At present, the industrial route for the production of cyclohexanone cyclohexane oxidation, there are two First cyclohexane catalytic oxidation, and the other is non-catalytic oxidation of The traditional process of production of cyclohexyl alcohol and cyclohexanone (KA oil), the process is complex and serious Therefore, to find a new energy to maximize cyclohexane conversion rate and the selectivity of the alcohol and ketone oxidation method has great Metal porphyrin catalysts to improve the role of traditional crafts shortcomings, showing high activity and selectivity is the main object of study of the catalytic oxidation of The conversion rate of cyclohexane, cyclohexyl alcohol selectivity of cyclohexanone as the indexes were tetraphenylporphyrin copper (TPPCu), four (m-methylphenyl) porphyrin copper (Tm-MPPCu) (3,4 - dimethylphenyl) porphyrin copper (TDMPPCu) and other three metal porphyrin catalyzed oxidation of cyclohexane synthesis of cyclohexyl alcohol and cyclohexanone experiments, the purpose is to explore the tetraphenylporphyrin copper even methyl substituents at the benzene ring, the number of methyl substituted biomimetic catalytic oxidation of cyclohexane The experimental results show that: (1) within the scope of this experimental study, with methyl substituents on the benzene ring of the tetraphenylporphyrin copper, and its catalytic performance has improved, methyl substituted with a base number is more catalytic properties to improve more; (2) three metalloporphyrins have to study indicators of conditions, the optimum catalyst for is TDMPPC Suitable reaction conditions: the pressure 0MPa, air flow 10-12m3 / h, the catalyst concentration of 4 × 10-6g / g conditions, the optimum reaction temperature of 150 ° C, the reaction time was Under these conditions, the cyclohexane conversion rate of 23% of alcohol and ketone selectivity of 1%Keywords: cyclohexane; Metalloporphyrins; catalytic oxidation; methyl substituents the number of
高效的重金属去除聚合物纳米保湿由铁(3):行为和XPS研究氧化物 文摘:本研究开发了一种聚合物混合吸着剂(HFO-001)为高效的重金属去除(如铅(2)、Cd、铜(II),(2)]不可逆转的浸渍水合氧化(铁(III)在cation-exchange HFO)粒子(R-SO3Na D-001树脂),这种现象的潜在机制的基础上揭示x射线光电子能谱(XPS)的研究。HFO-001结合了出色的处理,和摩擦阻力流量特性,传统的cation-exchange树脂与特定的关系入手,对重金属HFOs阳离子。D-001相比,吸附选择性的HFO-001对铅(II)、铜(二)、(2)Cd大大提高从Ca(II)中更大的浓度。结果表明,柱吸附能力的工作是4-6 HFO-001 D-001倍以上三方面的重金属去除从模拟电镀水(pH ~ 0)。同样,HFO-001尤为有效杀灭多种微量铅(II)和Cd(2)从模拟自然水域达到饮用水标准,以治疗量高于D-001数量级。性能优越的HFO-001归因于Donnan膜效应所举办D-001以及纳米粒子交互作用的特殊HFO浸渍对重金属阳离子作为进一步证实,由XPS研究吸附铅。更有吸引力,疲惫的HFO-001串珠可以有效地解决由HCl-NaCl再生(pH值(3),没有任何有意义的能力的重复使用的损失。 1。简介:重金属注入受纳水体环境问题仍然是重要的,现在正在日益规范作为新的法规限制金属废水推进亿欧元(合ppb),甚至更低(美国EPA,2004年的水平,中国2008年美国环保署)。在现有技术、碱性降水重金属去除历来是首选的技术会议,(ppm)管理水平为微量铅(如第(二)、(二)、Cd等。]在direct-discharge废水点源,然而,这技术通常是限于≥污水浓度百万分之一的有限溶解无定形的金属氢氧化物阶段和效率低下的商业固液分离装置(代尔等,1998年,2003年)。离子交换树脂,利用strong-acid cation-exchange是另一个高效的技术,为有效去除工业废水中重金属的(Dabrowski等,2004,康等,2004;Kurniawan等,2006)或污染地下水(Vilensky等,2002;Dabrowski等,2004年)。然而,一个简单的交换过程中只被静电相互和非特异性为重金属去除(Demirbas等,2005;Carmona等,2008年)。

Modern in power system, electrical equipment, and numerous different components, easy operation complex various forms of electrical fault, so we must take measures to protect the relay to make the system more stable This thesis is to 110 kv power to relay protection, research and This paper firstly based on the characteristics of power generators and transformers parameter setting calculation, through the calculation results identify CT/PT At the same time, this may appear on the various forms of short-circuit current exhaustive According to thisThe design parameters of short-circuit current, adopted a phase spacing protection and the zero sequence current protection relay protection measures of But because of relay protection device may be due to the defects in the misoperation, therefore also adopts the design of automatic reclosing technology, through the automatic reclosing device can reduce the misoperation, make the whole power system can be more stable Key words: relay protection, Phase spacing protection, The zero sequence relay protection, Automatic reclosing
Now, with the continuous development of international economic exchanges, the pace of economic globalization and China's economy in further accelerate as an important pillar of the world economy merge with the world economy, and further enhance the trend in our country foreign trade enterprises in China's entrance into WTO and rapid development and But recently, the global economy in American house under the influence of the subprime crisis, is experiencing a financial Many Chinese foreign trade import and export enterprises are facing bankruptcy and mergers even downsizing, foreign trade enterprise's survival and development of the unprecedented Whether from a historical perspective, or reality of foreign trade enterprise internal management mode and adjustment actively seek survival and development the new breakthrough has important theoretical and practical This paper firstly under the financial crisis of international economic environment and history of the case, then summarizes briefly to our country foreign trade enterprise in today's financial crisis and the dilemma under pressure are discussed, and finally put forward our country foreign trade enterprise management method and seek new export enterprise's survival and development 不错吧~!
There are a large number of power equipment in modern power system,among which each compponent operate in a complex way Because of the above mentioned element,various kinds of electrical fault can easily occured ,then relay protection measures need to be taken so as to ensure the smooth operation of the whole This paper is focus on the protection and designation on relay protection measures of 110 KV The first part of the paper is to tuning calculate the parameter of generator and transformer in accordance with the characteristics of the grid Through the result of this calculation ,the model of CT/PT can be At the same time ,the paper also have some detailed calculation on various kinds of possible short According to this parameter of the short-circuit current ,two kinds of relay protection ,that is phase distance protection and zero sequence current protection are employed in this designation But because the drawbacks of relay protection settings can make some wrong operation ,automatic reclosing technology has been used in this designation ,which minimize the malfunction ,so as to ensure the stead operation of the whole power system
Today, international economic exchanges with the continuous development of economic globalization to further accelerate the pace of China's economy the world economy as an important pillar of economic integration with the world to further strengthen the trend, China's foreign trade enterprises are rapidly after entering the WTO development and But recently, the global economy in the US housing loan crisis times, the serious face of a financial crisis brought about by Many import and export enterprises in China are faced with layoffs, mergers or even bankruptcy of the status quo, the survival of foreign trade enterprises and the development of unprecedented Or whether it is realistic from a historical point of view, the adjustment of the internal management of foreign trade enterprises to actively seek new models and the survival and development are very important breakthrough in the theoretical and practical In this paper, under the first financial crisis of the international economic environment and a brief historical overview of the case, and then on China's foreign trade enterprises under the current financial crisis and pressure on the plight of an analysis of the end of China's foreign trade enterprises to optimize their management methods and to seek survival and development of new export business
