| 中文摘要 |
| 为了掌握废轮胎在流化床内的气化特性,利用自行设计的小型流化床试验装置系统,对废轮胎在不同的过量空气系数下在400～700℃温度范围内进行了空气气化实验.分析了废轮胎气化效率、固定碳转化率、气化气热值、产气量以及气化气成分随气化温度、过量空气系数的变化规律.结果表明,废轮胎气化的最佳运行条件为气化初始温度700℃,过量空气系数α=0.4.在此条件下得到的气化气成分主要包括CH4、CO、H2、C2H6和高分子有机化合物,此时的气化效率为47.96%,气化气低位热值为4 804kJ/m3. |
| 英文摘要 |
| A laboratory-scale fluidized-bed gasifier was designed and used to investigate the characteristics of waste tires gasification.Granulated tires were gasified with different excessive air ratios at a temperature range of 400～700℃.The gasification efficiency,carbon conversion efficiency,heating value,yield and components of syngas were analyzed.Results showed that the optimum operation conditions were achieved when the gasification temperature was 700℃ and the excessive air radio(EAR) was 0.4.A gaseous product,mainly containing CH4,CO,H2,C2H6,and longer-chain hydrocarbon with a lower heating value(LHV) of about(4 804)kJ/m3,can be generated at the highest gasification efficiency of 47.96% under the optimum operation conditions. |
