Seeking to use an increasingly clean and sustainable
energy matrix, the use of biomass derivatives becomes an increasingly present
alternative. Among the processes that can be used to generate higher added
value products from biomass, the gasification process is highlighted. The
irregular and spherical shape of the biomass particles inserted in the bed make
this process difficult, however, and it is necessary to add an inert material
(usually sand), forming a polydisperse bed filled with a binary mixture, but the biomass/sand is extremely important
for the fluidization process to occur. Therefore, the present work had the
objective of determining the fluidization curves of a binary mixture of sand
and fodder turnip, which is formed by 10%, 30%, 50%, 70% and 90% of biomass in
its volume. The fluidization of the Raphanus
sativus L. husk fluidized up to a 70% biomass ratio in the blend,
increasing the yield of the system and providing a viable and sustainable
alternative for the application of biomass in biorefinery processes.
