Global agricultural practices emphasize the demand for environmentally friendly and sustainable production strategies. Therefore, this study investigated impact of processed red clay (PRC), an eco-friendly material derived from clay, a microbial fertilizer containing Lactobacillus fermentum (MFcL) on tomato growth, fruit quality levels, soil properties. Tomatoes were transplanted cultivated in open-field experiments. PRC, MFcL, PRC+MFcL treatments applied at 500 mL·plant-1 four times...
The non-isothermal and isothermal pyrolysis properties of H lignin P extracted from different biorefinery processes (such as supercritical water hydrolysis fast pyrolysis) were studied using thermogravimetry analysis (TGA) pyrolyzer-gas chromatography/mass spectrometry (Py-GC/MS). lignins characterized by ultimate/proximate analysis, FT-IR GPC. Based on the (TG) derivative (DTG) curves, thermal decomposition stages obtained products analyzed at each stage pyrolysis. was also carried out 400,...
Catalytic co-pyrolysis of particle board, a waste wood biomass, and polypropylene (PP), petroleum-based plastic, was carried out with mixing ratio 1:1 over representative mesoporous material, Al-MCM-41 catalyst. The Si/Al ratios the catalysts were controlled at 20 80 to investigate effect acidity characterization catalyst performed by X-ray diffraction, N2 adsorption-desorption, NH3 temperature-programmed desorption. catalytic pyrolysis board showed higher yield gas lower oil than...
Platinum catalysts impregnated on different nanoporous materials, Meso-MFI, Si-SBA-15 and AI-SBA-15, were synthesized, the hydroconversion of n-dodecane over these was performed. The catalytic characteristics analyzed by Brunauer-Emmett-Teller surface area, X-ray diffraction, N2-adsorption-desorption temperature programmed desorption NH3. effects operation parameters, such as pressure, activities investigated. affected considerably acidic properties catalysts, pressure. Higher acidity, high...
본 연구에서는 초임계수 가수분해로 얻은 당화액(액상 가수분해물) 내 발효저해물질(유기산, 퓨란계 화합물, 페놀성 화합물)을 제거하기 위하여 전기화학적 처리(전기분해 및 전기응집)를 수행하였다. 당화액의 전기분해 처리는 탄소 전극을 이용하여, 초기 pH 7, 전압 10 V, 전해질(NaCl) 농도 0.8%, 상온의 조건 하에서 반응시간 240분까지 실시되었다. 또한 알루미늄 이용하여 동일한 조건에서 전기응집 처리 실험을 하였고 종류에 따른 결과를 비교하였다. 실험 결과, 당 손실율은 두 처리법 모두 10% 이하(글루코오스 기준)로 낮은 수준이었으나 처리가 상대적으로 손실이 적었다. 화합물 제거율의 경우 전기응집에 비해 전기분해(약 80%)가 높은 나타냈다. 반면, 화합물은 처리에서(150분) 대부분 제거되는 경향을 나타냈는데, 전기분해시 일부 유기산으로 분해되는 확인했다. 유기산의 경우는 전기분해를 통해서만 제거되었다. 결론적으로 기작이 서로 다름에 따라 발효저해물질 제거율...
Catalytic pyrolysis experiments were conducted to investigate the possibility of obtaining valuable chemicals from Pinus densiflora, a native Korean tree species occupying 21.4% total area under forests in South Korea. Two representative mesoporous catalysts, Al-MCM-41 and Al-MSU-F, as well hierarchical MFI (Meso-MFI) that has both mesopores micropores, used catalysts. Compared non-catalytic pyrolysis, catalytic was shown reduce fractions levoglucosan, phenolics, acids bio-oil, while...
