Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. The gasoline-range alcohols can be high-octane gasoline additives.
At last month’s World Renewable Energy Forum 2012 in Denver, Colorado, researchers from the US National Renewable Energy Laboratory presented papers on two different approaches to upgrade pyrolysis oils to hydrocarbon fuels or fuel intermediates.

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil.
When crude oil comes into a refinery, it is first passed into a distillation process, which separates the crude oil into its different fractions by boiling range. Naphtha refers to the light fraction produced by distillation that is roughly in the gasoline boiling range of ~30 °C to ~200 °C. —Chang et al.
Costs ranged from a low of 0.3% of GDP in China to nearly 6% of GDP in Saudi Arabia, where, despite two cycles of price hikes, 60% of the cost of energy products and services continued to be borne by the state. 5 consumer of oil,” Krane said. Subsidies remained sticky outside the G20 as well.
The increase is largely driven due to a combination of low-cost natural gas and sustained higher prices for gasoline and diesel in many countries, Navigant suggests. The differential in the cost of the fuels determines the payback on this additional equipment (currently between 2.5 and 6 years, depending on the vehicle).
