SiO〓 crystal transformation was improved by adding Na〓SO〓, alpha cristobalite but not tridymite was catalytic active support. C〓 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO〓. W-O in catalyst surface was not active species. The support combined with S, W, P show low activity and high C〓 selectivity.
Na〓SO〓的加入促进了SiO〓晶型的转化,α-方石英是催化活性载体成分,而鳞石英没有甲烷氧化偶联反应活性。W和P的加入改善了C〓烃的选择性,抑制了SiO〓的深度氧化特性;W-O物种不是催化活性物种;由S、W、P及SiO〓组成的载体反应活性较差,但选择性较好;同时S元素对C〓烃的选择性的贡献有限。

Dealcoholization temperature markedly influences the surface area and porosity of the resultant MAO-supports. When the support was pretreated at lower or higher temperature, the corresponding MAO-support shows very low surface area;2.XRD and IR analyses indicate that MAO has reacted with the residual ethanol in the supports, which is an important manner to get MAO fixed on the carrier. Morever, XPS analyse indicates that MAO can also be coordinated with MgCl_2, which is another way to get MAO fixed on the support;3.ICP and EDX analyses indicate that dealcoholization temperature not only determined the element content on the solid catalyst, but also influences the element distribution on the carrier;4.The activities of the supported phenoxy-imine catalysts and the properties of resultant polymers are strongly dependent on the dealcoholization temperature. The support (MSP-5) obtained by treating MgCl_2·2.56C_2H_5OH at 160℃for 4 h, then modified by MAO is very effective for immobilizing complex 3, the resultant solid catalyst (MSPC-5) shows very high activity in ethylene polymerization, and its kinetics of polymerization is stable during the reaction process. Finally, PEs with spherical morphology and high bulk density (over 0.35g/ml) were obtained, without reactor fouling;5.In this work, polymerization conditions such as alkylaluminums, Al/Zr ratio, temperature and H_2 had a pronounced effect on the activity of MSPC-5 and properties of PE;(3). New MgCl_2-Supported Single-Site Catalysts for Ethylene PolymerizationIn this work, a kind of new MgCl_2 support was obtained by anhydrous MgCl_2 co-milled with solid MAO, and it is a creative contribution. Then some single-site catalysts were supported on the new MgCl_2 support, and the resulted solid catalysts were tested in ethylene polymerization, the results indicated that:1.XRD and IR analyses indicate that MAO does be coordinated with MgCl_2, which is in good agreement with the results obtained by XPS;2.co-mlling time had no obvious effect on the texture of support after 12 hours;3.In this work, MgCl_2 was co-milled with solid MAO for different hours, and then complex 3 was supported on these co-milled supports. It was found that co-milling time markedly influences the activity of solid catalysts, but it had negligible effect on the kinetic profile and the properties of resultant PE.
XPS研究结果表明,MAO不仅仅只和乙醇作用,MAO还与MgCl_2本身有一定的作用,这是一个极为重要的发现;3、通过ICP和EDX表征,发现载体的脱醇温度直接影响着元素在固体催化剂中的含量及分布;4、脱醇温度极大地影响着负载苯氧基亚胺类催化剂的活性和聚合物的性能,特别是原始载体经160℃活化4小时制备得到的固体催化剂MSPC-5的活性明显高于其他脱醇温度条件下制得的固体催化,并且催化剂寿命长,表现出稳定的动力学行为,最终获得了高堆密度(大于0.35g/ml)的球形聚乙烯颗粒;5、本文选择MSPC-5为研究对象,考察了聚合反应参数对催化剂的活性及其聚合物的影响,研究发现:不同的烷基铝对催化剂具有非常重要的影响,特别足TIBA对MSPC-5的助催化活性最高,烷基铝的加入量有一个较佳值,聚合温度为80度时活性最高,H_2的加入使催化剂的活性明显降低且聚合物的分子量也减小;、新型氯化镁载体负载单活性中心催化剂催化乙烯聚合本文创造性采用固体MAO与无水氯化镁直接进行共研磨,制备出了一种的新型的氯化镁载体,并将该载体用于多种单活性中心催化剂的负载化研究,研究表明:1、通过BET、XRD的表征,再次证实了MAO与MgCl_2之间具有直接作用,与XPS的研究结果相一致;2、当研磨时间高于12小时时,延长研磨时间对载体的结构没有显著的影响;3、将配合物3负载于共研磨时间不同的一系列载体上,乙烯聚合结果表明,尽管共研磨时间对负载催化剂的活性具有明显的影响,但是它对聚合物的性能以及催化剂的影响不明显。

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

The influences of Ce on the microstructure and mechanics performances of Ti-Fe-Mo-Mn-Nb-Zr alloys were studied and presented in this paper. The microstructure of no-Ce Ti-Fe-Mo-Mn-Nb-Zr alloy was thick, long and dendritic,and the microstructure of alloy was fined by Ce. With the increase in Ce wt%, the microstructure became equiaxial gradually.
研究了稀土 Ce对 Ti- Fe- Mo- Mn- Nb- Zr合金组织与力学性能影响,结果表明:不含 Ce的为粗大的长枝晶组织,加入 Ce后组织有所细化,并随 Ce量增加而逐渐等轴化,直至形成等轴晶;硬度方面随 Ce的加入有所降低;在 Ce含量较少时随 Ce的增加压缩强度也增加,但当 Ce含量增大一定量时,Ce增加降低了压缩强度。
