Converting levulinic acid to olefins and aromatics (i.e. hydrocarbon fuels) in a single process step without external hydrogen gas
Summary: Iowa State University researchers have developed a new catalyst that effectively converts levulinic acid to butene in a single pot process at high conversion rates and with good selectivity towards butene. As butene is insoluble in the aqueous reaction and readily separates into a second phase, allowing unconverted levulinic acid to be rea...
