Abstract:
1. A slurry bed loop reactor comprising a riser and at least one downcomer ( 3 ), wherein two ends of the riser are connected to two ends of each downcomer ( 3 ) respectively via line ( 16 ) and line ( 7 ); the riser comprises a reaction section ( 1 ) and a settling section ( 2 ) with an increased tube diameter disposed on the reaction section ( 1 ); a gas outlet ( 13 ) exists at the top of the settling section ( 2 ); each of the downcomers ( 3 ) is divided into a filtrate section ( 5 ) and a slurry section ( 6 ) by a filter medium ( 4 ), wherein the filtrate section ( 5 ) is connected to a liquid outlet ( 10 ), and two ends of the slurry section ( 6 ) are respectively connected to two ends of the riser, wherein the settling section ( wherein the distance between the upper edge of said baffle and the top of the settling section is 1/10- 9/10 of the total height of the settling section; wherein the section above the upper edge of the baffle in the settling section is a gas-liquid separation section, and the section below the upper edge of the settling section is divided into a turbulence section ( wherein said turbulence section ( wherein the downcomer is connected via line (
