BIO DIESEL PART-2

[PRAKASHKUMAR]

This almost similar to my first project.
in this project there will be 100m*100m 20 storeyed building in with methanol plants will grow. it may be sugar can, switchgrass etc.
there will be solar panels for energy requirements.
A water treatment plant for meeting the water requirements.
A biogas plant which will produce methane ( used as a cooking fuel) and organic waste( used as a fertilizer).
A plant where fermentation process will take place. plants will be decomposed here and methanol and carbon dioxide will be made.
carbon dioxide will be collected and used in food industries, oil industries , fire extinguishers etc.

Biggest problem which plant should i choose like sugarcane switchgrass or corn etc.
Should i produce methanol or ethanol or biobutanol?
which is a good fuel?

Hi,

One of the benefits of using plants for methanol and biogas production is that you can use any type of plant material, so you should use the plant that will grow best in your climate. That will ensure the optimum yield of plant material. Also, if you are using a plant that is used as a food crop, you will use the part of the plant that is not used for food. What would be the most valuable crop that you could grow that would yield a large quantity of biomass? It could be either switchgrass or corn.

A project like this has many technical challenges that have not been solved yet. One problem is the separation of the cellulose from the rest of the plant material; another problem is the method for hydrolyzing the cellulose into glucose. Here are a couple of references that reviews these challenges.:

What are you going to do in your project that will solve some of the problems and make the production of biofuel more cost effective?

The production of either biogas, methanol, ethanol, or butanol would be worthwhile. What product do you think would be most valuable? If you are going to use a ferementation method, you will need to provide optimum conditions for the fermentation process? How will you do this?

sir,
i am confused which is most valuable?in our climate every plant grows.
sir so which plant should i choose?according to you?

there will a large chamber in which plant raw materials will be kept. will be remove oxygen from the air or provide air which is absent of oxygen.then will be add (Kluyveromyces lactis, Kluyveromyces lipolytica)yeast to make fermentation process work. then we will get ethanol and carbon dioxide.

Hi,

I have not been able to find any information to indicate that one plant would offer an advantage for ethanol production compared to another plant. The amount of ethanol produced will be proportional to the amount of cellulose in the plant, so if you can find information on this topic, it would help you make the choice. The problem with any plant material is that the cellulose is trapped inside a lignin matrix, so sample pretreatment is necessary to make the cellulose available for hydrolysis and for fermentation. Also, I don't believe that Kluyveromyces can hydrolyze cellulose, so you will need some way to break down the cellulose to glucose so it will be available for the organism to use.
