摘要： A catalytic conversion process can convert inferior feedstock to high quality fuel oil and propylene. A inferior feedstock is introduced into first and second reactor zone, wherein the feedstock carry out first step and second step reactions by contacting with catalytic conversion catalyst. Product vapors separate from spent catalyst by gas-solid separation. The spent catalyst is stripped, regenerated by burning off coke and then returns to reactor. The product vapors are introduced into separation system to obtain propylene, gasoline, diesel, fluid catalytic cracking gas oil (FGO) and other products. The FGO is introduced into hydrotreating unit and/or extraction unit to obtain hydrotreated FGO and/or extracted FGO. Said hyrotreated FGO and/or extracted FGO return to the first reactor zone and/or another catalytic cracking unit to obtain propylene and gasoline. The extracted oil of said FGO is rich in double ring aromatics which are good chemical materials. The raffinate of said FGO is rich in chain alkane and cycloalkane which are suitable for catalytic cracking. More particularly, the invention relates to a process to utilize petroleum oil resources efficiently for decreasing the yield of dry gas and coke significantly.

摘要翻译： 催化转化过程可以将劣质原料转化为高质量的燃料油和丙烯。 将劣质原料引入第一和第二反应器区，其中原料通过与催化转化催化剂接触进行第一步和第二步反应。 产物蒸气通过气 - 固分离与废催化剂分离。 废弃的催化剂被汽提，通过燃烧焦炭再生，然后返回反应器。 将产品蒸气引入分离系统中，得到丙烯，汽油，柴油，流化催化裂化瓦斯油（FGO）等产品。 将FGO引入加氢处理单元和/或提取单元以获得加氢处理的FGO和/或提取的FGO。 所述经处理的FGO和/或提取的FGO返回到第一反应器区和/或另一个催化裂化装置以获得丙烯和汽油。 所述FGO的提取油富含双环芳族化合物，其为良好的化学物质。 所述FGO的萃余液富含链烷烃和环烷烃，适用于催化裂化。 更具体地说，本发明涉及一种利用石油资源有效降低干燥气体和焦炭产率的方法。
