| 英文摘要 | Gasification is one of the effective ways for high-value utilization of coal, biomass and other carbon-containing fuels. To investigate the reaction characteristics of tar during gasification, naphthalene was selected as the tar model compound and converted in a micro fluidized bed by using fluid catalytic cracking (FCC) catalyst and lignite coke as contact cracking carrier. The cracking kinetics of naphthalene in terms of CH4 and H2 generation were calculated by Friedman method and integral method respectively. The results show that both FCC catalyst and lignite coke had obvious catalytic effect on naphthalene. When lignite coke was used for naphthalene cracking, the overall reaction activation energy was lower than that of FCC catalyst. The catalytic cracking of naphthalene over FCC catalyst was close to three-dimensional diffusion (spherical symmetry) and nucleation and growth (n=2/3) models, while the three-dimensional diffusion (cylindrical symmetry) and contraction geometry (cylindrical symmetry) models had a good fitting degree for naphthalene cracking using lignite coke. 漏 2021, Editorial Board of CIESC Journal.
