Abstract:
A method for forming para-xylene (PX) from fuel syngas comprising reacting the fuel syngas comprising methane and water on a once-through basis with a feed including an aromatic compound selected from the group consisting of toluene, benzene and mixtures thereof, in the presence of a catalytic reaction system which converts greater than 15 wt. % of the aromatic compound to a mixture of xylenes, where PX comprises at least 48 wt. % of the mixture of xylenes, and where the catalytic reaction system comprises:a first component selected from the group consisting of metals and metal oxides, where the metal element is selected from the group consisting of the Groups 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16 of the Periodic Table of Elements (new IUPAC notation); and a second component selected from the group consisting of crystalline or amorphous aluminosilicates having one-dimensional channel structure, para-alkyl selectivated amorphous aluminosilicates, para-alkyl selectivated substituted aluminosilicates, crystalline or amorphous substituted silicates having one-dimensional channel structure, para-alkyl selectivated substituted silicates, crystalline or amorphous aluminophosphates, crystalline or amorphous substituted aluminophosphates, para-alkyl selectivated crystalline or amorphous aluminophosphates, para-alkyl selectivated zeolite-bound zeolite, para-alkyl selectivated substituted aluminophosphates, and mixtures thereof.
