Zeolite Beta as a catalyst for alkylation of benzene with ethylene: a deactivation study

摘要

Zeolite Beta is applied successfully as a catalyst for the alkylation of benzene (B) with ethylene (ET) to ethylbenzene (EB). Reaction conditions modify the performances and the lifetime of the catalysts. Under liquid phase operation, zeolite Beta whows any significant deactivation. However at lower reaction temperatures a decrease in both firee sites and void channel volume s registeres, due to carbonaceous compounds deposition.
