松木焦CO2气氛催化气化特性研究
STUDY ON CATALYTIC GASIFICATION CHARACTERISTICS OF PINE CHAR WITH CO2
摘要
Abstract
Biomass char gasification with CO2 can produce high purity CO through the reaction of gasification agent CO2 with carbon in char. The effects of four transition metal catalysts (Ni, Ce, Fe and Cr) and four different gasification temperature on gasication of pine char were studied under 30% CO2 condition by using gravimetric analysis. And then the nth level reaction model was applied to calculate the kinetic parameters of catalytic gasification for pine char from 710℃ to 990 °C by ABSW differential method. The results indicated that with the increase of gasification temperature, the reaction time was obviously shortened. When the gasification temperature reached up to 850℃ , high reaction rate can be obtained. Moreover, the gasification reactivity of pine char with CO2 was significantly improved through the addition of four different transition metal catalysts. The order of catalytic activity from high to low was Ni, Ce, Fe and Cr. According to this study, it was found that the experimental data agreed better with the nth level reaction model at high temperature range.关键词
