摘要
采用固载化骨架镍催化剂对双环戊二烯(DCPD)固定床连续催化加氢合成四氢双环戊二烯进行了研究。考察了温度、压力、氢油比和空速对DCPD加氢反应的影响,结果表明:固载化骨架镍催化剂对DCPD液相加氢合成桥式四氢双环戊二烯(endo-THDCPD)具有良好的催化作用。DCPD液相加氢反应过程与反应温度、压力、氢油体积比及空速有关,在反应温度为40℃,压力为2.5 MPa,氢油体积比为200,空速为2 h-1条件下,对催化剂进行了500 h长周期运转,DCPD的转化率达到95%以上;然后对催化剂进行了再生实验研究和XRD、SEM及BET表征,结果表明:催化剂活性、稳定性和再生性能良好。
The supported Raney Ni is used to hydrogenate DCPD in fix-bed reactor. The influences of temperature, pressure, ratio of hydrogen and oil and space velocity on the hydrogenation of DCPD are studied. The results show that the supported Raney nickel catalyst has effective catalytic activity for liquid-phase hydrogenation of DCPD to yield endo- tetrabydrodicyclopentadiene（endo-THDCPD）. The conversion of DCPD is greatly influenced by reaction temperature, eaction pressure, volume ratio of H2 to oil and liquid volumetric space velocity. Conversion of DCPD during whole evaluation process （500 hours） can reach over 95% in the following conditions ：2 MPa of the reaction pressure, 140℃ of reaction temperature,2 h^-1 of liquid volumetric space velocity and 200：1 of V（ H2 ）/V（oil）. XRD, SEM and BET are used to characterize the catalyst which is regenerated in certain conditions. As a result, the catalyst exhibits favorable properties of stability, regeneration and catalytic performance.
