摘要
以制备合成气为目标,采用自供热鼓泡床对木屑进行提高H/C的富氧.水蒸气定向气化实验。分析当量比(ER)、水蒸气配比(S/B)、富氧浓度(OC)变化时对产气各组分及H2/CO(H/C)的影响。结果表明:相同O2浓度和水蒸气配比条件下,当量比在一定范围内越高,H/C越高;产气H/C主要受水蒸气配比和O2浓度的影响;自供热鼓泡床富氧-水蒸气气化工艺中,制备合成气最佳工艺条件:O2浓度为60%-70%、当量比为0.33.0.38、水蒸气配比约为0.56,对应最佳H/C为1.13。
Considering synthesis gas preparation as the target, the experiment on the gasification of sawdust with steamoxygen enriched air is carried out in a bubbling fluidized bed with the directional target of improving the H/C. The effect of air equivalence ratio (ER), steam to biomass ratio ( S/B ) and oxygen H2/CO (H/C)were investigated. Results showed that under the condition concentration ( OC ) on the gas compositions and of same OC and S/B, the higher the ER within a certain range, the wider the experiment of S/B affordable range is, the higherthe target parameter H/C are ; The H/C is mainly affected by S/B and OC ; In theself-heating bubbling bed with steam-oxygen enriched air gasification process, the optimum process conditions for synthesis gas is : OC in the range of 60%-70%, ER in the range of 0.33-0.35, S/B is about 0.56, thecorresponding optimum H/C is 1.13.
