  • Interest in renewable fuel of recent has increased. Among them, From next year the government announced that it would enforce the RFS. Interest associated with it are concentrated. The RFS, for manufacturers of transportation fuels such as a vehicle, you are a renewable fuel a certain percentage of the fuel supplied. In other words, it refers to a system of mandatory to supply by mixing biofuels. Already in Europe, America and other developed countries to diversify energy sources and subjected Additionally there since ancient times for its rural development by introducing the RFS takes effect coming. Further and inspect to deal with climate change, which is performed via the RFS. Some even are represented by five axis of the sustainability of the RFS.

  • Recently, the government is actively promoting the RFS(Renewable Fuel Standards) and RPS(Renewable Portfolio Standards). Therefore, the importance of renewable energy fuel is being highlighted more than ever. Now is the time required active research in Korea. Since power bio-fuel oil demonstration project is underway dissemination to meet RPS quota. In this study, we investigated emission performance to make the performance standard draft of bio-fuel oil. In addition, the quality properties of the fuel oil and bio-oil, and after combustion in industrial boilers and compared the amount of exhaust gas. It was reduced emissions of bio-oil in industrial boilers due to bio-fuel properties as compare with fuel oil.

  • In these days, many countries carry out many renewable energy policies to increase the renewable energy portion and to reduce the GHG(Green House Gas). In Korea, RPS(Renewable Portfolio Standards) focused on over 500MW power producers is conducting. And they are using the bio-fuel oil to meet their RPS quota. The oil is a mixture of animal and vegetable fat or fatty acid ester of them and should satisfy some specifications to use the power generation such as viscosity, pour point, acid number. Depends on the raw materials, quality characteristics of power bio-fuel oil are changed. By adding the power bio-fuel oil, pour point, density, sulfur content and viscosity are decreased and acid number, iodine number, oxygen content are increased. In this study, we test the quality characteristic of power bio-fuel oil and the property changes by the blending ratio of power bio-fuel oil & conventional fuel oil.

  • Transport biofuels produced from biomass can be substituted for petroleum fuels due to GHG reduction, sustainability and environmental friendly. Mandates and targets of biofuels are announced in the European union, United states and other countries worldwide and promoted by the government policies. This paper reviewed current status of the national biofuels policies and fuel specifications in transport sector. EU biofuels policy shifted and GHG emission reduction became the main focus of the policy. There are specification requirements for biofuels in the U.S. under the RFS2, but there are other polices as well that serve to promote the uptake of biofuels both at the federal and state level. Korea government has allowed 2.3% oxygen in gasoline to come from oxygenates, increased the biodiesel blend mandate from B2 to B2.5 effective from Jul. 31, 2015.

  • To reduce the effects of greenhouse gas (GHG) emissions, the government has announced the special platform of technologies as parts of an effort to minimize global climate change, and the government distributed biodiesel since 2006 as the further efforts. Although there are some debates about some quality specifications and unbalanced of source (44% from palm oil), more than 400kton/year of biodiesel was produced in 2013. Moreover the amounts will be increased when the RFS is activated. To solve the unbalanced situation and to achieve the diversity of feeds, it is essential that many researches should be considered. Especially, free and bond glycerines are one of the important properties seriously affected to the combustion system in vehicle & cold properties. Previous method (KS M 2412) couldn't cover the biodiesel derived from lauric oil($C_{12:0}$) such as PKO (Palm Kernel Oil), Coconut oil because those compositions are lighter than other conventional biodiesel sources. In this study, we review the existed method and figure out the factors should improve to analysis the glycerine from PKO and Coconut oil biodiesel. Modifying the analysis conditions to enhance the resolution and change the internal standards to avoid the overlapped- peaks between Capric acid ME ($C_{10:0}$) and standard#1(1,2,4-butantriol). From this revised method, we could solve the restrictions of previous methods. And check the possibility of new method to analyze the glycerine in biodiesel regardless of sources.
