摘要

以羧甲基纤维素钠(CMC)/华亭烟煤的超临界水共气化制氢为例

考察了温度(350～700 ℃)、压力(20～35 MPa)和物料(CMC+煤)的质量分数w(1.1%～2.0%)等对生物质/煤共气化气体产物的影响.模拟和实验结果表明:得到的主要气体产物是H

、CO

和CH

产气中H

的摩尔分数随温度的升高而升高

但温度升高到一定值后

的摩尔分数(x(H

)=67%)保持不变; 随物料质量分数的增加

的摩尔分数减小

物料的温度和质量分数的变化对产气的作用远大于压力; 制氢的适宜温度为450～550 ℃、压力为25 MPa左右、w≥15%.提出后续实验应着重提高物料在反应器内的加热速率

筛选研究在较低温度下能有效催化产氢的Ni催化剂.

Abstract

Crboxymethylcellulose(CMC)/Huating bituminous coal was considered to be an example of biomass/coal

and the effects of the reaction temperature(350-700 ℃)

pressure(20-35 MPa)and concentration of solution(1.1%-2.0%)on gaseous products during CMC/coal co-gasification in supercritical water were investigated. The simulation results and experimental data show that the main gaseous products are H

and CH

. Moreover

hydrogen mole fraction increases with the reaction temperature but it is constant(67%)at a high temperature. Hydrogen mole fraction decreases with the concentration

and temperature and concentration have larger effec

ts on gaseous products than pressure. In addition the reasonable parameters for hydrogen production during CMC/coal co-gasification in supercritical water are 450-550 ℃

25 MPa

and the solution concentration≥ 15%. It is suggested that heating rate of feedstock in the reactor should be increased and Ni catalyst with good effects at low temperature should be studied in the future experiment.
