Process and apparatus for the conversion of hydrocarbons
A hydrocarbon conversion process is described. The process includes contacting in a reactor an inert gas with one or more catalyst compositions suitable for methylation of toluene and hydrogenation of phenol; contacting a reducing agent with the one or more catalyst compositions under conditions suitable for reducing metal oxide content of the catalyst composition; contacting at least part of toluene and/or benzene-containing with a oxygenate in the presence of the one or more catalyst compositions and under conditions effective to convert toluene to xylenes and produce a reactor effluent stream comprising para-xylene and having a lower concentration of phenol than the toluene-containing stream; separating at least one para-xylene-enriched stream from the reactor effluent stream; and separating from the at least one para-xylene enriched stream at least one toluene-enriched stream and at least one para-xylene-product stream. An apparatus for carrying out such a process is also described.

SUPPORTED INTERMETALLIC COMPOUNDS AND USE AS CATALYST
A composition comprising a ternary intermetallic compound X.sub.2YZ, wherein X, Y, and Z are different from one another; X being selected from the group consisting of Mn, Fe, Co, Ni, Cu, and Pd; Y being selected from the group consisting of Cr, Co, and Ni; and Z being selected from the group consisting of Al, Si, Ga, Ge, In, Sn, Zn, and Sb; wherein the ternary intermetallic compound is supported on a porous oxidic support material. The composition may be prepared by providing a liquid mixture of sources of X, Y, and Z, and the porous oxidic support material, removing the liquid and heating the resulting mixture in a reducing atmosphere. The composition is useful as catalyst.

METHOD FOR DECREASING THE CONCENTRATION OF A METAL IN A MONOMER COMPOSITION COMPRISING BIS(BENZOYL)BENZENE
Disclosed are methods of decreasing the concentration of a metal in a monomer composition including a bis(benzoyl)benzene, bis(benzoyl)benzene monomer compositions having a low total metal concentration, di-ketone polymers made from low metal bis(benzoyl)benzene monomers, and polymer compositions and shaped articles including the di-ketone polymers. It was surprisingly found that di-ketone polymers made by nucleophilic substitution of low metal bis(benzoyl)benzene monomers exhibit greater crystallinity, as compared with di-ketone polymers made with conventional monomers.
