Katalysator und Verfahren zur Herstellung von monozyklischen Aromaten

摘要

The present invention provides a catalyst to produce a monocyclic aromatic hydrocarbon from hydrocarbons, which comprises a zeolite containing substantially no proton and having an intermediate pore diameter, a molar ratio of SiO 2 to Al 2 O 3 of at least 20 and silver, and which further comprises at least one metal belonging to Group IIb, IIIb and Group VIII of the Periodic Table. Further, the present invention provides a method to catalytically convert hydrocarbons by using the above catalyst. By means of the present invention, there can be provided a stable catalyst for conversion of hydrocarbons, which is capable of obtaining monocyclic aromatic hydrocarbons with good balance and a high yield, and which is hardly deteriorated by steam having a high temperature.
