“…Due to the gas cooling when it is drifted upwards, some of the tar is condensed on the falling biomass while large amounts leave the gasifier with the producer gas. Thus, this type of gasifiers suffers from its high tar content that typically exceeds 100 g/Nm 3 which limits its usage for thermal applications rather than power production [59]. The producer gas is cooled down to approximately 200°C while passing through the drying zone, leading to significant enhancement in cold gas efficiency in comparison to other types of fixed-bed gasifiers [60]).…”

This article summarizes various biomass gasification methods and explains their advantages and disadvantages. First, theoretical aspects of gasification and the variety in reactor designs are overviewed. Despite the eminent effect of reactor design on gas product quality, gasification agents remain the dominant factor that determines the gas composition. Steam gasification is a thermochemical process that promotes organic carbonaceous substances into carbon monoxide and hydrogen while reducing the presence of dilutants. However, several obstacles during gasification and downstream processing have to be overcome to achieve adequate maturity. Gasification characteristics of steam were compared to the other gasification agents, including air, oxygen and CO2. The key performance parameters affecting steam gasification include raw material properties, additive and catalytic materials. While the key operating parameters include operating temperature, residence time, superficial velocity, equivalence ratio and steam-to-biomass ratio. Finally, the techno-economic evaluation and challenges facing the commercialization of steam gasification were discussed.

“…Tar formation is one of the major technical challenges of updraft gasification. Cerone et al found that the type of gasifying agent residence time and average reaction temperature affected the tar yield [56]. Specifically, the tar yield was 137 g/kg in air gasification and 163 g/kg in the air/steam gasification.…”

“…In the case of the reactor design, several studies analyzed how is the behavior of the BFB gasification process is and how the reactor design is affected by bed material [15][16][17], bed agglomeration [18][19][20][21][22], gasifying agent [9,10,[23][24][25][26], use of catalysts [20,27,28], hydrodynamics [2,29], biomass segregation [5,30], kind and size of biomass [25,[30][31][32][33][34][35], temperature conditions [32,36], or gasification process [37][38][39]. Results from the experimental test were also studied in [23,24,33,34,[40][41][42], and finally, other publications integrated models and tests to validate simulations [43,44]. In addition, some reviews compared researcher works carried out in the biomass gasification field [31,[45][46][47]…”

The methods currently used for designing a fluidized bed reactor in gasification plants do not meet an integrated methodology that optimizes all the different parameters for its sizing and operational regime. In the case of small-scale (several tens of kWs biomass gasifiers), this design is especially complex, and, for this reason, they have usually been built in a very heuristic trial and error way. In this paper, an integrated methodology tailoring all the different parameters for the design and sizing of a small-scale fluidized bed gasification plants is presented. Using this methodology, a 40 kWth biomass gasification reactor was designed, including the air distribution system. Based on this design, with several simplified assumptions, a reactor was built and commissioned. Results from the experimental tests using this gasifier are also presented in this paper. As a result, it can be said the prototype works properly, and it produces syngas able to produce thermal energy or even electricity.
