Embodiment 1
[0031] A method for preparing biomass fuel with fresh cow dung as the main raw material, the specific steps are:
[0032] 1) Raw material pretreatment: crush the discarded mushroom sticks, dry them naturally to make the moisture content below 10wt%, and prepare the mushroom sticks; heat the discarded shells at a heating rate of 15°C / min Calcining at 900°C for 5 hours to obtain calcined shell powder;
[0033] 2) Fermentation: Mix 80wt% of fresh cow dung, 15wt% of mushroom sticks and 5wt% of calcined shell powder to make a mixture; The moisture content of the material is reduced to 25wt%; the nitrogen fixation-desulfurization composite microorganism is composed of Pseudomonas putida ( Pesudomonas putida ), Pseudomonas flavinogenes ( Cellulomonas flavigena ), Aspergillus oryzae ( Aspergillus oryzae ), Bacillus licheniformis ( Bacillus licheniformis ) and Streptomyces griseus ( Streptomyces griseus ) is compounded according to the mass ratio of 3:5:2:1:6, and the amount...
Embodiment 2
[0041] A method for preparing biomass fuel with fresh cow dung as the main raw material, the specific steps are:
[0042] 1) Raw material pretreatment: crush the discarded mushroom sticks, dry them naturally to make the moisture content below 10wt%, and prepare the mushroom sticks; heat the discarded shells at a heating rate of 30°C / min Calcining at 1100°C for 3 hours to obtain calcined shell powder;
[0043] 2) Fermentation: Mix 80wt% of fresh cow dung, 17wt% of mushroom sticks and 3wt% of calcined shell powder to make a mixture; The moisture content of the material is reduced to 20wt%; the nitrogen fixation-desulfurization composite microorganism is composed of Pseudomonas putida ( Pesudomonas putida ), Pseudomonas flavinogenes ( Cellulomonas flavigena ), Aspergillus oryzae ( Aspergillus oryzae ), Bacillus licheniformis ( Bacillus licheniformis ) and Streptomyces griseus ( Streptomyces griseus ) is compounded according to the mass ratio of 3:5:2:1:6, and the amoun...
Embodiment 3
[0051] A method for preparing biomass fuel with fresh cow dung as the main raw material, the specific steps are:
[0052] 1) Raw material pretreatment: crush the discarded mushroom sticks, dry them naturally to make the moisture content below 10wt%, and prepare mushroom sticks; heat the discarded shells at a heating rate of 20°C / min Calcining at 1000°C for 4 hours to obtain calcined shell powder;
[0053] 2) Fermentation: Mix 80wt% of fresh cow dung, 16wt% of mushroom sticks and 4wt% of calcined shell powder to make a mixture; The moisture content of the material is reduced to 25wt%; the nitrogen fixation-desulfurization composite microorganism is composed of Pseudomonas putida ( Pesudomonas putida ), Pseudomonas flavinogenes ( Cellulomonas flavigena ), Aspergillus oryzae ( Aspergillus oryzae ), Bacillus licheniformis ( Bacillus licheniformis ) and Streptomyces griseus ( Streptomyces griseus ) is compounded according to the mass ratio of 3:5:2:1:6, and the amount of...
