METHOD FOR CONVERSION OF AROMATIC HYDROCARBONS |
| 摘要 |
A method of converting hydrocarbons requires contacting a hydrocarbon stream containing alkylated aromatic hydrocarbons with a catalyst of a phosphorus-containing pentasil zeolite in a reactor. The phosphorus-containing pentasil zeolite having a phosphorus content of 7.5% or less by weight of zeolite, a pore volume of at least 0.2 ml/g, and a 27Al MAS NMR spectrum characterized by a peak at or near 50 ppm that is greater than any other peak in said spectrum. A benzene-enriched output stream is recovered from the reactor. |

1. A method of converting hydrocarbons comprising:
a. contacting a hydrocarbon stream containing alkylated aromatic hydrocarbons with a catalyst of a first phosphorus-containing pentasil zeolite in a reactor, said phosphorus-containing pentasil zeolite having:
i. a phosphorus content of 7.5% or less by weight of zeolite;ii. a pore volume of at least 0.2 ml/g; andiii. a 27Al MAS NMR spectrum characterized by a peak at or near 50 ppm that is greater than any other peak in said spectrum; and b. recovering a benzene-enriched output stream from the reactor. |
