Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial
PHB`s Separation & Purification
Target of this study conducted to obtain a purely material PHB purification process debris in the damaged cells, and to remove the remaining medium components. PHB has been removed during the refining process with just remove the present efficiency of the overall purification stayed in the 70-80%.

열교환기를 통하여 흐름이 부분적으로 액화되었다. Raoult's law를 통해 액화된 양과 조성을 계산하였다. Raoult's law의 적용에 필요한 증기압력 설정을 위해 열교환 후 온도는 기존의 공정에서의 온도를 참고하여, -153℃로 설정하였다. Stream 103은 stream 102의 기상, stream 104는 stream 102의 액상
it winds its way through the tank.
As the wastewater goes through the system, BOD and organics concentration are greatly reduced.
Variations to this method include: adding return sludge and/or in decreasing amounts at various locations along length of the tank; wastewater BOD is reduced as it passes through tank, and air requirements and number of bacteria required also decrease accordingly.
purification technique에 사용이 되고 mixture로부터 원하는 compound를 분리, 정제하는 방법이다.
Column chromatography로 분석하고자 하는 mixture는 column material의 가장 윗부분에 loading된다. Solvent (eluent)는 gravity나 air pressure에 의해 column을 통과한다. Column 아래로 내려가면서 adsorbent에 adsorption이 되어 있는 solute와 colum
air circulates, the coated surfaces contact with the silver ions which can resist any airborne bacteria, which in turn suppress the respiration of bacteria, adversely affects bacteria's cellular metabolism and inhibits cell growth.
