Abstract
We developed iron-oxide catalysts for producing petroleum-related chemicals from inedible biomass wastes containing water by oxidative cracking. These catalysts composed basically of iron-oxide and zirconia. The usefulness of the catalysts was examined by the reactions of several inedible biomass wastes, such as palm waste, livestock excreta, fermentation residue, raw glycerin, raw bioethanol and lignin. It was found that ketones, mainly acetone, were produced from palm waste, livestock excreta, fermentation residue and raw bioethanol at high yields. Phenol was obtained from palm waste. In the case of raw glycerin, even if high contents of alkali, allyl-alcohol, propene and acetone were successfully produced. Furthermore, phenols could be recovered from lignin.
