The target of this work was the process development of demonstration plant to produce the high quality alternative fuel oil by the pyrolysis of mixed plastic waste. In the first step of research, the bench-scale units of 70 t/y and the pilot plant of 360 t/y had been developed. Main research contents in this step were the process performance test of pilot plant of 360 ton/year and the development of demonstration plant of 3,000 t/y, which was constructed at Korea R & D Company in Kimjae City. The process performance of pilot plant of 360 t/y showed about 80% yield of liquid product, which was obtained by both light gas oil(LGO) and heavy gas oil(HGO), The boiling point range distribution of LO product that was mainly consisting of olefin components in PONA group appeared at between that of commercial gasoline and kerosene. On the other hand, HO product was mainly paraffin and olefin components and also appeared at upper temperature distribution range than commercial diesel. Gas product showed a high fraction of C₃;and;C₄ product like LPG composition, but also a high fraction of CO₂ and CO by probably a little leak of process.

최근 정부의 저탄소 녹색성장 정책, 신재생에너지의무할당제(RPS)의 시행 추진, 국제 유가의 지속적인 상승 등으로 인해 폐자원 에너지화에 대한 관심이 높아지고 있다. 이와 관련하여 에너지를 많이 소비하는 업계에서는 폐기물 고형연료의 사용을 추진하고 있고, 특히, 폐플라스틱의 열분해유화기술은 중소, 중견기업들이 국내에서 개발된 기술의 상용화를 적극적으로 검토하고 있다. 본 논문에서는 폐플라스틱 열분해 기술의 소개와 폐플라스틱 자원, 기술 개발 및 상업화 등에 대하여 국내의 현황을 소개하였다. Recently, the waste energy utilization has become the main interest in energy industries, due to high oil prices, the low carbon, green growth policy and the RPS (Renewable Portfolio Standards) of our government. Therefore, energy guzzling companies such as district heating companies, textile industries are replacing energy to RDP/RPF. Especially, a lot of big companies are carrying out survey to commercialize the waste plastics pyrolysis technologies developed in Korea. In this paper, status of the pyrolysis technology of Korea were reviewed overall including basis of technology, waste plastics resources, research & development, and commercialization.

오일샌드는 원유성분이 함유되어 있는 모래로 종전에는 높은 생산비용으로 인하여 큰 관심을 받지 못했지만, 최근 초고유가 시대를 맞아 새로운 대체 원유로서 세계적으로 주목받고 있다. 본 연구에서는 오일샌드로부터 합성원유 생산과 관련되어 한국을 포함하여 미국, 캐나다, 일본, 유럽, 중국에서 공개된 출원특허를 대상으로 분석하였고, 전체기술을 채굴, 추출, 개질, 연료화, 기타 기술로 나누어 세부기술 분석을 실시하였다. 오일샌드로부터 합성원유 생산 기술에 관한 특허는 1969년에 첫 출원이 이루어진 후, 꾸준히 출원건수를 보이고 있으며 특히 국제유가변동 추이에 출원건수가 영향을 받는 것으로 나타나고 있다. 미국과 캐나다 특허의 점유율이 전체의 약 90%로 오일샌드 기술을 주도하고 있음을 알 수 있다. 전체 기술 특허 중 추출 기술과 채굴 기술이 77% 이상을 차지하여 가장 활발한 활동을 보였지만, 2000년대 이후에는 출원건수가 감소하거나 일정한 양상을 보이고 있다. 반면, 개질 기술은 출원건수가 최근 들어 증가하고 있는데. 이는 근래에 관련 기술 중 개질 기술에 대한 연구가 활발함을 나타내고 있다. Oil sands are sands containing bitumen similar to crude petroleum. Oil sands had not received enough interest because of the high production cost. However, in the current record-high oil price situation, oil sands are considered as new sources for unconventional oil. In this study, patents analysis was performed for the technologies of production of synthetic crude oil from oil sands. The patents covered were open patents applied in Korea, US, Canada, Japan, Europe, and China. The patents were divided into five detailed technologies; mining and in-situ, extraction, upgrading, fuelling, and other technologies. For oil sands technologies, there have been steady patent applications, since the first patent was applied in 1969. The number of patents applied appeared to be affected by the variation of world oil price. The portion of patents applied in US and Canada was about 90% of the overall patents and it means 05 and Canada have led oil sands technologies. Mining and in-situ technologies, and extraction have been developed actively and occupied more than 77% of the overall patents. However, the number of patents applied for mining and in-situ technologies, and extraction has been constant or started to decrease since 2000. The number of patents applied for upgrading technologies increases recently and it shows the development of upgrading technologies is active now.

This study is aimed at substantially reducing the particulate matter (dust) emission during the combustion of heavy fuel in boilers by addition of combustion improver. The combustion improver used were the oil-soluble organometallic compounds that were found to be more effective than the dispersing agents that are generally used for reducing the particulate emission. The dust reduction effect was found to depend on the active materials (metals) as well as on the organic ligand part of organometallic compounds. Acetylacetonoate and naphthenate of Fe and Ca were found to be most effective for dust reduction. Addition of Fe and Ca organometallic compounds as combustion improver in concentration of 30 ppm (metal basis) to heavy fuel oil, caused dust reduction by 50 wt% to 80 wt%.

In response to environmental demands, pyrolysis is one of the practical methods for obtaining reusable oils from waste plastics. However, the waste plastic pyrolysis oils (WPPO) are consumed as low-grade fuel oil due to their impurities. Thus, this study focused on the upgrading method to obtain naphtha catalytic cracking feedstocks from WPPO by the hydroprocessing, including hydrotreating and hydrocracking reaction. Especially, various transition metal sulfides supported catalysts were investigated as hydrotreating and hydrocracking catalysts. The catalytic performance was evaluated with a 250 ml-batch reactor at 370~400 ℃ and 6.0 MPa H<sub>2</sub>. Sulfur-, nitrogen-, and chlorine-compounds in WPPO were well eliminated with nickel-molybdenum/alumina catalysts. The NiMo/ZSM-5 catalyst has the highest naphtha yield.
