고유가 시대를 맞이하여 석유류를 대체할 연료의 필요성이 대두되고 있다. 한편 석유로부터 나오는 농가의 폐비닐이나, 산업폐기물 중 가전제품 및 산업용 폐플라스틱의 증가로 재활용에 대한 요구가 증대되고 있다. 일본 등에서는 이미 RPF를 연료로 사용하는 것이 보편화 되고 있어, 사람이 섭취하는 다이옥신의 98%는 음식, 1.5%는 대기 중에서 섭취하며, 소각장치에서 다이옥신류의 생성 억제 및 제거 기술은 이미 많이 확보되어 있다. RPF를 효과적으로 생산하고 열병합 발전소, 대형 보일러 시설, 작게는 농가의 대형 비닐하우스 등에 사용하기 위한 체계적인 연구가 필요하며, 본 논문에서는 W 기업의 플랜트 설비를 이용하여 폐플라스틱에 음식물류폐기물을 혼합한 RPF의 제조 및 연소특성을 중심으로 고찰하였다.

RDF(Refuse-Derived Fuel) is a fuel of pelletized form made of combustible solid wastes and can not only be used as alternative energy to fossil fuel but also solve troubles in thermal uses of incinerator. As the first stage for obtaining elementary data required to develop criteria of raw materials appropriate to RDF combustion facilities actively spread recently in Korea, preliminary experiments were conducted on CO, SOx, NOx and HCl production and reduction characteristics in combustion of RDF. RDF samples weighing 2~3 g per a sample were manufactured in a lab-scale way and combustion tests of RDF were carried out in electric furnace with quartz tube of 50 mm inside diameter.

An experimental study on the hydro-cracking of recycling oil obtained from refused plastics was performed for up-grading of its fuel characteristics. Major experimental parameters were reaction temperature ($300^{\circ}C{\sim}700^{\circ}C$) and presence of catalysts (Al-Si, activated carbon, zeolite). The effect of the experimental parameters on the liquid product characteristics such as flash point, kinetic viscosity, and solid content was investigated. The hydro-cracking reactions of the recycling oil at $300^{\circ}C{\sim}400^{\circ}C$ improved the oil characteristics of the liquid products. Activated carbon was revealed as a stable and active catalyst in the hydro-cracking reaction at a temperature range investigated.

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.

The co-combustion of coal and RPF(Refuse Plastic Fuel) mixture has been experimented in a commercially operating CFB coal boiler and the emissions such as SOx, NOx, TSP and dioxine were measured at the stack. The experimented RPF was supplied by domestic RPF company that is commercially producing RPF pellet from the wasted plastics. Up to 15% of total coal was substituted to RPF and no trouble was happened during normal boiler operation. SOx and NOx concentration was reduced about $15{\sim}20$% and TSP(Total Suspended Particle) was drastically reduced about 30% during co-combustion. Dioxine concentration at mixing ratio of 7.5% was $0.0487ng{\sim}TEQ/Sm^3$ ($O_2$, 12%) that satisfied governmental emission regulation.

Waste plastic differs in its speed of combustion owing to its variety in composition as well as kinds of plastic. This study is aimed at examining the thermal weight analysis and determination of its kinetics in order to derive the design element in pyrolysis of RPF (Refused Plastic Fuel) as the plastic solid fuel. Based on the result of TGA (Thermogravimetric analysis), kinetic characteristics were analyzed by using Kissinger method which are the most common method for obtaining activation energy, and experimental conditions of TGA were set as follows: in a nitrogen atmosphere, gas flow rate of 20 ml/min, heating rate of $5{\sim}50^{\circ}C/min$, and maximum hottest temperature of $800^{\circ}C$. The method used for determining the property of waste plastic when thermally decomposed was thought feasible as the basic data in deciding the performance, design, and optimal operating condition of the reactor in the actual reactor.
