    Abstract: Spent zeolite equilibrium catalyst from the fluidized catalytic cracker has a useful function as an adsorbent for jet fuel. Redirecting such spent catalyst saves costs for refinery operations in two ways. The first is by avoiding the costs for disposing of such catalyst as hazardous waste. The second is to reduce the cost of procuring sorbent for the jet fuel decontamination process. Since zeolite is primarily silica and conventional sorbents are also silica, zeolite catalysts are chemically similar. And the equilibrium catalyst may be regenerated in the FCC after its becomes saturated with jet fuel contaminants and re-used.

    Abstract: Carbohydrates as derived from plant biomass can be converted into mono-alcohols, diols, and/or bi-functional alcohols or into carboxylic acid derivatives. By catalytic transesterification of such carbohydrate derivatives, ester-type diesel-fuel blendstock components may be produced. More specifically, alkyl levulinates are catalytically trans-esterified with hydroxyl-functionalized compounds where both the alcohols and the alkyl levulinates are derived from biomass carbohydrates. Esters produced in this way show physicochemical characteristics that make them suitable for use as diesel fuel blendstock.
