57.低温接触ガス化技術を用いた家畜排泄物からのエネルギー製造

抄録

We carried out low temperature catalytic-gasification of feces of domestic animals which were beef cattle, dairy cattle, swine and chicken. Gasification experiments using two-stage fixed-bed reactor in argon and steam flow were performed. One gram of each samples were bedded at upper stage, and catalyst (Ni/Al_2O_3) or non-catalyst (river sands) were at lower stage. The temperature of lower stage was kept at 923K, and the upper stage was raised from room temperature to 1123K at 10K/min. The producing gases throwing impinger were sampled and analyzed with GC. The yield of the total gas including hydrogen producing from the feces was remarkable increased by our catalytic-gasification method.
