METHOD FOR PREPARING BIOOIL FROM BIOMASS USING ACIDIC NANOPOROUS SOLID CATALYST

摘要

The present invention relates to a preparation method of biooil from biomass using an acidic solid catalyst having nanopores. More particularly, the present invention relates to a method for effectively preparing biooil with a high carbon content using an acidic solid catalyst having nanopores. The biooil with a high carbon content has a low oxygen content, and is prepared from a waste chili stem and a waste garlic stem including a high lignin content. The biooil is prepared by thermal decomposition of biomass containing at least 25 wt% of lignin in the presence of a silicate-based acidic solid catalyst.
