The influence of CFC-12 content, effect of fluorination temperature and fluorinating time on the structure and hydrodesulfurization activity of the catalysts were examined systematically. The results revealed that hydrodesulfurization activity of the catalyst fluorinated by 1% CFC-12 at 623 K was obviously improved With an increase of 20%-30% as compared With that of the unfluorinated catalyst, the commercially available BY2 catalyst, and NH4F-fluorinated catalysts.
通过对0.5%~7%各种氟里昂浓度和473~773K各种温度及不同时间氟化处理的样品进行详细考察，发现在623K下由含氟里昂1%的湿空气氟化的载体制备的催化剂样品，其噻吩的加氢脱硫的活性有明显改善，相对於非氟化样品、BY-2工业催化剂以及氟化铵溶液浸渍处理的催化剂活性提高20%~30%，且非常稳定。

At first, the rought C〓F〓 mixed gases are obtained by pyrolysis process of R22. A experimental pyrolysis device is designed and made by ourself. The optimum operating conditions are offered in the paper. Secondly, the much efforts is on the synthesis of R134. After through the discussion of basic thermodynamics and kinetics, selecting and preparating catalyst, it is possible that the synthesis of R134 by pyrolyzed gases hydrogenation. Base on the character of catalytic process, the kinetics equation about C〓F〓 catalytic hydrogenation is established. The rate constant of the reaction is obtained through experiment data regression. In order to achieve higher yield of R134, some optimum technological conditions is determined.
论文首先对R22裂解制成四氟乙烯混合原料气的裂解过程进行了讨论，自行设计和制作裂解反应装置，并确定裂解反应的最佳操作条件；然后，重点对R134的合成进行基础研究，分别从热力学和动力学的角度探讨以含四氟乙烯的R22裂解混合气为原料合成R134这一全新工艺的可能性，选择和制备加氢催化剂，根据催化过程特点建立四氟乙烯催化加氢反应的总包动力学方程，并在此基础上自行设计和制作中试合成装置，获得了以裂解混合气为原料合成R134的最佳工艺条件，为R134的工业化生产提供了必要的理论依据和实验基础。
