Title:
APPARATUS FOR HOMOGENEOUS MIXING AND CONTINUOUS INJECTING OF LIGNIN AND SOLVENT, LIGNIN DECOMPOSITION SYSTEM USING SUPERCRITICAL FLUID COMPRISING THE SAME, AND OPERATING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/240306
Kind Code:
A1
Abstract:
The present invention provides an apparatus for feeding a raw material mixture to a liquefaction reactor, comprising: a raw material receiving unit for receiving a mixture of lignin and a solvent supplied as a raw material; a partition wall which can move while separating the raw material receiving unit from a fluid receiving unit; a cylinder including the fluid receiving unit capable of receiving a fluid that is capable of applying pressure to the partition wall; a stirring means, provided in the raw material receiving unit, for stirring the raw material; and a discharging unit, disposed in a portion of the raw material receiving unit, for discharging the raw material stirred by the stirring means. According to the present invention, a feeding apparatus for homogeneously mixing and continuously injecting the mixture of lignin and a solvent can mix a mixture homogeneously by means of a stirrer having horizontal or vertical blades, and maintain the mixture to be injected into a reaction unit at a post stage. In addition, it is possible to more effectively prevent separation between the lignin and a liquid by specifying a pipe in the discharging unit to a certain value. After the raw material and a fluid are separated by means of the partition wall, the fluid is injected into the top of the partition wall such that a pressure is applied to the mixture, thereby allowing the homogeneously mixed mixture to be continuously injected into the reaction unit for a post-stage process.
