**4. Experimental study of PEFB gasification in a protoype-scale downdraft gasifier**

After it is proven that pelleitzed PEFB has a high potential to be used as fuel for producer gas production via gasification process in the previous section, this section aims to conduct the feasibility of using pelletized PEFB as fuel for power generation via gasification process.

#### **4.1 Feedstock and feedstock preparation**

Feedstock used for the experiments in a prototype scale gasifier is pelletized PEFB which was prepared by the same method as described in section 3.1. The proximate and ultimate analyses of feedstock as well as other physical properties have already been shown in Table 7 and Table 8, respectively.
