Biomass vs. Oil & Other resources
Parameters Oil&Other Resources
Biomass
Availability Very limited & depleting In abundance
Location Geographical constraints Can be cultivated anywhere
Cost of fuel Very high, beyond out control
Very low, within our control
Capital cost High Normal
By Product Many Wood charcoal activated carbon
Environmental Unsafe Safe
Plant sizing Large in few 100MWe From 10KWe to few Mwe
Mode of plant Centralized Decentralized
Plant load factor High High
Biomass is a renewable energy in which the process can generate CO2 and recover CO2 to use again. But Fuel resource have diminishing and emitting CO2 to atmosphere increasing.
- Economical Benefits
- Reduced dependence on depleting fossil fuels
- Pollution free & Environment friendly source of energy
- Encourage energy plantation thus resulting in a green environment
- Increased national energy security using locally available fuels
- Provides a sustainable, affordable and eco-friendly alternative to fossil fuel
–2-Furfuraldehyde
–Acetone
–10% aq. NaOH
–Ba(OH)2
Set 3 reactions
1.Aldolcondensation of Fur by Ba(OH)2
2.Aldolcondensation of Fur by 10%aq. NaOH
3.Aldolcondensation of Fur by 10%aq. NaOH
1) Measure 0.5g of Ba(OH)2
2) Put it in a catalyst
3) Add a mixed solution of 5mmol Furfurals(0.414mL) and 50mmol Acetone (3.676mL) in the catalyst.
4) Stir it under room temperature for approximately 24 hours using the magnetic spinner.
5) After the catalyst is stirred for 24hours, set up a filter.
6) Filtrate the substance inside the catalyst, and wash it by acetone, to collect the left-over precipitates.
7) Dry the substance by Na2SO4.
8) Evaporate the acetone solvent.
9) Characterize the substance by the NMR technique.
1) Create a mixed solution of 5mmol Furfurals(0.414mL) and 50mmol Acetone (3.676mL) in a catalyst.
2) Add 3.2mL of 10%aq.NaOH to the catalyst.
3) Stir it under room temperature for approximately 24 hours using the magnetic spinner.
4) After the catalyst is stirred for 24hours, set up a filter.
5) Filtrate the substance inside the catalyst, and wash it by acetone, to collect the left-over precipitates.
6) Dry the substance by Na2SO4.
7) Evaporate the acetone solvent.
8) Characterize the substance by the NMR technique.
1) Create a mixed solution of 5mmol Furfurals(0.414mL) and 50mmol Acetone (3.676mL) in a catalyst.
2) Add 3.2mL of 10%aq.NaOH to the catalyst.
3) Stir it under room temperature for approximately 24 hours using the magnetic spinner.
4) After 24 hours of stirring, add 50mL of CH2Cl2 in the catalyst.
5) Exact the solution by 5% aq.HCl (2x25mL)
6) Keep the exacted solution in a beaker.
7) Wash the solution with H2O until it’s neutral.
Results
* Our result will show that the aldol-adduct occurs or not, and which methods have worked. We did three methods in all. The first result shows that it
can produce aldol adduct A-A (self-aldol condensation of acetone) F-A (aldol condensation between 2-furaldehyde and acetone in the same
equivalent) and F-A-F (aldol condensation between 2 equivalent of 2- furaldehyde and 1
eqiuvalent of acetone) that can be shown in data GC-MS
