Shape selective hydrocarbon conversions over modified catalyst |
摘要 |
A process for shape selective hydrocarbon conversion involves contacting a hydrocarbon feedstream under conversion conditions with a catalytic molecular sieve which has been modified by treatment with an amino silane polymer while molecular sieve acid sites are protected. When the process is toluene disproportionation, a toluene feedstream may also contain a second silicon source which is a high pxylene selectivating agent. The invention also includes the modification method and the shape selective catalyst which results from the modification.
