Embodiment approach 1
[0114] Biomass refers to the general term for the accumulation of a certain amount of animal and plant resources and wastes derived from them. However, fossil resources do not belong to biomass. As the biomass used in Embodiment 1, any biomass that is thermally decomposed to produce charred products such as agriculture, forestry, livestock, fishery, and waste can be used. It is preferable to use biomass with high effective calorific value, and it is preferable to use woody biomass.
[0115] Examples of woody biomass include the following.
[0116] ·Pulp black liquor, sawdust and other papermaking by-products, bark, sawdust and other wood processing by-products,
[0117] ・Forest residual materials such as branches, leaves, treetops, and short-sized materials,
[0118] · Cedar, cypress, pine and other harvested materials,
[0119] ・Materials from special forest products such as waste shiitake wood from edible fungi,
[0120] ·Forestry biomass such as fuelwood forest materia...
Embodiment 1
[0214] use with image 3 In the same equipment as shown, biomass was dry-distilled to conduct a test for producing biochar.
[0215] The comparison of the yield of the carbonized product 2 was performed between the case where the tar 4 was mixed with the hot air 5 and the case where the tar 4 was not mixed. As the raw material 1, a residue of a biomass system composed of empty fruit bunch (EFB) of oil palm produced in the process of producing palm oil was used. The water content of EFB was 30% by mass.
[0216] In the case of mixing the tar 4 with the hot air 5 (the example of the present invention), when the mass flow rate of the raw material 1 for drying the substrate is 1, the mass flow rate of the tar 4 mixed with the hot air 5 is 0.1. The blowing temperature of the hot air 5 was 930°C, and the carbonization temperature, that is, the temperature of the carbonized product immediately before cutting was 500°C. The temperature of the exhaust gas 3 discharged from the upper ...
Embodiment 2
[0220] use with Figure 4 In the same facility as shown, a test of producing biocoke by dry distillation of the same biomass as in Example 1 was carried out.
[0221] The comparison of the yield of carbonized product 2 was performed between the case where tar was mixed with the hot air 21 and the cold air 23 and the case where no tar was mixed.
[0222] In the case of mixing tars 22 and 24 in the hot air 21 and the cold air 23 (example of the present invention), when the mass flow rate of the raw material 1 for drying the substrate is 1, the mass flow rate of the tar 22 mixed in the hot air 21 is 0.1, Let the mass flow rate of the tar 24 mixed with the cold air 23 be 0.03. The blowing temperature of the hot air 21 was 990°C, and the carbonization temperature, that is, the temperature of the carbonized product immediately before cutting was 500°C. The temperature of the cold air 23 is 80°C. The temperature of the exhaust gas 3 discharged from the upper part of the packed bed...
