Watts wrong with butanol?
While significantly better than ethanol (except in octane rating) I don't see it as good as diesel. Shell's Pearl GTL plant also produces Naphtha with is part of the feedstock to gasoline.
I haven't seen anyone successfully make the economics work for Butanol. Shell's process in now in commercial use at their second facility. I expect we will soon see more of them.
If nothing else, it is an alcohol, and is hydrophilic.
