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
Significantly higher surface area and much narrower pore size distribution in the mesopore region
A large amount of amine-type CO2 capturing agent into its mesopores in a well dispersed manner
Synthesis of MA

In catalyst, oxygen produced from H202
With sodium hydroxide, luminol Dianion is formed
The oxygen reacts with luminol dianion
This product is very unstable, so decomposes to 5-aminophathalic acid
As the exited state, 5-aminophathalic acid relaxes to ground state
Excess energy is emitted as blue light
Alkaline luminol, H2O2 solution is used on detecting NO2
The presence o
synthesis gas with silica catalyst
이 방법은 높은 압력과 높은 온도에서 silica catalyst의 rhodium을 이용하여, acetaldehyde를 생산하는 방법이다. 이것은 selectivity가 굉장히 낮으며, 상업적으로는 이용가치가 낮다는 문제점이 있다.
5) Reaction of methanol with synthesis gas

synthesis is usually an iron oxide mixed with a small amount of additional "promoter" material. When the process begins, the hydrogen gas converts the catalyst to pure iron. Gradually, as the iron catalyst is poisoned by carbon and sulfur compounds, it becomes less effective and must be replaced. Nitrogen gas for the synthesis process comes from the atmosphere, while most of the hydrogen needed i

Environmental Standards of the BTEX
Soil pollution worried standard.
= More than 80mg/Kg
Comparing with the amount of 장항습지.
By Methanol = 6.158ppm
By Hexane = 4.2020ppm
∴ The condition of 장항습지 is under
the soil pollution worried standard.
