Problems solved by technology

Therefore, if a perforated plate is installed, the rise of the air bubbles is hindered by the resistance of the perforated plate, and at the same time, the rise rate of the slurry accompanying the rise of the bubbles is reduced, and the rise rate of the slurry cannot be obtained sufficiently.

Abstract

Bubble tower type hydrocarbon synthesis reactor (100) comprising reactor main frame (110) accommodating slurry (120) having solid catalyst particles (124) suspended in liquid hydrocarbon (122), and distributor (140) disposed at an inferior portion of the reactor main frame (110) and used to feed a synthetic gas composed mainly of hydrogen and carbon monoxide into the slurry (120), wherein the reactor main frame (110) in its interior is provided with baffle plate (150) so as to block the side-wall side of the reactor main frame (110) and open the center part thereof.

Description

technical field [0001] The present invention relates to a bubble column type hydrocarbon synthesis reactor, in particular to a reactor for Fischer-Tropsch synthesis reaction by blowing synthesis gas into a slurry obtained by suspending solid catalyst particles in liquid hydrocarbon. [0002] This application claims priority from Japanese Patent Application No. 2006-95020 filed on March 30, 2006, the contents of which are incorporated herein by reference. Background technique [0003] As one of the reaction systems for the Fischer-Tropsch synthesis reaction (hereinafter referred to as "FT reaction") to produce hydrocarbons and water from synthesis gas mainly composed of hydrogen and carbon monoxide, there is Catalyst particles are suspended in a slurry in liquid hydrocarbons to perform FT reactions in a bubble column-type suspended bed (also known as a slurry bed) FT reaction system. In addition, hydrocarbons synthesized by the FT reaction are mainly used as raw materials fo...
