    Abstract: An object of the present invention is mainly to provide a catalyst with which an α,β-unsaturated aldehyde and/or an α,β-unsaturated carboxylic acid can be produced with a high selectivity. Provided is a catalyst used for producing, by an oxidation reaction of a hydrocarbon, a corresponding α,β-unsaturated aldehyde and/or α,β-unsaturated carboxylic acid, and the catalyst contains molybdenum, bismuth, and cobalt, and satisfies the following Formula (I-1): (x2−x1)/σ1≤1.5 (I-1) In Formula (I-1), x1, x2, and σ1 are values obtained by binarizing a reflected electron image of the catalyst, which is obtained using a scanning electron microscope (SEM) at an accelerating voltage of 15 kV, into black and white and subsequently performing an energy dispersive X-ray spectroscopy (EDS) analysis; x1 represents a bismuth concentration [% by mass] in black parts; x2 represents a bismuth concentration [% by mass] in white parts; and σ1 represents a standard deviation of the bismuth concentration in the black parts.

    Abstract: Process are disclosed for converting plastics, and especially thermoplastic oxygenated polymers, by hydrodeoxygenation (HDO) to hydrocarbons, such as aromatic hydrocarbons including benzene, toluene, ethylbenzene, and xylene isomers. These hydrocarbons may be recovered as chemicals and/or fuels, depending on the particular chemical structures of the starting materials, including the presence of oxygen in the polymer backbones. Advantageously, using a sufficiently active catalyst, only moderate conditions, such as in terms of hydrogen partial pressure, are required, in comparison to known hydrotreating processes. This leads to the formation, with fewer non-selective side reactions, of desired liquid hydrocarbons from substantially all carbon in the oxygenated polymer, as well as water from substantially all oxygen in the oxygenated polymer. In some cases, the liquid hydrocarbons obtained are platform chemicals that can be used for a number of specialized purposes. For example, they may be converted to monomers for regenerating the oxygenated polymer or otherwise for producing a different polymer.
