| 英文摘要 | reaction performance, acidic and basic properties, as well as reduction properties of various supported molybdenum catalysts for the metathesis of ethylene and butylene-2 to propylene were investigated by tpr and nh3-tpd techniques in a flow-reactor. besides temperature, space velocity and pressure, the stability of a mo/(hbeta-al2o3) catalyst is strongly affected by the mo loading, the calcination temperature and the hydrothermal treatment conditions. a suitable molybdenum loading on hp-al2o3 is favorable to the stability of the catalyst that possesses suitable amount of acidity, which was determined by nh3-tpd measurements. the optimum preparation conditions of the mo/(hp-al2o3) catalyst are as follows: molybdenum content 3 wt.%, hydrothermal treatment and calcination at 550degreesc for 2 h and 700degreesc for 2 h, respectively. thus, the optimal catalyst of 3mo/(hbeta-al2o3), designated as 3mo/hp5502700, could keep a conversion of c4h8-2 at about 82% during 22h of reaction time-on-stream under the following conditions: n-2/c2h4 = 1.5, c2h4/c4h8-2 = 3/1, whsv(c2h4 + c4h8-2) = 1 h(-1), t = 120degreesc, and p = 1.0 mpa. in addition, a suitable pressure, such as 0.5-1.0 mpa, and a low temperature, such as 35degreesc, are beneficial for keeping the stability of the 3mo/hp5502700 catalyst.
