A Study of Cellulose Pyrolysis chemistry and Global kinetics at high Heating Rates

摘要

Cellulose pyrolysis has been studied in a laminar entrained flow reactor (LEFR). As described in the previous companion paper, the reactor is capable of high heating rates (-10~4 K/s) and has been characterized in detail to ensure that pyrolysis of lignocellulosic materials occurs under kinetic control at the conditions of the reactor. The extent of cellulose pyrolysis in the LEFR was monitored by sampling the gas phase products with a molecular beams mass spectrometr system, and independently by sampling and weighin residues on a filter paper.
