- Abstract:
- DBD( Dielectrie Barrier Discharge ) plasma was used to sludy the hydrogenation reaction of benzeneby the CTp -2000K plasma power supply at atmospheric pressure. The discharge voltage, residence time andproportion of gas material were changed respectively to establish the optimized conditions. The optimized con-ditons were found to be discharge vollagel4 kV, residence time 12s, gas ratio of Vw/V,, =2: 1. The effect ofplasma - catalytic synergy on the raction was investigated. Compared with the result of non - existent catalyst,the percent conversion of benzene inereased from 7896 to greater than 90% , and the selectivity of cyclohexanecould reach 70% . The prepared catalyst was characterized by BH]and EMS ,respectively. The results indi-cate that the catalyst handled by plasma, the specific surface area increased from 13.72 m3· g-1 to 19.08 m3g-1, and the hole volume increased from 76.81 x10-3cm3·g-1 to 107.7 x 10-3cm3.g-1, respectively.SEM analysis shows the the surface grain size distribution on Ni/Si02 catalyst is uniform for 8 nm, the actionelement Ni of catalyst is up to 32% at outside surface
