Isothermal differential characteristics of gas–solid reaction in micro-fluidized bed reactor

Pyrolysis behavior and kinetic study of phenol as tar model compound in micro fluidized bed reactor

“…It was defined by the produced gas volume against the total gas volume at the end of the reaction [19], which can be calculated through:…”

“…However, the main disadvantage is that the sample needs to be feed into the reaction chamber at normal temperature and there is a small mass-lose before reaching the preset temperature. Besides, due to the limitation of structure and design principle, TGA could not be carried out under the condition of high gas velocity [19,20]. To address this deficiency brought by TGA, Institute of Process Engineering in Chinese Academy of Sciences, Shandong University and Shandong Baichuan Tongchuang Energy Company developed the micro fluidized bed reactor (MFBR).…”

Characterization of coal char gasification with steam in a micro-fluidized bed reaction analyzer

“…Recently, a new micro-fluidized bed (MFB) reactor, with both its inner diameter and particle bed height about 20 mm, has been used to test gas-solid reaction characteristics and reaction kinetics [14]. The developed micro-fluidized bed reaction analyzer (MFBRA) integrates the advantages of quick heat and mass transfers in the MFB reactor, pulse feeding of micrograms of reactant sample by electromagnetic pulse method, and fast detection of reacted gas using a process mass spectrometer.…”

Fast co-pyrolysis of biomass and lignite in a micro fluidized bed reactor analyzer

“…However, synergetic effect was rarely observed in temperature programming way as a result of the different pyrolysis temperature ranges of biomass and coal. Furthermore, since the reaction temperature is determined by the reaction time and heating rate, it is impossible to separate the reaction temperature and reaction time when studying the co-pyrolysis kinetics via nonisothermal kinetic method, leading to complexity in kinetic calculation and great uncertainty in quantification (Yu et al, 2013a). Therefore, the results thus obtained are unsuitable to describe the reaction mechanism.…”
