Process makes gas from biomass
Mix 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.
