석유: 천연적으로 생성되는 탄화수소를 주성분으로 하여 탄화수소의 황, 산소 및 질소 유도체들이 혼합된 비균질 혼합물
– 석유는 불순물로 수분과 가스분을 함유
– 수출 또는 정유공장으로의 이송에 앞서 보통 간단한 처리를 거쳐 수분과 가스분을 제거하는데, 특히 이를 석유라고 부름
– 석유와

Petroleum compounds have a uniform chemical structure. SO it is easy for the plastic composite.
In contrast, lignin is an irregular and complex structure. Chemical synthesis is difficult and was not being used.

Six million dollars is a small amount in the gasoline market. The United States consumes well over 20 million barrels of oil a day. Replacing some of this oil with ethanol seem, so far, to be the most feasible solution to reducing the country’s dependence on petroleum.
Today, most cars on the road can use a mix of 10 percent ethanol and 90 percent gasoline. But the car industry is rapidly chan
