摘要： A process for preparing a zeolite containing catalyst which has improved attrition resistance, and causes improved octane with no appreciable change in dry gas and coke make when used during catalytic cracking processes is disclosed. The catalyst is prepared by modifying the zeolite with a phosphate containing solution. The zeolite preferably includes an REY large pore zeolite. Treatment of the zeolite is best accomplished in an aqueous solution, at a pH range from about 2 to about 6, containing a water soluble phosphate compound. The phosphate treatment of the zeolite is carried out by deagglomerating the zeolite in an aqueous mixture in the presence of an aqueous phosphate containing solution, such as an aqueous solution of ammonium monohydrogen phosphate. The aqueous mixture containing phosphate modified zeolite is then combined with matrix precursors to form a slurry. The slurry is preferably spray dried to form the catalyst having a diameter less than 200 microns. The novel catalyst is used in the catalytic cracking of hydrocarbons in an FCC, moving bed or other catalytic cracking apparatus. The catalyst can be used for treating resids in which the hydrocarbon feedstock has a higher average molecular weight, a lower API gravity and/or a higher metals content than gas oil.
摘要翻译：公开了一种制备含有催化剂的沸石的方法，其具有改善的耐磨性，并且在催化裂化过程中使用时，引起干燥气体和焦炭产生明显变化的改进的辛烷。通过用含磷酸盐溶液改性沸石制备催化剂。沸石优选包括REY大孔沸石。沸石的处理最好在含有水溶性磷酸盐化合物的约2至约6的pH范围的水溶液中完成。沸石的磷酸盐处理通过在含磷酸盐水溶液如磷酸一氢铵的水溶液的存在下，在含水混合物中使沸石分解进行。然后将含磷酸盐改性沸石的含水混合物与基质前体合并形成浆料。浆料优选喷雾干燥以形成直径小于200微米的催化剂。新型催化剂用于FCC，移动床或其他催化裂化装置中烃的催化裂化。催化剂可用于处理其中烃原料具有比瓦斯油更高的平均分子量，较低的API比重和/或更高的金属含量的残渣。

摘要： A method for continuous monitoring the presence of entrained catalyst in a regenerator flue gas stream of a fluidized catalytic cracking unit is provided. The method has the following steps: (a) passing the regenerator gas stream through a separation system to remove a portion of the catalyst fines and to create a cleaner regenerator gas stream; (b) collecting a sample portion of the cleaner regenerator gas stream and directing the sample portion of the cleaner regenerator gas stream through an inertial separating device to separate entrained catalyst from the sample portion of the cleaner regenerator gas stream; (c) collecting any separated catalyst from the inertial separating device; and (d) monitoring the efficiency of the separation system by analyzing at least the amount of the collected separated catalyst or the particle size of the collected separated catalyst. An apparatus for measuring the amount of potentially erosive catalyst fines in a regenerator flue gas stream in a fluidized catalytic cracking unit is also provided. The apparatus is a sampling probe for collecting a sample portion of the regenerator flue gas from a line through which the regenerator flue gas stream flows, and an inertial separating device located downstream of the sampling probe and in fluid communication therewith, for removing any entrained catalyst fines from the sample portion of the regenerator flue gas.

摘要： A cyclone and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added around a clean gas outlet tube in a cyclone body. Solids and some gas are withdrawn via a solids outlet and discharged into a catch chamber. Some of the gas discharged with the solids into the catch chamber is returned to the interior of the cyclone body via an opening in the cyclone. Chaotic reflux of gas back into the cyclone via the solids outlet is eliminated. The device may be used as an FCC regenerator third stage separator or to improve other gas/solid separations.
