Introduction
At the very end of 12th grade you have to study about Ethanol production. This process is not simple, but very interesting.
The easiest way to understand this hard process is to watch animated video which will help you to learn and also entertain you. After watching the video, you will have to complete the task and you will be evaluated. Good luck!
Task
Answer the questions!
1. How do we call materials ethanol is made of?
2. What is the second enzyme that you put into the mash?
3. What you must do with the mash before adding second enzyme?
4. How many hours does it take to mix the mash and yeast?
5. After mixing mash and yeast, how many percents of ethanol mash are there?
6. How do you extract those percents of ethanol?
7. How many proof ethanol can not be portable?
8. What do you put there to make it portable?
9. How is the process in a previous question called?
10. How many percents of ethanol are there in a E85 fuel?
Process
You are going to watch a video material: https://www.youtube.com/watch?v=59R-NqykoXs
Then answer 10 questions that are given! Questions might be connected to each other, so you should do them in chronological order. Answers should be short.
Evaluation
Correct answers are:
1. cellulosic materials
2. glucoamylase
3. cool the mash
4. 48 hours
5. 10% ethanol mash
6. by cranking up the heat
7. 200 proof
8. 2% - 5% gasoline
9. denaturing
10. 85% of ethanol
If you have got 8 to 10 correct answers, you are now a professional in the topic of ethanol production!
If you have got 5 to 7 correct answers, you need to revise just a little bit more, but you are already doing good!
If you have got 4 - 0 correct answers, you need to watch the video again to improve your knowledge.
Conclusion
Congratulations!
I hope now it is clear for you what ethanol is and how do we make it! The task made you think of each process in ethanol production and explained why you should do certain steps to make a good ethanol.
To improve your knowledge in this topic even more, I suggest you reading your students book paragraph 5.2. ,it has a lot of vitally important information.
