Embodiment Construction

[0150] The present invention uses the back-mixed flow expanded bed hydrogenation reactor system of hydrocarbon-containing gas-liquid upper feed distributor, and is characterized in that comprising the following steps:

[0151] (1) In the first hydrogenation reaction process AR, in the presence of hydrogen, liquid phase hydrocarbons and solid particles, the first raw material AR1F containing at least carbon and hydrogen elements enters the first hydrogenation reaction process AR for a first stage The hydrogenation reaction ARR obtains a hydrogenation reaction product BASE-ARP, discharges a hydrogenation reaction effluent ARP-X, and discharges a hydrogenation reaction process net product ARP;

[0152] The first raw material AR1F, including the liquid raw material AR1FL and the possible solid particle raw material AR1FS;

[0153] In the first stage of hydrogenation reaction process AR, hydrogen gas, liquid phase hydrocarbons and solid particles may exist at the same time;

Abstract

The invention provides a backmixing-flow expanded-bed hydrogenation reactor system with a distributor for a hydrocarbon-containing gas-liquid upper feed. The backmixing-flow expanded-bed hydrogenationreactor system is used for processing the hydrocarbon-containing gas-liquid upper feed AR1P-M and hydrogen-containing gas lower feed BR1FH and can also be used for processing hydrocarbon-containing liquid lower feed BR1D-L; the inner upper space of a backmixing-flow expanded-bed hydrogenation reactor BRXE is provided with a liquid collecting cup and a liquid eduction tube; the upper space of theliquid collecting cup is divided into an upper feed distribution zone KD1 and a liquid removing zone KD2 for an interior product BRXE-8P of the reactor BRXE; the KD1 is located above the KD2, and a guiding and flow-gathering ring is used for separating the KD1 and the KD2; liquid flowing out from the guiding and flow-gathering ring GFC is mixed with the product BRXE-8P; and then the obtained mixture falls down into a liquid collecting zone of the liquid collecting cup for liquid removal and separation. With such a structure, the system can eliminate gas gathering zones, prevent mutual interference and stabilize flow fields.

Description

technical field [0001] The back-mixed flow expanded bed hydrogenation reactor system with hydrocarbon-containing gas-liquid upper feed distributor is used to process hydrocarbon-containing gas-liquid upper feed AR1P-M and hydrogen-containing gas-liquid lower feed BR1FH, and the hydrocarbon-containing liquid lower feed can also be processed at the same time BR1D-L, the upper space in the back-mixed flow expanded bed hydrogenation reactor BRXE is provided with a liquid collection cup and a liquid outlet pipe, and the space above the liquid collection cup is divided into the upper feed distribution area KD1 and the internal product BRXE-8P of the reactor BRXE. The liquid area KD2 and KD1 are located above KD2 and separated by the guide flow collector. The liquid flowing out of the guide flow collector GFC is mixed with the product BRXE-8P and then falls to the liquid collection area of ​​the liquid collection cup for deliquid separation. The structure It has the functions of elim...
