Relationship of total volatile fatty acid,gas production and feed nutrients in vitro

Effects of adding mixtures of saponins on rumen microbes and gas production in vitro

The paper introduces a method for calculating gas production from CBM vertical fracturing wells or horizontal wells by setting up a hydraulic model.

The results showed that 10% of solids concentration was superior to others and 6% of solids concentration was the minimum on total biogas production, biogas production velocity and COD removal.

The results showed that the biogas production with straws pretreated by the agent was 29.

5%NaOH solution,the biogas production of the later is 34% more than the former.

Temperature fluctuation affected average biogas yield significantly,and biogas couldn't be produced until the room temperature reached 18℃,so a conclusion was achieved that fermentation process could carried on success.

Effect of solid-liquid separation on biogas yield in anaerobic fermentation of pig dung wastewater was experimented under the constant temperature of 30℃.

Investigation on the effect of temperature and chemical pretreatment on anaerobic digestion efficiency and biogas yield of corn stalk was conducted.

Application of a neural network optimization combinatorial prediction model to oil-gas yield forecasting;
