A Ni Mg β catalyst consisted of a non noble metal active component carried on β zeolite for n pentane isomerization was prepared in the laboratory. The reaction performance was investigated on a pressurized micro reactor with chromatography. The evaluation result showed that at a temperature of 295 ℃, a pressure of 2.8 MPa, a WHSV of 1.5 h -1 and a hydrogen to n pentane ratio of 4, the conversion, selectivity, i pentane yield and liquid yield were 68.19%, 94.73%, 64.59% and 96.69% respectively. The conversion was 93.4% of the equilibrium conversion at the said reaction temperature.
