The effects of temperature on polymerization rate of propyleno were determined with diethyl aluminum chloride catalyst system in both open and closed operation systems. The order and the rate constant of the reaction were determined. The energy of activation is calculated from the following eguations:

用封闭和开放体系测定了索尔维(Solvay)型催化剂-AlEt_2Cl体系丙烯聚合时温度对聚合速度的影响,测定了反应级数和速度常数,采用下式: E=2.303R log(K_2/K_1)[(T_1·T_2)/(T_2-T_1)] E=2.303R log(V_2/V_1)[(T_1·T_2)/(T_2-T_1)]分别求得了活化能。

This paper describes the development of two types of CCD MTI cancellers. One is a four channel parallel-operation system with sampling frequency of 2.1 MHz. In this system the .clocks between adjacent CCDs are alternated in lower frequency overlapping mode. The system is very suitable for narrow pulse radars. Tke other is a single channel two pulse canceller with sampling rate of 250kHz.This system can successfully be applied to wide pulse radars.

Active carbon catalysts loaded with some active components which are capable of producing iodine species to give more effective elimination and recovery of SO2 as H2SO4 from the flue gas have been developed. Effects of the process variables on catalytic activity and adsorption capacity were investigated. A 680 hours stability test run with certain measures provided for showed no apparent decline in catalytic activity.A pilot plant wih a four-tower shift operation system capable of treating 5000M3/hr flue gas from a coal fired power plant has been built and successfully operated. The results were in good agreement with the laboratory results.With a flue gas containing 3000-4000ppm of SO2,at an inlet temperature of 55-65℃, and with a space velocity of 400-500hr-1, a duration of 12-15 hrs for maintaining a SO2 conversion greater than 90% was found during a 18-20 hours adsorption period. The adsorption capacity was 12-14 g SO2/ 100g catalyst. A five-stage successive washing in the regeneration operation raised the concentration of the product H2SO4 to 20%(wt.). A stability test run has been carried out for more than 1800 hours, no apparent deactivation of the catalyst was observed.

评选出一种含某些活性组分的活性炭催化剂,运转时能提供参与反应的碘,使其脱SO_2性能远超过原炭。考察了各种反应条件对催化活性和吸附量的影响。还进行了680小时的催化剂稳定性试验。又建立了有4个塔切换操作的中间工厂,每小时处理燃煤烟气5000米~3,运转结果与实验室完全一致。在烟气中SO_2为3000—4000ppm,烟温为55—65℃,空速为400—500小时~(-1),吸附时间18—20小时的条件下,其中SO_2转化率在90%以上约占12—15小时。吸附量可达12—14克SO_2/100克催化剂。经过五级洗涤再生,副产硫酸浓度可达20%。1800小时稳定性试验,表明催化剂的活性基本稳定。
