项目摘要

A Separate type membrane reactor was developed for much effective reactor performance, in which the chemical reaction equilibrium could be moved toward the products side by adopting good combination of chemical reaction and separation process. Hydrogen strange metals were used as separation membrane material for developing a high performance reactor carrying out the hydrogenation between hydrocarbon and carbon dioxide. Experimental work for the practical use of the reactor was carried out to achieve the desired strength in membrane characteristics. In the palladium membrane, peel problems of membrane by carbonized matter propagation on the catalyst surface were observed, which are vital blows for use. Superior characteristics of LaNi5 and CaNi_5 were found on catalytic ability, selectivity in hydrogen permeation and cost performance.In this study, Separation ability and reaction characteristics were investigated by adopting a continuous tubular type separation membrane reactor. In the reactor, dehydrogenation of saturated hydrocarbons, that is, methane, ethane, propane, n-butane and hydrogenation of carbon dioxide occurred at the other side. These performances were discussed by changing the operating conditions such as metal composition, membrane surface treatment, gas pressure, used gases and so on. Finally selectivity in hydrogen permeation was found for LaNi_5 and CaNi_5 as well as catalyst ability on the above reactions, so the possibility of the labo-scale reactor toward the application is apparent. Furthermore, the development for industrial equipment of the reactor would be expected by the improvements of membrane strength, contractior effects by repetition uses, permeation selectivity, catalyst ability and so on.

开发了一个单独的膜反应器，以实现有效的反应器性能，其中化学反应平衡可以通过采用化学反应和分离过程的良好组合向产物侧移动。氢奇异金属用作分离膜材料，用于开发高性能反应堆，该反应堆在烃和二氧化碳之间进行氢化。进行了反应器实际使用的实验性工作，以实现膜特性的所需强度。在钯膜中，观察到在催化剂表面上通过碳化物质传播的膜问题，这是供使用的重要打击。 LANI5和CANI_5的卓越特征是在催化能力，氢渗透和成本性能的选择性上发现的。在这项研究中，通过采用连续的管状型分离膜反应器研究了分离能力和反应特征。在反应堆中，饱和烃的脱氢作用，即甲烷，乙烷，丙烷，N-丁烷和二氧化碳的氢化发生在另一侧。通过更改工作条件（例如金属成分，膜表面处理，气压，使用的气体等）来讨论这些性能。最终，发现了LANI_5和CANI_5的氢渗透率以及上述反应的催化剂能力，因此显而易见的是Labo尺度反应器对应用的可能性。此外，通过改善膜强度，通过重复用途的合同效应，渗透选择性，催化剂能力等，可以预期反应堆工业设备的开发。
