Abstract

The improved fluidized bed reactor includes cylindrical reactor casing perpendicular to ground and phase separator in the upper part of the casing. The casing has material inlet in the bottom and product outlet on the upper side, and the phase separator consists of two, one inner and one outer, concentric cylinders of different inner diameters as well as the inner wall of the casing, with the inner cylinder having a lower top-less conic opening. The reactor is suitable mainly for the chemical reaction between different liquid and gas matters under the contact with solid particles, and has the advantages of great catalyst holding amount, high reactor utilization, simple structure, easy operation, etc.

Description

1. Technical field

[0001] The present invention relates to an improved ebullating bed reactor. The reactor is mainly suitable for chemical reactions of different kinds of liquid and gas substances in contact with solid particles. 2. Background technology

[0002] The ebullating bed hydrocracking process is recognized as a high conversion process. In this process, the catalyst can be replaced under the condition of non-stop, and the continuous operation can be completed. Moreover, the raw material oil has a wide application range and a high conversion rate. US.pat.No.RE 25,770 describes a typical ebullating bed process: the hydrocarbon liquid enters the reactor from the lower part of the reactor after being mixed with hydrogen, moves upward through the fluid distribution plate and passes through the catalyst bed. The catalyst moves randomly with the rising gas-liquid mixture. The expansion degree of the catalyst bed is controlled by the reaction feed and the circulating li...
