NOVEL METAL CATALYST SUPPORED ON ACTIVATED CARBON AEROGEL BEARING ACID SITE, PREPARATION METHOD THEREOF AND DECOMPOSITION OF LIGNIN COMPOUND USING SAID CATALYST

摘要

PURPOSE: A noble metal catalyst dipped in an active carbon aerogel including an acid center, a manufacturing method thereof, and a lignin complex decomposition method using the catalyst are provided to produce an expensive aromatic complex like phenol and benzene with high yield by decomposing lignin complex under the low pressure. CONSTITUTION: A noble metal catalyst dipped in an active carbon aerogel including an acid center selectively decomposes carbon-oxygen bonding of lignin among wood composite biomass component and transforms into an aromatic compound. The chemical equation of noble metal catalyst is expressed as Metal/Active Carbon Aerogel-Sulfonic acid(M/ACA-SO3H). The noble metal catalyst is dipped with a palladium with the active carbon aerogel including the acid center of 5-30 weight% based on the sulfur content, rhodium, ruthenium, and one or more of platinum group of selected noble metal.
