摘要
纳米材料在化学、电学、光学、磁学和机械等方面具有许多与常规材料不同的奇特性能。这种材料用于工业催化,可以大幅度提高催化效率,节省活性组分用量,减少或避免不利反应;用于化工过滤和分离,可以快速去除杂质,以较低成本获取所需物质;用于对流传热,既可提高传热系数,又可显著节约泵动力;用于辐射传热,可提高加热效率,减少能量损耗;用于流体输送及系统润滑,可提高金属的防腐蚀效果,减少能量消耗,延长机械寿命。纳米科技正在使传统炼油化工的方方面面发生巨变。
Nanomaterials exhibit unique performance over conventional material in chemical, electrical, optical, magnetic and mechanical industries. When it is used in industry catalysis, it can greatly improve catalytic reaction efficiency, save active component requirement and minimize or eliminate undesirable side reactions; When it is applied in chemical filtration and separation, impurity removal is accelerated and the required material is produced at low cost ; If it is utilized in convection heat transfer, the heat transfer coefficient can be increased and the pump power can be saved; When it is selected for radiation heat transfer, the heat transfer efficiency is enhanced and energy consumption reduced. If it is adopted in fluid transfer and system lubrication, the steel＇s corrosion resistance is improved, energy requirement reduced and the service life of mechanical equipment is extended. The nano technology will bring a great change to all aspects of refining and chemical industries.
