Title:
METHOD FOR PREPARING 4-ETHYLPHENOL BY CATALYTIC PYROLYSIS OF BAGASSE WITH ACTIVATED CARBON
Document Type and Number:
WIPO Patent Application WO/2018/161280
Kind Code:
A1
Abstract:
The present invention pertains to the field of utilization of biomass energy, and in particular relates to a method for preparing 4-ethylphenol by catalytic pyrolysis of bagasse with activated carbon. The present invention uses bagasse as a raw material and activated carbon as a catalyst. The activated carbon is prepared from biomass using a steam activation method. The bagasse is mechanically mixed with the activated carbon and then catalytically pyrolyzed in a hydrogen atmosphere at 240-410°C, and a liquid product rich in 4-ethylphenol can be obtained after condensing the pyrolysis gas. The yield of 4-ethylphenol and its purity in the liquid product are both high. In addition, the method of the present invention uses bagasse having a wide range of sources as a raw material and inexpensive activated carbon as a catalyst, making it possible to significantly reduce the production costs of 4-ethylphenol.
