【摘要】 本文分析了当前糠醇生产的现状,指出液相法加氢工艺是糠醇生产的主流工艺,铜铬催化剂由于其本身具有良好的性能在糠醇生产中仍然占有重要地位;随着糠醇生产中劳动保护措施的完善,铜铬催化剂对糠醇生产人员的健康影响已微乎其微;而废催化剂的回收技术又推动了该催化剂的发展;在国内,铜铬催化剂虽然种类较多,但性能均远不及国外某公司产品,生产如此低性能的催化剂是对资源的一种浪费,所以有必要开发高性能的新一代催化剂。本文借鉴国内外大量文献,并以该进口催化剂与国产催化剂为样品,采用现代催化剂分析技术剖析,通过对其分析结果的研究,推测出适合该加氢反应的催化剂的组成、物相及孔结构,据此确定初步的可用原料和实验方案。然后通过实验筛选出适宜的实验方案,在制备实验中进一步考察了制备条件对催化剂性能的影响,从而得出催化剂的制备参数。由于糠醛原料的的质量严重影响着糠醛加氢反应的速率和选择性,而工业糠醛原料质量参差不齐,为确保改性铜铬催化剂在糠醇生产中的使用效果,本文还考察了不同氧化钙加入量对该加氢反应的影响,得出工业生产中适宜的氧化钙加入量;在改性铜铬催化剂的研制小试成功后,该催化剂又成功地应用于济南圣泉公司糠醇工业生产,并取得了与进口催化剂同等的使用效果,其性能明显好于国产催化剂,这充分表明所开发的铜铬催化剂已达到国外同类产品的水平,可做为当前国产铜铬催化剂的替代技术。更多还原

【Abstract】 After analysing the condition of furfural alcohol production, the paper points out that the main technology to produce furfural alcohol is hydrogenation in liquid phase. Owe to itself performance, copper chromite catalyst still plays an important role in furfurol alcohol production. As the improvement of working condition and technique of recycle for used catalyst,copper chromite catalyst does little harm to human beings. All these things accelerate the development of copper chromite catalyst. But the perfomence of copper chromite catalyst produced in civil is far below that from abroad, So it is necessary to develop a high performance one.Studying a lot of related documents , analyzing the copper chromite catalyst made in China and America by modern analysing technique, the composition, crystal structure and grain structure of the catalyst can be deduced, Therefore material and scheme to make experiments can be design primarily; After necessary experiments proper material and scheme can be confirmed; At last some parameters to prepare the catalyst are investigated.Since furfurol quality has an heavy effect on its hydrogenation reaction and furfurol quality of different factories differs largely, the paper also investigates the influence of CaO on furfurol hydrogenation .After the new improved copper chromite catalyst is made successfully in the laboratory, the catalyst is then applyed in industry and achieved a good results which is equal to that of catalyst from abroad and better than that of demestic ones, so the development of improved copper chromite catalyst is successful.更多还原
