基于载热体供热的生物质气化反应特性原位研究
In situ study of biomass gasification reaction characteristics based on heat carrier heating
摘要
Abstract
This study used a high-temperature stage coupled with optical microscope system to investigate in situ the effect of the heat carrier on the apparent morphological changes of biomass particles during the heating process,and explored the influence of CO2 atmosphere and different temperatures of the heat carrier heating on the gasification reaction characteristics of biomass particles.The results indicate that during the heating process of biomass particles,the heat carrier has an inhibitory effect on the apparent morphological changes of biomass particles,and the temperature corresponding to the peak rate of area shrinkage change increases by about 50℃.In the process of biomass particles gasification,due to lignin pyrolysis,the gasification rate of biomass particles on the heat carrier shows a first fast and then slow trend at a temperature of 600～700℃,and then undergoes a brief period of rapid gasification before the gasification reaction ends.When the temperature reaches 750～850℃,the trend of area shrinkage rate of biomass particles gasification on the heat carrier is almost the same as that of biomass particles gasification without heat carrier.Under the heating condition of the heat carrier,biomass particles is less affected by graphitization and the reaction is more complete.关键词
