炭-催化剂性能对8#滤毒罐防毒性能的影响分析

8~#滤毒罐是专门防护硫化氢气体的防护器材,所装填的药层是炭—催化剂,因此,炭—催化剂性能的优劣决定着滤毒罐防毒时间的长短。也就是说,炭—催化剂性能好,所装填的8~#罐的防毒时间就长;炭—催化剂的性能差,8~#罐的防毒时间就短。 通常,8~#滤毒罐是靠化学吸着作用达到防毒的目的。化学吸着是由吸附质与吸附剂分子之间以类似化学链的力相吸发生的,吸附质与吸附剂形成表面化合物,吸附热较高,有选择性,通常不可逆,炭—催化剂借助于

OH radicals generated by DC corona discharge for improving the pulsed discharge desulfuration efficiency

Positive DC corona discharge is formed with needle-plate electrode configuration, in which the water vapor is ejected though the needle points. The purpose is to increase the numbers of the water-based radicals, ionize the water molecule and improve the desulfuration efficiency of pulsed corona reactor. The water ions were determined by four stages molecular beam mass spectrometer and diagnose the water-based radicals by emission spectrograph. A conclusion on formation of ions and radicals with DC corona discharges can be drawn.     

Kinetics study on catalytic wet air oxidation of phenol by several metal oxide catalysts

Four metal oxide catalysts composed of copper (Cu), stannum (Sn), copper-stannum (Cu-Sn) and copper-cerium(Cu-Ce) respectively were prepared by the co-impregnation method, and γ-alumina(γ-Al2O3 ) is selected as support. A first-order kinetics model was established to study the catalytic wet air oxidation of phenol at different temperature when these catalysts were used. The model simulations are good agreement with present experimental data. Results showed that the reaction rate constants can be significantly increased when catalysts were used, and the catalyst of 6% Cu-10% Ce/γ-Al2 O3 showed the best catalytic activity. This is consistent witht he result of catalytic wet air oxidation of phenol and the COD removal can be arrived at 98.2% at temperature 210℃, oxygen partial pressure 3 MPa and reaction time 30 rain. The activation energies of each reaction with different catalysts are nearly equal, which is found to be about 42 kJ/mol and the reaction in this study is proved to be kinetics control.
