- Ethanol Production
- Synthesis
- Fractional distillation of crude oil
- Ethene+ Steam = ethonal
- A catalyst is used to speed up the reaction rate
- Ethene+ Steam = ethonal
- Advantages- 100% atom economy - all products & used and resused
- Disadvantage-Uses unrenewable resources & is unsustainable
- Fractional distillation of crude oil
- Biotechnology
- Using waste biomass & genetically modified enzymes
- E.g.- rice hulls, corn stalks & wood waste
- Optimum conditions - constant ph and temp 25-37
- Otherwise enzymes will denature
- Advantage- Carbon neutral & uses renewable sources
- Disadvantage- Large amounts of energy are required for the reaction to take place
- Using waste biomass & genetically modified enzymes
- Fermentation
- When distilled purer alcohol e.g. whisky & brandy are made
- Using enzymes in yeast
- Temp & Ph have to be specific
- Oxygen cannot be present
- Enzymes will be denatured if the alcohol is to high in concentration
- Temp & Ph have to be specific
- Advantage- The process is carbon neutral
- Disadvantage- It uses a lot of land & human food produce
- The process is slow
