화석연료로부터 기인한 환경오염에 대한 대응과 더불어 신재생에너지 공급의무화제도의 시행은 재생연료유 등 신재생에너지의 활용도를 증대시켰다. 부생연료유(2호)와 정제연료유(감압)는 국내 법령으로 엄격히 규제되고 있으며, 부생연료유(2호)를 혼합한 정제연료유(감압)의 물성변화를 시험하였다. 부생연료유(2호)를 1 : 1로 혼합한 정제연료유(감압)의 물성분석 결과, 국내 폐기물관리법에서 규정하고 있는 품질기준을 만족하였다. 다만, 연료와 관련한 추가항목 시험결과에서 높은 방향족 함량을 나타내었다. 연료내 높은 방향족 함량은 사용기기의 고무류 파손이나 연소 시 그을음, 매연 등이 발생할 가능성이 높을 것으로 보인다.

In addition to responding to the environmental pollution caused by fossil fuels, the enforcement of Renewable Fuel Standard(RFS) system has increased the utilization of renewable energy such as refined fuels oil. The by-product fuel oil(No. 2) and the refined fuel oil(reduced-pressure) are strictly regulated by the domestic legislation and the chemical property changes of the refined fuel oil(reduced-pressure) mixed with the by-product fuel oil(No. 2) were analyzed. As a result of analyzing the physical properties of refined fuel oil(reduced pressure) obtained by mixing 1 : 1 of by-product fuel oil(No. 2), it satisfied the quality standards stipulated by the domestic Enforcement Decree of the Wastes Control Act. However, the results of the additional tests related to the fuel showed a high aromatic content. The high content of aromatic in a fuel is likely to cause the soot and ehaust emission gas during the combustion of the used equipment.
