- Abstract
- Lignin pyrolysis has a significant opportunity of producing commodityphenolic chemicals from natural biomass resources or industrial byproducts. Bio-oil production of lignin pyrolysis in a fixed-bed system was systematically characterized by response surface methodology (RSM) to optimize operating variables such as temperature, heating rate, and loading mass. According to the mathematical 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 condition: 669 degrees C temperature, 15 degrees C/min heating rate, and 6.97 g loading mass. Temperature significantly influenced both the yield and the chemical composition of lignin bio-oils because pyrolytic decomposition of lignin consisted of temperature-dependent stepwise reactions. The bio-oil under the optimum condition produced not only the higher yield but also the higher content (43.2%) of the primary product (i.e., 2-methoxyphenol). (C) 2016 Elsevier B.V.
