摘要： A conversion apparatus for catalytic cracking a hydrocarbon feed to light hydrocarbon comprises at least one riser reactor, a dense bed reactor, a disengager, and a stripper. A dense bed reactor which is separated from disengage, is employed to enforce further cracking hydrocarbon to light olefins, with low methane yield. Moreover, the spent catalysts discharged from the outlet of the dense bed reactor can be introduced into the stripper via a specific catalyst transporting channel, to maintain catalyst concentration in the dense bed reactor that can be advantageous to deeper cracking of the intermediate products to produce more light olefins, particularly propylene.

摘要： A catalytic conversion process for increasing the light olefin yields, which comprises bringing a hydrocarbon oil feedstock into contact with a catalytic conversion catalyst in a catalytic conversion reactor including one or more reaction zones to carry out the reaction, wherein the hydrocarbon oil feedstock is subjected to the catalytic conversion reaction in the presence of an inhibitor; and separating the reactant vapor optionally containing the inhibitor from the coke deposited catalyst, wherein a target product containing ethylene and propylene is obtained by separating the reactant vapor, and the coke deposited catalyst is stripped and regenerated for recycle use by being returned to the reactor. The process can weaken the further converting reaction of produced light olefins such as ethylene and propylene to 50-70% of the original level by injecting the inhibitor; thereby it can increase the yields of the target products. When vacuum gas oil is used as the feedstock, the yield of ethylene is as high as 8.73 wt % and that of propylene is as high as 29.30 wt %, increasing by 14.4% and 26.6% respectively comparing to those obtained without the inhibitor being injected.

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。
