This compilation presents the main results reported in literature regarding the application of the fluidised bed reactor in the fermentative production of hydrogen using different synthetic and complex substrates, such as: glucose, sucrose, xylose, sugarcane vinasse, cheese whey, cassava wastewater and glycerin. Additionally, the results of studies on the dry torrefaction process of various types of fluidised bed biomass in an inert gas medium are presented, as well as the results of studies on torrefaction in a fluidized bed in a gas medium, which produces a mixture of inert gas and oxygen. Using a fluidized bed reactor for activated carbon production, the effect of various process parameters such as particle size, fluidizing velocity, process time, static bed height, activation temperature and fluidizing medium are studied. The authors propose that the development and implementation of the suspended bed reactor is the most reasonable means to achieve promising catalytic hydrogenation.
