摘要： Catalyst compositions and processes for making and using same. The catalyst composition can include catalyst particles. The catalyst particles can include 0.001 wt % to 6 wt % of Pt and up to 10 wt % of a promoter that can include Sn, Cu, Au, Ag, Ga, or a combination thereof, or a mixture thereof disposed on a support. The support can include at least 0.5 wt % of a Group 2 element. All weight percent values are based on the weight of the support. The catalyst particles can have a median particle size in a range from 10 μm to 500 pm. The catalyst particles can have an apparent loose bulk density in a range from 0.3 g/cm3 to 2 g/cm3, as measured according to ASTM D7481-18 modified with a 10, 25, or 50 mL graduated cylinder instead of a 100 or 250 mL graduated cylinder.

摘要： Disclosed are processes for conversion of a feedstock comprising C8+ aromatic hydrocarbons to lighter aromatic products in which the feedstock and optionally hydrogen are contacted in the presence of a first and a second catalyst composition under conversion conditions effective to produce said lighter aromatic products comprising benzene, toluene and xylene. In the process, the C8+ aromatic hydrocarbons are dealkylated to form C6-C7 aromatic hydrocarbon and the C2+ olefins formed are saturated. The remaining C8+ aromatic hydrocarbons are transalkylated with the C6-C7 aromatic hydrocarbon. The first and second catalyst compositions each comprise a zeolite, a first metal, and optionally a second metal, and are treated with a source of sulfur and/or a source of steam.
