AbstractWyoming bentonite, exchanged with cations of high charge density, is an efficient and selective catalyst for the production of ethyl acetate, in a single step, from ethylene and acetic acid. The reaction occurs in the interlamellar space of the clay where it is proposed that strong Brönsted acid sites on the clay coupled with highly polarized intercalated reactants produce a reaction which is otherwise difficult to carry out.

Catalytic hot gas filtration (CHGF) is used to precondition biomass derived fast pyrolysis (FP) vapors by physically removing reactive char and alkali particulates and chemically converting reactive oxygenates to species that are more easily upgraded during subsequent catalytic fast pyrolysis (CFP). Carboxylic acids, such as acetic acid and propionic acid, form during biomass fast pyrolysis and are recalcitrant to downstream catalytic vapor upgrading. This work developed and evaluated catalysts that can convert these acids to more upgradeable ketones at the laboratory scale. Selective catalytic conversion of these reactive oxygenates to more easily upgraded compounds can enhance bio-refinery processing economics through catalyst preservation by reduced coking from acid cracking, by preserving carbon efficiency, and through process intensification by coupling particulate removal with partial upgrading. Two metal-doped molybdenum carbide (Mo2C) supported catalyst beads were synthesized and evaluated and their performance compared with an undoped Mo2C control catalyst beads. For laboratory scale acetic acid conversion, calcium doped Mo2C supported catalyst beads produced the highest yield of acetone at ~96% at 450 °C among undoped and Ca or Ni doped catalysts.

Selective Catalyst

Ir/AlO(OH)/Fe3O4 catalyst has been prepared and applied for the hydrogenation of p-choronitrobenzene (p-CNB) to p-chloroaniline (p-CAN) at 35 °C and balloon hydrogen pressure in ethanol/water mixture. The experiment results indicated that the catalyst Ir/AlO(OH)/Fe3O4 showed excellent catalytic properties for the hydrogenation of p-CNB to p-CAN. A complete conversion of p-CNB was achieved with a selectivity of 97.2 % to p-CAN. The catalyst was quite stable and can be recycled at least seven times without loss of any activity. Moreover, the magnetic property of the catalyst facilated the separation of the used catalyst from the reaction system without filtration.
