| Abstract: | Sunflower plate, wheat straw and bean straw were used as substrats, batch fermentation was adopted to study their biogas potential and characteristics at medium and at high temperature. The results are as follows: the total production of biogas of sunflower plate, wheat straw and soybean straw at 30℃ are 14 605 ,22 317,29 006 mL respectively, the highest average production of biogas (per day)are 1 910 ,950 ,1 050 mL;the methane content are 67. 7% ,70. 7% ,80. 7% , respectively, the unit TS biogas yield are 137. 90 mL/g,207. 47 mL/g,268. 51 mL/g respectively. The results showed that sunflower plate,wheat straw and soybean straw have high biogas production potential. |
