논문 초록 (Abstract)
Lignin pyrolysis has a significant opportunity of producing commodityphenolic chemicals from natural biomass resources or industrial byproducts. Bio-oil production of lignin pyroly sis in a fixed-bed system was systematically characterized by respo nse surface methodology (RSM) to optimize operating variables such as temperature, heating rate, and loadingmass. According to the mathemat ical model of RSM, the predicted maximum bio-oil yield of 30.1% and the actual bio-oil yield of 29.3% were obtained under the optimum co ndition: 669 degrees C temperature, 15 degrees C/min heating rate, and 6.97 g loading mass. Temperature significantly influenced both t he yield and the chemical composition of lignin bio-oils becausepyrol ytic decomposition of lignin consisted of temperature-dependen t stepwise reactions. The bio-oil under the optimum condition produc ed not only the higher yield but also the higher content (43.2%) of t he primary product (i.e., 2-methoxyphenol). (C) 2016 Elsevier B.V.
