Ccramic honcycomb catalytic ozonation (CH catazonc) and activated carboncatalytic ozonation (carbozone) were proved to be efficient on the removal ofcertain micropollutants in bench experiments，while the operation character_ ofcarbozone-GAC processes remains to be explored, so in this study， the operatingcharacteristics of CH catazone,carbozone and their following granular activatedcarbon(GAC) filtration were investigated by pilot experiments.yrdcarbon
Under the -study 1condition, the gas-liquid mass transfer efficieney. of-CHcontactor was slightly lower than that of ozone contactor unless gas-liquid ratio waslarger than 0.15.At a flow rate of 0.1 m'/h, the gas holdup (a,) of ozone and CHcontactor was 0.19%and 0.15% respectively,thus the bubble size was relativelylarger in CH contactor，which was adverse on gas-liquid mass transfer. Calculatedby liquid pulse tracer input test, the Pe number of ozone and CH contactor was 3.14and 5.25 respectively，thus the portion of plug flow was relatively larger in CHcontactor，which was positive on gas-liquid mass transfer. The increase of gas flowrate may promote gas-liquid mass transfer more obviously in CH contactor.activated charcoal powder wholesale
Usually, the fuel type NOx generated in pulverized coal combustion accounts for 80%~90% of the total NOx.Ding Xinda activated carbon performance indicators using the national standard method after grinding the measured value is larger than the ungrinded value, in which the iodine value of the powder test is 50~130 mg/g larger than the particle test value: the phenol value of the powder test is 10~-40 mg/g larger than the particle test value, and the correlation coefficient between the powder test value and the particle test value is not high.
Heavy machinery is a variety of machinery industry, complex equipment structure, large demand, wide use of machinery industry.
