摘　　要：(接第9期第5页) 3工艺操作条件的影响 除选好催化剂外,如何用好催化剂也是十分关键的.用好催化剂主要是调控和优化操作条件.操作条件的优化可以更好地体现"量体裁衣"所设想的效果.装置有几个影响产品收率的变量可由操作人员来调控,包括反应温度、原料预热温度、再生温度(取热器操作条件)、反应压力、进料流率、进料雾化分散条件、催化剂补充率(卸剂量、平衡催化剂活性及其金属含量),以及分馏塔操作条件和回炼油量,等等.从以下一些例子可以看出操作条件的影响是很大的.The profitability of a refinery is related to the performance of FCC unit and the profitability of FCC u-nit is on intimate terms with catalyst selection and application. Catalyst selection has the direct relation with feedstock property, status of FCC unit and the product slate desired. Good profitability cannot be directly generated from the proper selection of catalyst, and it needs a proper operation as well. Optimizing operation conditions based on catalyst property is the crucial factor to obtain profit. Catalyst selection and application are the responsibility of refinery, and catalyst vender only provides assistance.
