  gasoline
Study on reformulation of fluid catalytic cracking gasoline and increasing production of light olefins
      
The experimental results showed that FCC gasoline was obviously reformulated under appropriate reaction conditions.
      
The olefins (olefins with C atom number above 4) content of FCC gasoline was markedly reduced, and the aromatics content and octane number were increased.
      
The upgraded gasoline met the new standard of gasoline, and meanwhile, higher yields of light olefins were obtained.
      
Furthermore, higher reaction temperature, higher mass ratio of catalyst to oil, higher mass ratio of water to oil, and lower space velocity were found to be beneficial to FCC gasoline reformulation and light olefins production.

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....

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。

Recently,the world-wide attention has focused on the development and utilization of cellulosic materials as a source of energy,food and chemicals.Cellulosic materials are the most abundant crganic su- bstances on the earth;the total amount annually is approximately 100 billion tons,corresponding to 70kg per day for every one lived on the earth of 3.9 billion people.If 10% of these cellulosic materiaIs is used,500 billion gallons of liquid fuel will be obtained,equals to the amount expended per year in the United...

Recently,the world-wide attention has focused on the development and utilization of cellulosic materials as a source of energy,food and chemicals.Cellulosic materials are the most abundant crganic su- bstances on the earth;the total amount annually is approximately 100 billion tons,corresponding to 70kg per day for every one lived on the earth of 3.9 billion people.If 10% of these cellulosic materiaIs is used,500 billion gallons of liquid fuel will be obtained,equals to the amount expended per year in the United States by 5 times.Therefore, cellulose energy has attracted a great interest.Although,some of su- ch plants have been built in several countries,the level of present tech- niqe,however,has not rcached to Such an extent that a large-scale com- mercial plant can be easily developed.Therefore,extensive study is necessary. To utilize the annually replenishable resource,cellulose must be first converted into its structual sugar.In this review,recent advanc es of various hydrolys is methods,both developed and proposed,are discussed.

当今世界的注意力已经集注于纤维素物质作为燃料、食物、化学制品的开发和利用上面。纤维素物质是地球上数量最大的有机物质,每年的生成总量约有1000亿吨,按全球39亿人口计,人均每天就有70公斤。如果能利用这个总量的10%,每年就可以得到5000亿加仑的液体燃料,相当于美国年耗汽油量的5倍。正因如此,纤维素能源引起了人们的极大兴趣。但就目前的技术状态,这种能源的开发尚未达到大型工业化程度,许多技术问题有待进一步研究解决。为了利用年复一年可以复苏的资源,纤维素须首先降解。本文拟就各种水解技术的新进展进行讨论。

Unburned methanol and formaldehyde in exhaust emission of a methanolgasoline fuelled automobile were tested. A Gaussian-type model was used to simulate the methanol and formaldehyde dispersion in the air. The pollutant concentrations caused by the emisions from both point and line sources were calculated using this model. Concentration contour maps based on either measured or calculated data were plotted. The results obtained suggest no significant threat to ambient air quality from the application of methanol-gasoline...
