The preparation and field-test of the 778-type granular rare-earth catalyst for the treatment of auto exhaust gases have been studied. The alumina supporters with 4-7mm were impregnated with an aqueous solution of RE, Sr, Cu and Zr acetate mixture, and then were calcined in a muffle furnace in air at 800-1000℃ for several hours. In the fleld-test the catalysts were packed in a converter, and was connected to the exhaust end of a Shanghai-type bus which has a 6-cylinder gas engine of the CA-10B liberation...

The preparation and field-test of the 778-type granular rare-earth catalyst for the treatment of auto exhaust gases have been studied. The alumina supporters with 4-7mm were impregnated with an aqueous solution of RE, Sr, Cu and Zr acetate mixture, and then were calcined in a muffle furnace in air at 800-1000℃ for several hours. In the fleld-test the catalysts were packed in a converter, and was connected to the exhaust end of a Shanghai-type bus which has a 6-cylinder gas engine of the CA-10B liberation type. Analysis of the exhaust gases were made continuously during the test period. The removals of CO and HC were 79.2% and 78% respectively for the 53000km driving period. Besides, this converter can also reduce the noice by 3-7 decibel more than that in the exhaust muffler.

本文叙述了778型颗粒状汽车尾气净化稀土催化剂的研究和应用。将φ4—7毫米颗粒状氧化铝载体浸渍于RE、Sr、Cu、Zr的醋酸盐混合物水溶液,在800—1000℃空气气氛下于马弗炉中煅烧数小时。将制得的催化剂装入催化箱,与上海牌公共汽车(解放CA—10B六缸汽油发动机)的出口相连接。在车辆实际运行状况下,连续测定尾气浓度。当行驶53000公里时,CO、HC净化率分别为79.2%、78%。此外,本催化净化器还可比消音器减少噪音3—7分贝。

Some data of radiocarbon dating for geological and archaeological specimens with liquid scintillation counting in the end of the last year are presented in this paper.The instrument used with was made jointly by our university and the Institute of Atomic Nucleus Research in Shanghai.Its chief indices are as follows: the background is 2.3cpm the efficiency is 75%, the quality factor is above 2400, and dating maximum is about,50000 years.

An air quality simulation model (SJMM) for describing the photochemical smog pollution in that area has been developed in the light of a simplified photochemical kinetics mechanism. This model has been established on the basis of source emissions, meteorological conditions and topographical factors of Jingshan area in Shanghai.

An air quality simulation model (SJMM) for describing the photochemical smog pollution in that area has been developed in the light of a simplified photochemical kinetics mechanism. This model has been established on the basis of source emissions, meteorological conditions and topographical factors of Jingshan area in Shanghai. The validity of the chemical kinetics mechanism used has been demonstrated through comparative studies with UCR smog chamber data and results of Whitten's experiments using propylene. Calculated data by SJMM model are compared with the observed ones on Oct. 29, 1980. Finally, application of this model for predicting formation of photochemical smog in this area is discussed.

本工作以上海金山石油化工区为对象,探讨和建立了描述该地区光化学烟雾污染的大气质量模拟模式(简称SJMM),并与1980年10月29日实测数据进行了比较和分析。所用化学模式与国外烟雾箱数据及模式数据进行了对比。结果表明SJMM模式基本上能描述该地区的O_3、NO、NO_2的浓度分布和日变化情况。并利用模式预断了该地区出现光化学烟雾污染的可能性。
