“Green Gasoline”: Like Gasoline, But Made from Cellulose : TreeHugger
Though they may share many of the same compounds and properties, “green gasoline,” the creation of UMass chemical engineer George Huber, differs from regular gasoline in one important respect: it can be produced from biomass sources. And, unlike the various forms of ethanol that have been bandied around, green gasoline can take advantage of the existing gas infrastructure and be pumped into cars as is.

To produce this biofuel variant, Huber and his students heated plant cellulose in the presence of solid catalysts and then rapidly cooled the products – leaving behind a liquid that already contained many of the compounds typically found in gasoline, such as naphthalene and toluene. The whole process takes less than 2 minutes to accomplish and needs only moderate heat; the final liquid can be further refined or immediately used as an alternative to a high octane gas blend.

I guess the big questions are: what is the cost of the catalysts and are they a reusable or expendable agent? This sounds wonderful, but if it’s this simple why is it gonna take them 5 years at a minimum to get it to the pumps? I realize that scaling up is gonna make a difference and building the infrastructure will take a while but still sounds like there are things about this process or the resultant fuel that they don’t bring up.

That said I hope this works out and results in a viable fuel making process using biomass. 😎

Interesting concept and one I rather like.
