Wood Pyrolysis - an overview | ScienceDirect Topics
网页The products from pyrolysis process are classified into three categories: biochar, bio-oil, and gas. Various parameters such as particle size, reactor type, and reaction conditions of temperature, heating rate, residence time, gaseous medium (nitrogen, carbon dioxide and hydrogen), and feedstock type affect pyrolysis process.
Wood Pyrolysis - an overview | ScienceDirect Topics
网页Thermochemical processes. Pyrolysis: Wood that is subject to rapid thermal decomposition in the absence of oxygen is known as pyrolysis. This process produces bio-oil liquids, gases, and char. The wood is first comminuted and then delivered to a high-heat reactor with a temperature of around 932°F (500°C).
Lignin pyrolysis reactions - Journal of Wood Science
网页2017年1月17日 — Lignin, an aromatic constituent of woody biomass, is a potential renewable aromatic feedstock for a sustainable future carbon economy. Pyrolysis-based technologies, such as fast pyrolysis and gasification, are promising methods for converting lignin into biochemicals, biomaterials, and biofuels.
