RESEARCHSeptember 22, 2008Process makes gas from biomassMix the right metals into watered-down sugars from grasses, wood and agricultural waste and you get an organic oil. Mix other catalysts into the oil and you get gasoline, diesel or jet fuel.The first step of the two-step process turns carbohydrates extracted from cellulosic biomass into a liquid hydrocarbon. The second step turns the precursor hydrocarbon into the desired fuel. The process is a more versatile alternative to producing ethanol from biomass because it can produce a range of fuels. Gasoline also packs about a third more energy than ethanol.
