钠离子分散度对福建高变质无烟煤催化气化特性的影响
Effects of dispersion of sodium ions on catalytic Fujian anthracite gasification
摘要
Abstract
With sodium carbonate and sodium dodecyl benzene sulfonate used as the catalysts respectively, the steam gasification kinetic experiments of Fujian Jianxin and Chuanghong anthracites were conducted in an atmospheric thermal balance, and the effects of catalyst loading amount ( 0% ~15%) and gasification temperature ( 850 ~950 ℃) were examined.The experimental data were fitted by shrinking core model. Meanwhile, the kinetic parameters were obtained.The results show that both sodium carbonate and sodium dodecyl benzene sulfonate can significanlt y increase the gasification rate and er duce the activation energy of gasification reaction of the two anthracite samples.Because the loading process of ac talyst LAS can make the sodium ions being dispesr ed more evenly, even with low concentration of Na+, the carbon conversion can be imp roved significantly and the gasificationr eaction time is reduced to .The experime nts prove that it is a new way for the application and devle opment of LAS in catalytic ts eam gasificationo f Fujian anthar cti e.关键词
