Title:
REACTION PROCESS UTILIZING CRITICAL WATER
Document Type and Number:
WIPO Patent Application WO/2010/092909
Kind Code:
A1
Abstract:
The issue is to suppress the problems associated with by-products in order to allow an organic synthesis process effected through the action of supercritical water and an acid to progress stably. Provided are a method and a device whereby water is supplied to high-pressure pumps (110, 210) from water headers (101, 201), and a pressure reduction valve (324) is adjusted to give 35 MPA. The temperatures of preheaters (120, 220) and a heater (310) are raised so that the reaction temperature reaches 400°C. A reaction solution obtained by supplying an organic compound starting material (glycerin) from a starting material header (203') and an acid (sulfuric acid) from an acid header (203) and allowing the substances to act with supercritical water is cooled to 100-200°C through a first cooling (420). Solid components in the reaction solution are separated and removed from the reaction solution using a filter (320). After the reaction solution is cooled to a temperature of approximately 100°C or lower through a second cooling (620), the pressure is reduced (324), a third cooling (720) is additionally applied, and a synthesized final product (acrolein) is removed.
