Experimental study on mesophilic biogas fermentation of tobacco leaf residues

The experiment adopted the batch anaerobic digestion process to produce biogas using tobacco leaf residues as raw materials at 30 degrees C. The results indicate that the net biogas production of the experimental group during total fermentation time of 30d is 2275mL and the TS, VS gas production rate, gas production rate of raw material and tank volume gas production rate respectively is 100 mL/g, 204 mL/g, 63 mL/g and 0.2 mU/mL.d.
