  • To examine the effects of amendments on heavy mineral oil degradation, a pilot scale experiment was conducted for over 105days. During the experiment, soil samples were collected and analyzed periodically for the determination of residual hydrocarbon and microbial activities. At the end of the experiment, the initial level of contamination ($6,205{\pm}173mgkg^{-1}$) was reduced by $33{\sim}45%$ in the amendment amended soil; whereas only 8% of the hydrocarbon was eliminated in the non-amended soil. Heavy mineral oil degradation was much faster and more complete in compost amended soils. Enhanced dissipation of heavy mineral oil in compost amended soil might be derived from increased microbial activities (respiration, microbial biomass-C) and soil enzyme activity(lipase, dehydrogenase, and FDA hydrolase) were strongly correlated with heavy mineral oil biodegradaton (P < 0.01).

  • Most researches regarding emulsified fuel were in the areas of emulsifier, emulsified fuel manufacturing and emulsified fuel droplet combustion, but there were little papers published regarding emulsified fuel combustion and boiler efficiency in an industrial boiler. The main purpose of this study is to clarify whether improvements in the boiler efficiency and the reduction of pollutants such as CO, NOx, SOx and smoke exist or not when emulsified fuels are combusted in the commercial boiler. Main experimental parameters were water content in heavy oil , excess $O_2$, and boiler load. The fuels used in this experiment were 0.5 B-C, and 5 kinds of 0.5 B-C/water emulsified fuels. The combustion characteristics of heavy oil and its emulsions with water were investigated in an industrial boiler. The combustion stability was monitored and exhaust gases such as CO, NOx, SOx and smoke were measured with excess $O_2$ and combustion load. In case of emulsified fuel combustion, flame stability was poor and boiler efficiency was lowered by 1.6~5.7%, but emission levels of CO and smoke were improved.

  • An exothermic oil absorbent sheet with calcium chloride crystals can be fabricated, by dipping a clean polypropylene fabric in calcium carbonate and hydrochloric acid solution and drying it. The exothermic oil absorbent sheet applied to the seawater surface, releases heat by the dissociation of calcium chloride. The dissociation heat liquefies the solidified low-sulfur fuel oil at a low temperature, and converts it to a state at which it can be absorbed. The optimum mole concentrations of calcium carbonate and hydrochloric acid required for the exothermic oil absorbent sheet, are 0.25 M and 0.5 M, respectively. The oil absorption capacity of the exothermic oil absorbent sheet for low sulfur fuel oil depends on the seawater temperature. But, it is highly excellent at 4.5-7.08 g/g at 10℃, the average seawater temperature during the winter in Korea. The exothermic oil absorbent sheet is an excellent alternative in absorbing low-sulfur fuel oil in winter and removing it from seawater.

  • Middle distillate was produced by the hydrocracking of F-T wax on the zeolite catalysts. Novel metal loaded zeolite catalysts had good performance for hydrocracking of F-T wax. 2 wt.% Platinum loaded H-Y zeolite catalyst showed the highest selectivity of middle distillate and conversion of F-T wax. H-Y zeolite had more strong acidity site and large pore than that of another zeolite catalyst. So, H-Y zeolilte catalyst showed the best activity for hydrocracking of F-T wax.

  • 오일샌드는 아스팔트와 같은 중질유를 10% 이상 함유한 모래 또는 사암으로서, 겉으로 보기에는 시커먼 흙이나 모래처럼 보이나 내부에는 모래(점토)와 같은 광물질이 70~80%, 에너지원으로 활용이 가능한 중질유 성분인 bitumen이 10~18%, 물이 3~5% 정도 혼합되어 있다. 본 연구에서는 이러한 오일샌드 활용방안 개발을 위하여 오일샌드로부터 bitumen의 추출 및 증류 특성에 대한 시험을 진행하였으며, 가스화를 통한 합성가스 제조, 합성가스 중 분진제거 및 탈황, CO/$H_2$비 제어를 위한 합성가스 전환 등의 시험을 진행하였는데, pilot급 시스템을 이용한 합성가스 제조 시험 결과 중질잔사유를 5~7 kg/h 공급하는 조건에서 CO 40~50%, $H_2$ 20~30%, $CO_2$ 10~20% 조성의 합성가스 18~22 $Nm^3$/h를 제조하였다.

  • Non-conventional energy is considered as important future energy source, as conventional energy has limitation for its capacity. The demand on value added process in heavy oil/oil sand bitumen is increasing in particular. Solvent Deasphalting (SDA) process for Deasphalted Oil (DAO) is used as heavy oil upgrading process in existing refinery process. SDA process for heavy oil upgrading has been already commercialized by leading countries. SDA R&D projects have been carried out actively by those countries. In this study, patent analysis for SDA technology development was carried out. From 1970's, when SDA patents were applied, the patents in Korea, USA, Japan, Canada and Europe were searched and distributed to extraction, recovery, solvent and etc. 334 patents were selected relating to heavy oil upgrading SDA process. The application status of SDA process patents showed a tendency to increase slightly. The number of patent applied was USA patent 131 (39%), Canada patent 83 (25%), Japan patent 35 (11%) and Korea patent 6 (2%). It will be necessary for efficient use of energy resource to support SDA R&D by government.
