Characteristics of gas-solid micro fluidized beds for thermochemical reaction analysis

[Display omitted] •Micro fluidized beds are special microchemical reactors with distinguishable characteristics.•Micro fluidized beds are useful in characterizing thermochemical reactions.•Several standardized micro fluidized bed reaction analyzers are commercially available.•Micro fluidized beds are under continuous research and development for more broad applications. Fuel conversion and clean energy reaction systems involve a variety of catalytic and non-catalytic gas-solid thermochemical reactions. A good understanding of the correct reaction mechanism and kinetics, as well as the profiles of reaction products, is of great significance to the development, design, and operation of such reaction systems. The micro fluidized bed reaction analysis provides an efficient and reliable method to acquire this essential information with low capital and operating costs, low energy consumption and enhanced safety. This paper provides an overview of the system and its characteristics for the micro fluidized bed reaction analyzer that has been well proven to be a reliable new approach as well as an instrument for characterizing various gas-solid thermochemical reactions.
