우리 나라는 거의 모든 사료원료를 외국으로부터 구매하여왔고, 앞으로도 그럴 전망이므로 배합사료공장에서의 원료 구매 업무는 국제적으로 다변화되어야 한다. 지금까지 우리 나라에서 구입한 사료원료는 세계적으로 널리 사용되고 있는 전통적 사료자원으로서 비교적 가격이 비싸기 때문에 이와 같은 전통적 사료원료를 가지고는 우리나라의 배합사료 원가를 절감시킨다는 것은 대단히 어려운 일이라고 생각된다. (중략)

Korea is the urgent need to diversify the bio-energy raw materials because we have narrow area of land cultivated plants and lack the bio-mass resources. Using a resource-rich the marine environment enclosed on three sides by the sea. Through bio-energy production-technical and carbon dioxide reduction measures which will be a very effective alternative. Sustainable development about algae bio-energize industry through SSaM-GG(Smart, Shared and Mutual-Green, Growth) is expected. Algae has high carbon dioxide absorption factor, extracting oil from algae is thirty times much more than sunflower.

그 동안 석유의 그림자에 가려서 등한시 되어온 LPG는 최근 일종의 대체에너지로서 각광을 받고 있으면, 국내 수요도 매년 급증하고 있다. 일반 가정용에서 도시가스, 석유화학원료로서 그 이용분야는 확대일로에 있으며, 에너지로서 차지하는 비중은 그 만큼 높아지고 있다. 이 자료는 최근 일본의 「석유정책」지가 특집으로 엮은 LPG관계논문을 옮긴 것이다. 이 특집은 일본의 LPG수급과 관련하여 공급안정책과 가격정책을 심층적으로 분석하고 있어 많은 도움이 되리라고 생각한다. <편집자주>

The objective of this study was to investigate the quality characteristics of spirits derived from fruit using copper distillation equipment. First, optimal yeast strains were chosen through a fermentation test on raw materials (apples, mandarins and rowanberries). The normal fermentation condition for rowanberries observed at a rowanberry concentration of 8% during mashing included chaptalization with sugar to increase the alcohol content. During the mashing, fruits were fermented and distilled through one of three different types of distillation apparatuses (pot distiller, vacuum distiller, or multistage distiller made of copper). The results revealed that the type of apparatus used affects the content of alcohol and flavor components. The distilled spirits prepared through a copper multistage distiller had a much higher tendency to retain components of fruit aromas such as ethyl acetate and provided higher yields than spirits prepared with a pot distiller or vacuum distiller. Thus, the copper multistage distiller apparatus can be applied to positively influence the taste and flavor of fruit distilled spirits by enhancing fruit aromas, removing impurities such as sulfur components and enhancing yields.

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.

The status of biodiesel (BD) production and consumption, specifications and market status in Korea are discussed in this review. The main feedstock to produce BD is soybean oil and waste cooking oil in domestic, and some companies have tried to diversify BD feedstocks. Ministry of Agriculture and Forestry (MAF) has begun a pilot project to produce BD feedstock from rapeseed for 3 years since 2007. In July 2006, Ministry of Commerce, Industry & Energy (MOCIE) and the domestic oil industry reached an agreement under which BD0.5 is supplied in market, and 158400 MT of BD would be supplied between 2007 and 2008. MOCIE reported that it will increase BD 0.5% every year to reach BD3 by 2012. It is expected that BD supply would continuously increase domestically in the future.

Coal gasification process, which had developed originally to convert coal from hydrogen and carbon monoxide, has used and developed in many countries because of environmental advantages such as carbon dioxide storage, decrease of pollutants and so on. Generally entrained-flow gasification process using pulverized coal under $75{\mu}m$ is used in Integrated Gas Combined Cycle(IGCC) because of easy scale up and high efficiency of energy conversion. Especially entrained-flow gasifers with coal water slurry have been used in many applications due to its fully developed technologies. In this paper, several technologies for coal-water slurry gasification that involves slurry preparation, burner, gasifier, slag melting and numerical simulation for plant design and operation were investigated. Entrained-flow gasification with coal water slurry can be used for synfuel production, SNG, chemicals as well as IGCC. To develop hybrid gasification process and use different types of coal, it is necessary to develop new technologies that will increase efficiency of the process.
