Thermal Conversion of Sugarcane Bagasse Coupled with Vapor Phase Hydrotreatment over Nickel-Based Catalysts: A Comprehensive Characterization of Upgraded Products

In the present work, we compared chemical profile of organic compounds produced in non-catalytic pyrolysis sugarcane bagasse at 500 °C with those obtained by in-line catalytic upgrading vapor phase 350 °C. The influence over was evaluated testing two Ni-based catalysts employing an inert atmosphere (N2) and a reactive (H2) under atmospheric pressure yields liquid varying from 55 to 62%. Major changes were evidenced process H2 atmosphere, wherein higher degree deoxygenation identified due effect synergistic action between catalyst H2. fraction phase, called bio-oil, showed increase relative content alcohols phenolic GC/MS fingerprint after process, corroborating upon derived sugar carboxylic acids. Thus, thermal conversion bagasse, presence catalysts, promoted performance pyrolytic vapors, acting mainly through dehydration reactions. Therefore, adoption this can potentialize use waste biomass produce bio-oil species, which have wide range applications energy industrial sectors.
