“…Among these chemicals, allyl alcohol can be more useful and 5 On the contrary, we have developed zirconia-iron oxide catalyst, ZrO 2 -FeO X , for the catalytic conversion of biomass resources. We have succeeded in producing phenol and ketones from tar derived from wood biomass [17][18][19][20], sewage sludge [21], and fermentation residue [22] over ZrO 2 -FeO X , in which ZrO 2 loaded on FeO X contributes to the high catalytic performance and stability. Since ZrO 2 -FeO X works effectively on the organic compounds 5 having hydroxyl and carboxyl groups, the catalyst is expected to be applicable to the catalytic conversion of glycerol into useful chemicals.…”

The catalytic conversion of glycerol was performed with iron oxide-based catalysts for production of allyl alcohol using a fixed-bed flow reactor at 623 K under atmospheric pressure.The glycerol dehydration proceeds on acid sites of catalysts while the allyl alcohol production is assumed to be catalyzed by non-acidic sites of catalysts through a hydrogen transfer mechanism.Different alkali metals, including Na, K, Rb, and Cs were supported on ZrO 2 -FeO X and all of them gave impressively higher allyl alcohol yield and suppressed glycerol dehydration due to the reduced catalyst acidic property. K-supported ZrO 2 -FeO X (K/ZrO 2 -FeO X ) was chosen for further studies, and allyl alcohol yield remarkably increased up to 27 mol%-C at the K content of 3-5 mol%. Since no external hydrogen gas is supplied to the system, the hydrogen transfer mechanism should take place between the reaction of glycerol and either hydrogen atoms derived from formic acid forming during the reaction, or active hydrogen species produced from the decomposition of H 2 O by ZrO 2 .Addition of Al 2 O 3 to K/ZrO 2 -FeO X (K/Al 2 O 3 -ZrO 2 -FeO X ) was examined in order to improve structure stability during the glycerol conversion. Al 2 O 3 addition to the catalyst was effective to achieve higher structure stability, leading to high glycerol conversion with stable allyl alcohol yield of above 25 mol%-C. Moreover, K/Al 2 O 3 -ZrO 2 -FeO X can be applicable to the conversion of crude glycerol which is the waste solution obtained from biodiesel production.3

“…Figure 14 shows the desorption rate of hydrogen generated by the decomposition of steam when the catalysts were heated after the pre-adsorption of steam on the catalysts. The catalyst supporting zirconia exhibited higher steam decomposition activity, even at lower temperatures, producing hydrogen (Masuda et al, 2001). Simultaneously, active oxygen species were generated from steam.…”

“…The conversion of black water into useful chemicals requires catalysts having the following properties: a strong ability to decompose the hydrocarbons in the black water, stable activity in the presence of water, and resistance to the deposition of impurities contained in the black water. Zirconia-supporting iron oxide catalysts are effective for the decomposition of oil palm waste (Masuda et al, 2001) and petroleum residual oil (Fumoto et al, 2004) in a steam atmosphere. Oil palm waste can be converted to a mixture containing phenol, acetone, and butanone using the catalyst.…”

This study investigated the transfer of oxygen and hydrogen species from steam to product during the catalytic cracking of heavy oil with iron oxide-based catalysts containing zirconia and alumina. Light oil and carbon dioxide were produced in the catalytic oxidative cracking of petroleum residual oil in the presence of steam. The alkene/alkane ratio of light aliphatic hydrocarbons decreased and carbon dioxide yield increased with higher flow rate ratio of steam to feedstock. The steam catalytic cracking of dodecylbenzene as a model compound of heavy oil showed lower alkene/alkane ratio and generation of a small amount of oxygen-containing compounds. The oxygen species derived from steam reacted with heavy oil and were transferred to carbon dioxide and a small amount of oxygen-containing compounds, producing hydrogen species from the steam. The hydrogen species were transferred to light hydrocarbons, thus suppressing alkene generation. The alkene/alkane ratio decreased with higher supporting zirconia content in the catalyst because zirconia promotes hydrogen generation from steam.
