Feedstock
Oil-seed crops (oil seed rape, sunflower oil, palm oil, soybean oil)
Oil seed rape is common in what country
U.K.
How is the fuel synthesized from oil seeds?
oil seeds are mixed w/ two industrially sourced chemicals, methanol and a strong base catalyst (NaOH or KOH) - this causes the formation of fatty acids and glycerol - fatty acids react further to produce biodiesel
Transport Biofuels: biodiesel and bioethanol
Biodiesel cannot be used on its own in traditional internal combustion engines Bioethanol can be used on its own or in a blend of biofuels
Biofuels make up what percentage of petroleum blend in U.K.?
5%
Most biodiesel production is in?
Europe
What countries started using biodiesel
Tanzania & India (trains coming between Mumbai and Delhi use biodiesel that contains 15% biodeisel from jatropha)
Jatropha
can tolerate drought conditions and grows on poor land unsuitable for agriculture; does not compete w/ food production
Biodiesel
liquid fuel produced from renewbale sources such as new and used vegetable oils, animal fats, and is a clearer-burning replacement for petroleum-based diesel fuel
Most common blend of biodiesel
B20 (20% biodiesel and 80% (Petroleum diesel)
Quick sequence from waste or plant oil to biodiesel
Waste or plant oil - heated - processor (add NaOh or KOH + menthanol) - unwashed biodiesel and glycerol - remove glycerol layer - unwashed biodiesel - wash and allow to dry - fill fuel tank
