- Biofuels
- FUELS can be made by FERMENTATION
- natural/waste products
- Fermentation :the reaction in which the ENZYMES in YEAST turn GLUCOSE (sugar) into ETHANOL and CO2
- anaerobic respiration
- ETHANOL is made by ANAEROBIC fermentation of SUGAR
- GLUCOSE ---------> ETHANOL + CARBON DIOXIDE + ENERGY
- glucose derived from MAIZE STARCH by the action of carbohydrase
- OR use SUGAR CANE juices
- Ethanol DISTILLED to separate from yeast and glucose before use
- GASHOL , Brazilian car fuel (petrol+ ethanol)
- BIOGAS is made by ANAEROBIC fermentation of WASTE MATERIAL
- 70% Methane and 30%
- different micro-organisms used
- they ferment plant and animal waste (containing carbohydrates)
- Sludge from sewage plants/ sugar factories is used on LARGE SCALE
- they ferment plant and animal waste (containing carbohydrates)
- Untitled
- made in simple fermenter : DIGESTER or GENERATOR
- need to be kept at constant temp.
- for respiring mirco-organisms
- BATCH or CONTINUOUS
- need to be kept at constant temp.
- can't be stored as liquid, has to be used straight away
- heating
- cooking
- lighting
- power a turnbine
- generate electricity
- Fuel production LARGE/SMALL scale
- large
- country
- small
- village/family
- human waste form keeping pigs and food waste can be digested by bacteria
- to produce Biogas
- By-products to be used as fertilisers
- to produce Biogas
- large
- FUELS can be made by FERMENTATION
