Abstract CoAPO-11 zeolite was synthesized by the hydrothermal method, and the isomerization properties of n-butene over Pd/CoAPO-11were investigated. The results showed that the yield of isobutene increased at first and then decreased slowly with the increase of temperature, and the optimum yield was obtained at 400 ℃. Compared with traditional commercial support γ-Al2O3 supported, CoAPO-11 supported Pd exhibited better performance of n-butene isomerization. During the 200 h stability pilot test, Pd/CoAPO-11 catalyst showed better long-time stability, and the selectivity and yield of isobutene were about 86% and 39%, respectively.
