A novel technique has been developed to successively collect the fines, produced by the atrition of catalyst particles in aqueous suspension, as samples representing the outer shells of the particles. With this technique, a number of commercial equilibrium FCC catalysts were investigated. The experimental results show that in the process of residcrackitig,the intraparticle and interparticle distributions of coke on catalysts forresidual cracking are not uniform due to the presence and the coking reaction of unvaporized resids. However, for gas oil FCC, as a result of prevailing .vapor-phase reaction, the distributions, of, coke on catalysts are uniform both in intraparticle and interparticle. Additional information was derived from the analysis of contamination metal contents of samples taken primarily for coke content determination. The radial distributions of nickel on catalysts for both VGO and residual cracking are uniform.

本文建立了测定流化催化裂化(FCC)催化剂上的焦炭以及污染金属沿径向分布的一种新方法——研磨法。用这种方法考察了多种工业待生剂,取得了确定的结果,并从理论上初步探讨了提升管反应器中的传递过程和生焦反应。研究结果表明,由于液相组份的存在和反应,渣油裂化催化剂粒内和粒间的焦炭分布都是不均匀的,而汽相反应的瓦斯油裂化催化剂粒内和粒间的焦炭分布都是均匀的。污染金属镍在这两种类型的催化剂上的径向分布也都是均匀的。

The dependency of the instantaneous CO2/CO during regeneration on carbon content, oxygen concentration, regeneration temperature and the type of catalyst was investigated. The change of CO2/CO value with temperature was given for several types of cracking catalyst. The intrinstic CO2/CO value was also calculated. The data of carbon burn-off kinetics thus obtained could be as reliable as the data of...

本文提出了测定流化催化裂化(FCC)催化剂再生过程中的CO_2/CO值的一种新方法。利用双热导池同时连续检测再生烟气中CO_2和CO的瞬时浓度,得到了CO_2/CO值与含碳量、氧浓度(5.63%~21.65%)、催化剂类型及温度(600~720℃)的相互关系。并且利用已测得的裂化催化剂存在下CO的氧化数据,对密相床出口处CO_2/CO值进行了扣除计算,得到了本征的CO_2/CO,并同Arthur的结果进行了比较。在测定CO_2/CO值的同时,还测得了一批消碳动力学数据,与前人的工作进行了比较,证明了该实验数据的可靠性。
