Title:
SEPARATION DEVICE AND METHOD FOR CATALYST AND HEAVY HYDROCARBON IN SLURRY BED REACTOR
Document Type and Number:
WIPO Patent Application WO/2017/181814
Kind Code:
A1
Abstract:
A separation device for a catalyst and heavy hydrocarbon in a slurry bed reactor. The separation device comprises a filter tank (1), a sieve plate (2), an electromagnet (3) and a filtrate tank (4). A catalyst outlet of the filter tank (1) is connected to an input end of the filtrate tank (4). An output end of the filtrate tank (4) is connected to a filtrate circulation return inlet of the filter tank (1). A pipeline between the output end of the filtrate tank (4) and the filtrate circulation return inlet of the filter tank (1) is communication with a product conveying pipe of a product storage tank (5). The catalyst outlet of the filter tank (1) is further connected to a catalyst discharging pipe. A lower portion inside the filter tank (1) is provided with the sieve plate (2), on which a magnetic filter medium layer (6) is provided. The filter tank (1) is provided with the electromagnet (3), which generates a uniform magnetic field at the sieve plate (2). The separation device provides highly efficient solid-liquid separation without blocking a filter medium, and a separated solid catalyst can be recycled and reused, enabling a slurry bed reactor to operate continuously in industrial applications.
