查询词典 olefin hydrocarbon

"Olefin Any unsaturated hydrocarbon containing one or more pairs of carbon atoms linked by a double Bond."

烯烃：含有一对或多对由双键连接的碳原子的一类不饱和烃。

The result shows at the mild condition chain olefin that nCl7, polyethylene can be cracked into solutions of ethane, propane, butane, benzene and toluene and other small molecular compounds, polyethylene reacted fluids are mainly composed of a-olefin at the range 12 to 38, by which α-ωdiene, saturated hydrocarbon and aromatic hydrocarbon, anthracene, phenanthrene of albocarbon series are contained.

结果表明，在温和条件下可以将链状烷烃如正十七烷烃、聚乙烯通过微波及炭催化剂的作用，裂解成乙烯、丙烷、丁烷、苯、甲苯等溶剂及小分子化合物。聚乙烯反应液体产物以碳数在12~38范围的α-烯烃为主，也产生α-ω二烯、饱和烃及芳烃，芳烃主要有萘系列、葱、菲等。

The kinetics model was gotten based on the alkyl mechanism, light olefins re-absorption and re-reaction. The kinetics experiment is carried out over the selected Fe-Mn-K catalyst, and the kinetics model parameters is got base on the kinetics experiment data. The parameters explain the reaction results that the carbon monoxide content is high, the methane content is the biggest of the hydrocarbon products and the olefin content is bigger than the corresponding alkenes content.

本文同时对该反应的反应机理和动力学进行了研究，以烷基机理为基础，建立了考虑烯烃再吸附和二次反应的动力学模型，并在选定的催化剂上进行了相应的动力学实验，结合动力学实验数据计算得到了相应的动力学模型参数，模型参数值解释了反应产物中CO的含量较高，以及烃类产物中CH4含量最高和烯烃含量大于相应的烷烃含量。

In particular, the present invention concerns a process and an apparatus for continuous polymerisation olefin monomers like ethylene and other monomers, wherein an olefin monomer is polymerised in slurry phase in an inert hydrocarbon diluent in at least one loop reactor.

本发明尤其涉及连续聚合烯烃单体如乙烯和其它单体的方法和设备，其中烯烃单体在至少一个回路反应器内惰性烃稀释剂中的浆料相内聚合。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
