Highly ordered mesoporous tungsten trioxide ( WO 3 ) with high surface area (75 m 2 /g) and well-defined mesopores were successfully prepared through a hard templating method using silica KIT-6 as template NH 4 6 H W 12 O 40 ⋅ x precursor. Oxidative desulfurization of model oil the oxidant was carried out at 50°C under atmospheric pressure in order to analyze catalytic activity. The reactions optimized by various kinds reaction parameters such / S molar ratio, temperatures series...
Selective hydrogenation and ring opening (SRO) of tetrahydronaphthalene (tetralin) was studied over nickel iridium supported catalysts in the context removal polynuclear aromatics from diesel fuel. The tetralin carried out a fixed‐bed reactor at 270°C, using H 2 pressure 30 bars, WHSV 2.3 h −1 , /feed molar ratio 40; resultant products were analyzed by GC GC‐MS. Ir/SiO catalyst gave 85% conversion 75.1% decalin selectivity whereas Ni/SiO showed an unprecedented high catalytic performance...
Electric double-layer capacitors have attracted considerable attention for energy storage because of their excellent power capability, high stability, and long cycle life. Activated carbon is the most widely employed electrode material electric owing to its specific surface area, hierarchical porous structure, electrical conductivity. However, increase density devices, new synthetic methods enhancing capacitances are required. We developed a facile preparation method petroleum pitch-based...
오일샌드에서 비투맨(bitumen)을 회수하는 지하회수방식 중 가장 많이 사용하는 기술인 SAGD (steam assisted gravity drainage)공정으로부터 비투맨의 회수율을 향상시키고자 스팀과 함께 주입한 첨가제의 효과와 매커니즘에 대해서 연구하였다. 실제 광구에서 쓰이는 SAGD공정을 150 : 1로 축소한 실험실 규모의 모사장비가 사용되었으며, 지하 박층을 모사할 수 있는 장치(이하 GM, geological model)가 사용되었다. 초중질유와 글래스비드(glass bead 1.5 mm)의 혼합물은 오일샌드의 모사재료로 첨가제로서 <TEX>$CO_2$</TEX>가 스팀 챔버(steam chamber)의 성장 변화를 비교 분석하였다. <TEX>$CO_2$</TEX>의 주입방식에 따른 효과를 확인하기 위하여 <TEX>$CO_2$</TEX>를 연속 주입하는 실험(<TEX>$cCO_2$</TEX>-SAGD)과 순차적으로...
박층의 오일샌드에서 비투멘 성분 회수를 위한 steam assisted gravity drainage 공정에서 무기첨가제 도입에 따른 오일 회수율 특성을 평가하고자 실험실 규모의 모사장치를 이용하여 모사된 오일성분을 회수하는 실험을 수행하였다. 오일샌드 모사를 위해 비투멘과 성질이 유사한 초중질유와 직경 1.5 mm의 글래스비드를 사용하였다. 무기합성법을 통해 <TEX>$FeO_X$</TEX>를 제조하여 무기첨가제로 도입하였다. 그 결과 시간에 스팀의 열전달 속도는 따라 약 40% 증가하였으며, 또한 30% 증가하였다. Lab scale simulated (SAGD) process devices were used to investigate the effect of inorganic additives for bitumen recovery from oil sand. An extra heavy similar with and mm diameter glass bead instead...
