Selective toluene disproportionation process (STDP) with ex situ selectivated zeolite catalyst |
摘要 |
A process for shape selective hydrocarbon conversion that involves contacting a hydrocarbon feedsteam, including toluene, under conversion conditions with a catalytic molecular sieve which has been modified by being ex situ selectivated with a silicon compound. The ex situ selectivation involves exposing the molecular sieve to at least two silicon impregnation sequences, each sequence comprising an impregnation with a silicon compound followed by calcination. The modified catalyst used in the process may also be steamed. Optionally, the modified catalyst may be trim-selectivated.
