Title:
METHOD FOR PRODUCING RESOURCES FROM SEAWEED
Document Type and Number:
WIPO Patent Application WO/2024/048722
Kind Code:
A1
Abstract:
Developed is a process for using an organic material to produce liquid hydrocarbons and carbides. Provided is a method for producing industrial resources from seaweed, said method comprising: a first step for, after using seaweed to perform a low-temperature hydrothermal treatment at 120-250°C, performing solid-liquid separation to obtain a first liquid and a first solid residue that has an O/C ratio of 0.3-0.8; and a second step for, after using a first aqueous phase that has been obtained from the first liquid obtained in the first step to perform a high-temperature hydrothermal treatment at 250-370°C, performing solid-liquid separation to obtain a second solid residue and a second liquid that contains a heavy oil component-containing liquid.
