent similar, each year is different. The piece should only be the sky, earth several times that. Thirty thousand in the East Sea, five thousand Ren Yue ferris. 1 what is the main function of the reactor? Answer: it is the space needed for the sufficient contact between the raw oil and the catalyst, and control the temperature and conversion rate to achieve the desired product distribution. What is the main function of the 2 regenerator? Answer: it provides catalyst regeneration and coke burning sites, uses the main wind (or oxygen) to burn the catalysts carbon deposition, restores the activity and selectivity of the catalyst, and uses the high efficiency cyclone separator to realize the separation of the gas from the catalyst. 3 what is the main function of the main air separator? Answer: the main air is distributed evenly along the entire bed section, providing a good initial fluidization condition. 4 what are the main functions of the riser separator? Answer: rapid separation of FCC gas from cracking catalyst to reduce harmful two reactions. What is the main function of the 5 settler? Answer: it provides separation sites for cracked oil gas and catalyst. What is the main function of the 6 stripping section? A: the right amount of superheated steam is injected into the catalyst, and the catalyst is contacted with the gas stripping steam to displace the oil and gas between the pores of the catalyst and the particles. The yield of the target product can be increased and the reaction anxiety can be reduced. 7 what is a catalyst? Answer: a chemical that affects the rate of reaction, but does not consume itself in the result of chemical reactions, nor does it change the substance that reflects th
