Abstract

In this study, the pyrolysis of Zichang˚Coal (ZC) was investigated by thermogravimetry (TG) using three˚Catalysts, and the yields of the products obtained from pyrolysis, as well as gas˚Composition, were investigated by gas˚Chromatography (GC) using a fixed-bed reactor. The˚Catalytic mechanism was discussed from the kinetic analysis and gas˚Composition. The˚Coats??"Redfern integral approach was employed for investigating the reaction kinetics of the˚Coal??"catalyst mixture. The general effect of the additive on the pyrolysis reactivity of˚Coal was˚Compared by DTG analysis and TG. The results indicated that KCl,˚CaO, and Fe2O3 exhibit a˚Catalytic effect on the pyrolysis of ZC. With the addition of˚Catalysts, gas production and˚Char productivity increased, while the tar yield first increased and then decreased.˚Coal pyrolysis˚Can be divided into two areas: With the addition of activation energy, pre-exponential factor and˚Catalysts decreased. Experiments were˚Conducted with three˚Catalysts, and the˚Catalyst reactivities for the pyrolysis of˚Coal followed the order of KCl >˚CaO > Fe2O3.
