Bioethanol (VCE SSCE Chemistry): Flashcards

Ethanol produced from biological sources (biomass)

35°C (higher temps destroy enzymes & microorganisms)

$C_6H_{12}O_6 \rightarrow 2C_2H_5OH + 2CO_2$

Sugar cane, wheat, forest waste

Cellulase

Amylase

79°C (lower than water's 100°C)

10% ethanol, 90% petrol

Ethanol: 46 kJ/g, Petrol: 48 kJ/g
