Lignocellulosic biomass gasification is considered as one of the effective methods for transforming scattered biomass into heat, power and various chemicals. As a fundamental step for biomass gasification, pyrolysis has remarkable influence on products distribution and char reactivity during the further step. Further research on the pyrolysis process of lignocellulosic biomass is beneficial to optimize and promote the process of gasification. In this paper, pyrolysis characteristic of a kind of lignocellulosic biomass model compound (cellulose) was explored through thermogravimetric analyzer. The temperature was from 25 °C to 950 °C under various heating rates (10, 20, 40 °C·min-1) with nitrogen atmosphere. A three step selecting method for mechanism function was used to check out the optimum model from fifteen kinds of most frequently used mechanisms. The results indicated that under various heating rates, the optimum mechanism model for the cellulose in this paper was different. The values of activation energy and frequency factor for cellulose pyrolysis calculated by the three step method in this paper under 10, 20, 40 °C·min-1 were 245.95, 212.09 and 144.27 kJ·mol-1, 8.47E+17, 5.35E+18 and 1.20E+11 s-1, respectively.

The purpose of this study is to investigate the catalytic effects of different metals in Shengli lignite on the char reactivity. The pyrolysis of Shengli lignite and various metal catalyst loaded coal was investigated in a small fixed-bed reactor, and the gasification activity with steam for different chars was compared as well. The results show that Fe, Ni, Ca and K could effectively lowering the gasification temperature, enhancing the gasification reactivity of SL char. Alkali (K) and alkaline earth (Ca) could be feasibly used as catalysis for the catalytic steam gasification at relatively low temperatures (550~700°C) to produce gases with high H2 (63.2~63.8 v%) and low CO (below 0.9%), and promoting the carbon-water reaction, the water-gas shift reaction to some extent.
