Title:
RARE EARTH AUXILIARY AGENT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/051150
Kind Code:
A1
Abstract:
Provided are a rare earth auxiliary agent and a method for preparing a rare earth auxiliary agent for producing clean energy or high-value chemicals, so as to realize the resourceful application of low-rank coal and biomass. The rare earth auxiliary agent consists of a rare earth chloride, a mixed rare earth chloride and a rare earth nitrate, and can be used as an auxiliary agent for carrying out a biochemical reaction between a microorganism and a substance to be converted, thereby enhancing the activity of the microorganism in the biochemical reaction, and promoting the conversion of low-rank coal (peat, lignite, low-metamorphic bituminous coal, weathered coal and coal gangue) and biomass into clean energy, namely, high-value chemicals such as biological methane, biological hydrogen or biological ethanol and fulvic acid, water-soluble humic acid, benzoic acid, benzaldehyde, and benzyl alcohol to achieve the carbon reduction conversion of high-carbon resources such as low-rank coal and biomass.
