“…일본잎갈나무는 용재수종으로서의 가치가 높고, 소나무 다음으로 공급량이 많은 수종이다. 내수성과 내구성이 뛰어나고 제재목 가격이 비교적 저렴하여 건축재, 선박, 생목, 합판 농업 용구, 펄프, 펠릿으로 많이 사용되고 있다 (Kim et al, 2015;Lee et al, 2018;National Institute of Forest Science, 2019). 펠릿의 경우 일본잎갈나무를 원료로 사용한다면 지속적인 공급이 가능한 대표수종이기도 하다 (Kang et al, 2018;Yang et al, 2018aYang et al, , 2018b.…”

“…Larix kaempferi has a high value as a commercial purpose and is the second largest supply following pine tree. It has excellent water resistance and durability, and the price of lumber is relatively cheap, so it is widely used for building materials, ships, raw wood, plywood agricultural tools, pulp, and pellets (Kim et al, 2015;Lee et al, 2018;National Institute of Forest Science, 2019). In the case of pellets, Larix kaempferi is also a representative tree species that can be continuously supplied if it is used as a raw material for them (Kang et al, 2018;Yang et al, 2018aYang et al, , 2018b.…”

This study was conducted to suggest the optimal periods for planting and felling Larix kaempferi tree by monitoring its cambial activity period. In addition, the heat summation to induce the cambial activity of Larix kaempferi was investigated. The study sites were at Mt. Worak and Mt. Midong. After selecting 5 trees at Mt. Worak and Mt. Midong, the cambium samples were collected using a mini trephor with 2 mm diameter from April 7 to October 6, 2017 at Mt. Worak, and from April 7 to September 29, 2017 at Mt. Midong. After the collected cambium samples were embedded in PEG2000, transverse thin sections with a thickness of 10 to 15 µm were prepared using a microtome. One Larix kaempferi sample from each site, Mt. Worak and Mt. Midong, in which the accurate monitoring of cambial activity was impossible due to the formation of traumatic resin canal, was excluded from the study. The observation of the initiation date of cambial activity under a light microscopy revealed that 2 specimens from Mt. Worak and 3 from Mt. Midong showed the initiation on April 28. The remaining 2 specimens of Mt. Worak and 1 specimen of Mt. Midong were initiated on May 4, which was a week later than the others. The heat summation that induced the initiation of cambial activity was 196.4-271.8 at Mt. Worak and 204.7-277.3 at Mt. Midong, which was similar. The termination of cambial activity occurred between August 4 and 25 at Mt. Worak, and between August 4 and September 1 at Mt. Midong. Based on the above results, it was found that the optimal planting period for Larix kaempferi in Mt. Worak and Mt. Midong was before April, about a month before the cambium activity, and the felling period was from October when the cambial activity was completely terminated.

“…In this regard, there are reports in Korea that cite data that are not fully verified, which causes controversy (Kim, 2017). This is because studies on wood pellets in Korea focus mainly on fuel characteristics (Kim et al, 2015) or boiler combustion performance, but there is little information on substances emitted from wood pellet combustion. Some existing wood combustion systems bring about incomplete combustion due to combustion under inappropriate conditions, and therefore, CO, HC and soot are generated.…”

“…Yellow poplar is a major planting species due to its fast growth and high capacity for carbon absorption, so it has widely been planted in South Korea for bioenergy production [38]. As a result, potential of the wood species as a raw material for wood pellets production has been investigated by several researchers [8,9,31,37,[39][40][41][42][43][44]. This study thus aims at investigating the effect of reaction temperature on chemical composition, fuel properties and pelletability of torrefied LAR and YP.…”

Larch (LAR) and yellow poplar (YP) cubes were torrefied at 180, 220 and 260°C for 50 min to investigate the effect of torrefaction temperature on chemical composition, fuel properties and pelletability. When increasing the torrefaction temperature from 180 to 220°C, lignin content of torrefied LAR and YP increased from 28 to 34% and from 21 to 23%, respectively. Xylose contents of LAR and YP decreased to 11% at the torefaction temperature of 260°C. The thermal degradation of xylose by the torrefaction treatment has a significant impact on increasing the ash content, higher heating value and weight loss of the torrefied LAR and YP. When the lignin distribution of untreated and 180°C‐torrefied cubes were measured quantitatively by the microscopic analysis of SEM–EDX, the amount of lignin existing on the radial‐sectional areas of LAR and YP increased from 7.89 to 18.84% and from 6.37 to 17.71%, respectively. Durability of pellets fabricated with torrefied LAR and YP cubes decreased with the increase of torrefaction temperature. By the adjustment of a moisture content for the torrefied particles, durability of torrefied LAR pellets improved by 8–11% but that of YP decreased by 2–21%. Addition of 2 wt% starch, lignin and protein as a binder to 180°C‐ and 220°C‐torrefied LAR and YP affected the increase of pellets durability. Accordingly, it can be concluded that the addition of binder or moisture is needed to produce durable pellets made with torrefied LAR and YP while accounting for costs associated with the binders. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
