Fig. 5 shows a typical behaviour of the temperature profile in the reactor during the experiments. As it is observed, there are an oscillation of the temperature value in all the bed section during all the experiments, with the exception of the temperature of the producer gas, where the temperature remain more stable. The main reason of this variation is biomass movement inside the reactor during the gasification process. The temperature of the producer gas remains in the range of 410e430 K, lower than the typical range
of 700e720 K reported for this type of reactor
