详细研究了将建筑废弃木材和木质生物质中未回收的间伐木材作为冶金焦炭生产原料之一，添加到煤中进行炭化的技术。在碳化试验中，四种类型的木质生物质在物质平衡和碳化产物的组成方面显示出基本上几乎相同的结果。与原木相比，压缩成形为不小于10 mm的木质生物质允许添加率增加到1.5%，同时抑制焦炭强度的降低。在200-350°C下的热压缩成形（其中发生木质生物质的热解）抑制焦炭强度的降低，并且因此将允许木质生物质的使用的增加。结果，发现了通过添加压缩成形的木质生物质用作焦炭制造的原料的可能性。
The technology using waste wood from construction and thinned wood that are not recycled in the woody biomass as one of raw materials for producing metallurgical coke was examined in detail by adding them to coal and carbonizing them. In the carbonization tests, four types of woody biomasses showed substantially almost the same results in respect to material balance and composition of carbonized products. Compared with raw woods, woody biomasses compressively formed to not smaller than 10 mm permit an increase in the addition rate to 1.5% while inhibiting the lowering of coke strength. Hot compressive forming at 200–350°C where pyrolysis of woody biomass occurs inhibits the lowering of coke strength and will therefore permit an increase in the use of woody biomasses. As a result, the possibility to use as a raw material for the coke manufacturing by adding the compressively formed woody biomass was found.
