biofuel production Flashcards
1
Q
Pre-treatment
A
Surface area of biomass increased by grinding substrate
2
Q
Enzymatic hydrolysis
A
Enzymes are added to break the bonds between monomers
3
Q
Fermentation
A
Oxygen removed to allow fermentation to occur
4
Q
Distillation and purification
A
Water is removed to create a useable biofuel
5
Q
food versus fuel
A
balance between increased production of biofuels and food availability - biofuels need to be made using waste products from plants
6
Q
land requirements
A
increase in demand for land for fuel is expected to occur at the same time as global production increases
7
Q
energy efficiency
A
energy required to produce and then collect the raw materials required is far greater than the fuel produced.
