Each feedstock was pulverized to a sieve size ranging from 0.5 to 1.0 mm because each feedstoc with a smaller particle size was difficult to be steadily supplied. The proximate (accepted basis) and ultimate (dry ash-free basis, d.a.f) analyses of each feedstock were performed using a Rigaku Thermo Plus 2 thermogravimetric differential thermal analyzer (TG-DTA) and a Thermo Quest EA 1110 automatic elemental analyzer, respectively.In addition, the higher heating values (HHV, dry basis (d.b.)) of each feedstock were analyzed using an IKA C 2000 basic calorimeter system.
