Abstract
This present disclosure relates to a catalytic process for upgrading crude and/or refined fusel oil mixtures to higher value renewable 2-methyl-2-butene, via novel doped alumina catalysts. It was found that passing a vaporized stream of crude and/or refined fusel oils over doped alumina catalysts provides renewable 2-methyl-2-butene in high yields in a single step. Subsequent downstream purification of the reactor effluent results in a renewable 2-methyl-2-butene at competitive price and quality to fossil fuel derived 2-methyl-2-butene.
