Investigation on in/ex-situ coal char gasification kinetics in a micro fluidized bed reactor
摘要
Abstract
In-situ char and ex-situ char gasification characteristic was studied by using a newly developed micro fluidiz ed bed reaction anal yzer (MFBRA) and the reaction kinetics parameter s were obtained.The in-s itu char gasification proceedsu sing the same atmosphere, temperature and reactor in the gasification following the pyrolysis; the ex-situc har 1 ga sification is defin ed as coal pyrolysis in Ar atmospher e and then gasification at hot state in the same reac tor; and ex-situ char 2 gasif cati on reaction is defined as coal pyrolysis in Ar atmosphere and then gasification after thermal annealing.By analyzing the three kinds of char, it can be seen that in-situ char has the largest specific surface area, lowest graphitiza tion degree, and strongest sorpt ion ability for CO2 .U ndert he minimized limitat ions of heat and mass transfer, in-si tu char gasification has the highest reaction rate, and lo west rea ction energy.The study also proves ther eliability of MFBRA for in-situ char gasification reaction.关键词
