Question

Could you give me some tips on responding to these questions?

1.What is the main difference of sugar-based ethanol production and cellulosic-based ethanol production?

2. How biomethane can be produced from agriculture waste?

3. Can enzymatic treatment replace the heat and chemical treatments to produce fuels from lignocellulosic materials? Explain.

4. Why would farmers grow cellulosic crops with only a few cellulosic plants in operation and with markets too far away to haul biomass?

5. What are the routes to produce BioGas?

Answer 1

1. Sugar and cellulose both are carbohydrate and converted in to single sugars and forms ethanol. Corn kernels are used up to form sugar-based ethanol and  cellulose is used for the formation of cellulosic-based ethanol. The alpha-amylase enzyme break down starch into glucose, then glucose is converted into ethanol by the yeast.

Ethanol production by the cellulosic biomass is much slower and more complicated than sugar-based ethanol production. We get the predictable amount of alcohal during sugar-based ethanol production but the amount of cellulosic-based ethanol production varies with the plant.
