Treatment of straw pulp's black liquor and organic waste water of high COD value by wet air catalytic oxidation possesses the following advantages: the lower consumption of energy, more compact cquiqment and extensive application. Comparing with non-catalytically wet air oxidation method, the required reaction temperature and operating pressure in WACO are lowered effectively by catalytic action, so the investment funds and oporating cost are reduced. In this work, the catalyst and reaction condition have been investigated. The experiments arc taken place in both batch process and continuous process, in which a 0.51 autoclave and a 0.5~2 1/h flow reactor are used respectively. It is found that a selected Cu catalyst signed Cu (Ⅱ) is the best one in the homogeneous catalysts searched. The reaction tcmpereture is the main parameter influcucing COD-dccrease and better results were already obtained above 220℃. when O_2/COD>1.4, the influence of O_2/COD on reaction result is insignificant. At 250℃, 60 kg/cm~2, LHSV 0.62 hr~(-1), O_2/COD>1.4. Cu (Ⅱ) 50 ppm, the decrease of COD is about 90%.

The trial application of catalyst B-02 for oxidative dehydrogenation of butene into butadiene has been carried out on a commercial plant of 10000 t/a capacity for 5 137 h of continuous operation. The inlet temperatures of the first and second stages are 33C-360 ℃,and 335-370℃, the space velocities of butene in the first and second stages of reactors are 180-190 h-1 and 210-250 h-1, and the total oxygen to butene and the water to butene ratios are 0.70-0.72 and 12-13, respectively. Under these operating conditions, the butadiene yield, butadiene selectivity, butene consumption,and catalyst consumption are 61.0-64.0%,89.0-91.6%,1.183 t/t butadiene, and 1.45 kg/t butadiene, respectively. This result has basically reached the level of the same catalyst on pilot plant. Compared with the original six-components catalyst, the cost of butadiene is reduced by 271.60 yuan/t butadiene, the butadiene production is increased by 743.8 t in total, the effluent for producing every ton of butadiene is reduced to 1/25, and the effluent can be discharged after being simply treated,thus basically eliminated the environment pollution.
