  • 대마에 대한 분석 결과, 인피 섬유의 경우 리그닌 함량은 7.6%로 다른 목질계 바이오매스나 일년생 초본류와 비교하여 매우 낮은 리그닌 함량을 나타냈으며 탄수화물 함량은 65.4%로 목질계 바이오매스와 유사하고, 초본류보다는 오히려 높았다. 목부는 리그닌 및 탄수화물 함량이 활엽수와 유사한 경향을 나타내었는데 특히 높은 자일란의 함량이 확인되었다. 또한 회분 함량이 인피섬유와 목부에서 각각 5.0%와 2.3%로 낮은 값을 나타내어 당화 및 발효 공정에 적용될 때 회분에 의한 공정 장애(스케일링 등)의 가능성을 낮추어 줄 것으로 사료되었다. 최종적으로 이러한 화학적 분석을 통해 대체에너지 생산을 위한 자원으로서 대마의 가능성을 확인할 수 있었다.

Enhancing Enzymatic Saccharification by Aqueous Ammonia Soaking Pretreatment on Several annual plants (일년생 바이오매스(옥수수 줄기, 담배 줄기, 대마 목부)의 암모니아 침지 전처리가 효소 당화에 미치는 영향)

  • Effects of aqueous ammonia soaking to three annual plants (hemp woody core, tobacco stalk and corn stover) awere investigated to focus on the enzymatic saccharification characteristics change by this treatment. At two different levels of treatment ($90^{\circ}C$-16 h and $45^{\circ}C$-6 days), higher temperature treatment led to more enzymatic saccharification of cellulose to glucose by commercial cellulase mixtures (Celluclast 1.5L and Novozym 342 from Novozyme Korea). Difference among annual plants were significant. corn stover was the best response to enzymatic saccharification of cellulose and xylan by comercial enzymes all treatment conditions but tobacco stalk was the worst response to all of them. chemical composition or physical structure difference may brought this difference.

  • We made densified wood pellet by hemp woody core as replacing wood resource. Hemp was separated into the bast fiber and the woody core by hot steaming treatment. The hemp woody core had a similar lignin content and carbohydrate composition with hardwood. Also, the hemp had a low ash content, which resulted in a low ash formation in pellet burning. Heating value of the hemp pellet had a very similar to the pellet made by hardwoods. The hemp woody core can replace hardwood for densified wood pelletmaking.

  • Autohydrolysis at different temperature levels was applied as industrial hemp pretreatment technique for glucose generation. Main structural components removed by autohydrolysis was xylan, which is more sensitive in acidic hydrolysis condition than cellulose or lignin. Higher temperature reaction conditions promoted more biomass components (xylan) removal than lower temperature, which led to better respond to enzymatic saccharification of residual biomass after autohydrolysis. With $185^{\circ}C$ and 60 min, saccharification degree was 53.0% of cellulose in hemp woody core biomass.

  • We prepared densified wood pellet by agricultural waste. The hemp woody core was used as replacing wood resource. Hemp was separated into the bast fiber and the woody core by hot steaming treatment. The hemp woody core had a similar lignin content(19.4%) and carbohydrate composition with hardwood(20-25% lignin in hardwood), respectively. Also, the hemp had a low ash content(0.5%), which resulted in a low ash formation in pellet burning. Heating value of the hemp pellet(18.40 MJ/kg) had a very similar to the pellet made by hardwoods. The hemp woody core could be replaced the hardwood for densified wood pellet.
